Discover the benefits of using a retractable leash for your dog walks. Enjoy freedom, control, and safety while transforming your outings into a joyful experience for both.
Walking your dog should be a joy, not a constant struggle with a tangled mess of a leash. Picture this: you’re in the park, your dog spots a squirrel, and before you know it, the leash is a twisted nightmare, and you're left untangling knots instead of enjoying a peaceful stroll. Enter the retractable leash – the unsung hero of the dog-walking world. It’s a game-changer, trust me.
A retractable leash is like giving your dog the freedom to explore while still keeping them safe and under control. It’s like handing a teenager the car keys but with a curfew they can't break. You see, traditional leashes can be so restrictive. They force your dog to stay close, which might be fine in busy streets, but in open spaces, our furry friends deserve a bit more liberty. They want to sniff, explore, and sometimes, just go a little further than usual. A retractable leash lets them do that without any fuss.
Imagine the difference: you’re walking through the woods, your dog spots an interesting scent and starts to pull. With a regular leash, you’d either have to run along or pull them back, breaking their spirit of adventure. But with a retractable leash, you simply press a button, and they get a bit more lead to explore, all while you stay comfortably on the path. It’s like letting out a kite string – controlled, measured, and oh-so-satisfying.
I remember my first walk with a retractable leash. It was a sunny day, and my Golden Retriever, Max, was bouncing with energy. We hit the park, and I let him have his way – within reason, of course. The joy on his face as he realized he had more room to roam was priceless. No more jerky stops, no more frustration from either of us. Just smooth, enjoyable walks. I could finally sip my coffee and enjoy the scenery instead of being a constant tug-of-war referee.
And it’s not just about the freedom; it’s about the control. Retractable leashes come with a locking mechanism that allows you to set the length. So, if you need to keep your dog close in busy areas, it’s just a click away. The transition is seamless – one moment they’re exploring, the next they’re back by your side, safe and sound. It’s like having a leash with a built-in safety net.
Safety is paramount, and the retractable leash delivers. It prevents those nasty surprises when a dog suddenly bolts. With a quick press, you can halt their dash, avoiding potential dangers like traffic or other aggressive dogs. It’s peace of mind on a reel.
Some might argue that retractable leashes are risky, but like any tool, it’s about how you use it. With the right approach, it enhances the walk experience. Train your dog to respond to commands, and the retractable leash becomes an extension of your bond, a trust exercise on a cord.
For those skeptics still clinging to their old, tangled ropes – give the retractable leash a try. It’s not just a leash; it’s a lifestyle upgrade for both you and your dog. It turns every walk into an adventure, every outing into a story worth telling. Your dog deserves that freedom, and you deserve the ease it brings. Embrace the retractable leash revolution and see the difference for yourself.

I’d love to hear your thoughts and experiences with amazing dogs! 🐾
Growing up, our household was never without the pitter-patter of tiny paws, the soft rumble of purrs, and the curious, playful nature of our feline companions. One of my earliest memories is of our family cat, Whiskers, darting around the living room, chasing a ball of yarn with an energy that seemed inexhaustible. Whiskers was an indoor cat, and keeping him entertained was a constant challenge. Back then, cat enrichment was a relatively new concept, and we had to get creative with how we kept him engaged and stimulated.
Fast forward to today, and the landscape of cat care has transformed dramatically. As more and more cat owners understand the importance of mental and physical stimulation for their pets, innovative cat enrichment solutions have emerged to cater to indoor cats. The need to keep indoor cats happy and healthy is paramount, and finding ways to enrich their environment can make a world of difference in their overall well-being.
One of the most fascinating developments in cat enrichment is the advent of interactive toys. These toys are designed to challenge a cat's mind and body, mimicking the hunt-and-capture behavior that cats naturally exhibit. From laser pointers that dart around the room to robotic mice that scurry unpredictably, these toys provide hours of entertainment and exercise. I remember when I first introduced a laser pointer to Whiskers – his eyes would light up with excitement, and he would pounce and chase the elusive red dot, burning off his boundless energy in the process.
Another innovative approach to cat enrichment involves puzzle feeders. These devices make cats work for their food, stimulating their minds and slowing down their eating habits, which is particularly beneficial for cats prone to obesity. Watching Whiskers tackle a puzzle feeder for the first time was both amusing and rewarding. He would paw and nudge at the feeder, figuring out how to release the kibble, his natural hunting instincts kicking in. It not only provided him with mental stimulation but also made mealtime more engaging.
Indoor cats also benefit greatly from vertical spaces. Cats love to climb and perch, and providing them with opportunities to do so can significantly enhance their living environment. Cat trees, shelves, and window perches allow cats to explore different heights, satisfying their natural curiosity and desire to survey their territory from above. I remember installing a cat tree for Whiskers; it quickly became his favorite spot in the house. He would lounge on the top perch, gazing out the window, or playfully bat at the dangling toys attached to the tree.
In addition to physical enrichment, sensory stimulation plays a crucial role in a cat's well-being. Cat-safe plants like catnip, silvervine, and cat grass can be introduced to an indoor environment, providing both olfactory stimulation and a healthy snack. Whiskers would often roll around in delight after a few sniffs of catnip, his playful antics a testament to its stimulating effects. Similarly, cat-friendly herbs like mint and parsley can be grown in small pots, offering an engaging and safe way for cats to indulge their senses.
Social interaction is another key element of cat enrichment. While cats are often seen as independent creatures, they still require social engagement with their human companions. Regular play sessions, grooming, and simply spending time together can strengthen the bond between a cat and its owner. I fondly recall the evenings spent with Whiskers curled up on my lap, purring contentedly as I stroked his fur. These moments of connection were not just enjoyable for him but deeply fulfilling for me as well.
Furthermore, the use of technology in cat enrichment has opened up new possibilities. Cat-specific apps and videos, designed to capture a cat's attention, can be used to engage their curiosity. These digital toys often feature moving objects, birds, or fish that cats can "hunt" on a screen. While Whiskers was a bit skeptical of the tablet at first, he soon became intrigued by the moving images, pawing at the screen with fascination.
Environmental enrichment also includes creating a safe and stimulating outdoor experience for indoor cats. Catios – enclosed patios for cats – allow them to experience the outdoors safely. These structures provide fresh air, new smells, and the sights and sounds of nature without the risks associated with free roaming. I had always wished I could give Whiskers a taste of the outside world without compromising his safety, and a catio would have been the perfect solution.
Lastly, regular rotation of toys and enrichment activities is essential to prevent boredom. Introducing new toys, rearranging furniture, or even setting up a new play area can keep things fresh and exciting for indoor cats. Whiskers always enjoyed exploring new additions to his environment, and I found that even small changes could reignite his curiosity.
Incorporating innovative cat enrichment for indoor cats is not just about keeping them occupied; it's about enhancing their quality of life. By providing a stimulating environment, interactive toys, puzzle feeders, vertical spaces, sensory experiences, social interaction, and safe outdoor exposure, we can ensure our feline friends lead happy, healthy, and fulfilled lives. Looking back, I realize that every effort we made to enrich Whiskers' life was rewarded tenfold with his joy, health, and the deep bond we shared. Today's cat owners have an array of tools and resources at their disposal to keep their indoor cats thriving, making it easier than ever to ensure they are truly feline fine.

Prehensile Lips: Horses use their lips to explore and grasp objects. Their lips are highly sensitive and dexterous, which helps them pick up food, untie knots, and even open gates.
Incredible Memory: Horses have excellent memories. They can recognize other horses and humans after long periods apart and often remember complex paths and locations.
Eyesight: Horses have one of the largest eyes of any land mammal and their eyes are positioned on the sides of their heads. This gives them nearly 360-degree vision, allowing them to see predators from almost any direction. However, this positioning also creates a blind spot directly in front and behind them.
Sleeping Habits: Horses can sleep both lying down and standing up thanks to a special locking mechanism in their legs called the "stay apparatus," which allows them to relax their muscles and doze without collapsing.
Speed and Endurance: The fastest recorded sprinting speed of a horse was approximately 55 mph (88.5 km/h). Besides speed, some horse breeds, especially those used in endurance riding, can travel over long distances for extended periods.
Horse Years: Horses have different aging milestones compared to humans. A one-year-old horse is roughly akin to a 6.5-year-old human in terms of maturity. By the time they are five, they are considered adults, similar to a human in their early 20s.
Communication: Horses communicate through vocalizations like neighing and whinnying, and non-verbal cues such as ear position, hoof stomping, and tail swishing. These signals can convey everything from excitement to stress or discomfort.
Social Structure: Wild horses typically live in small groups called bands or herds, led by a dominant mare and protected by a stallion. The social structure is complex and helps them protect each other from predators.
Domestication History: Horses were first domesticated around 3500 BCE, likely in the steppes of central Asia. Since then, they have been used for companionship, labor, and transportation, significantly shaping human history.
Variety of Breeds: There are over 300 different breeds of horses, each with unique characteristics tailored to various uses. From the tiny Shetland pony to the majestic Arabian, there's incredible diversity within the species.
These cat toys are must-haves for endless feline fun! From laser pointers to interactive feather teasers, keep your kitty engaged and thrilled for hours.
When it comes to keeping our feline friends entertained, not all cat toys are created equal. There are those toys that catch their interest for a fleeting moment and then there are the legendary ones – the cat toys cat toys that guarantee hours of playtime fun. You know, the kind of toys that have your kitty chasing, pouncing, and batting around like they’re on a never-ending adventure. Let me tell you, these aren't just any ordinary toys. These are the must-haves in your pet arsenal if you want to see your furry friend at their happiest and most active.
Imagine this: you come home after a long day, and there’s your cat, eyes wide with excitement, darting around the living room in pursuit of a laser pointer. It’s a simple gadget, sure, but it turns your home into a cat-sized carnival. The unpredictability of that little red dot ignites their primal hunting instincts, and before you know it, they’re leaping over furniture and doing mid-air spins. It’s a workout for them and a comedy show for you. Win-win!
But the laser pointer is just the beginning. Let’s talk about the marvel of interactive toys. Enter the automated feather teaser. Picture a small, spinning device with a colorful feather attached, twirling and flicking unpredictably. Your cat won’t be able to resist stalking and pouncing on it, as if it’s a bird fluttering about. Hours of solitary playtime are virtually guaranteed, making it perfect for those days when you’re too busy to dangle a toy yourself.
Now, if you think feathers and lights are the only ways to thrill your feline, you’re in for a treat. Have you ever seen a cat in a tunnel toy? These crinkly, collapsible tunnels mimic the tight, hidden spaces cats love to explore. Add a few peep holes and watch as your cat zips in and out, pawing at toys you strategically place around. The sheer joy of ambushing imaginary prey – or even you as you walk by – is unmatched. It’s like giving them their personal playground.
Speaking of playgrounds, let’s not forget about the climbing toys. Cat trees and scratch posts aren’t just for scratching; they’re multi-level havens for climbing, lounging, and playing. Imagine a towering structure filled with dangling toys, scratching surfaces, and cozy perches. Your cat can spend hours scaling to the top, batting at hanging toys, and then collapsing in a plush hammock for a nap. It’s their kingdom, and they reign supreme from up high.
But what about those classic toys that never go out of style? We’re talking about catnip mice and jingle balls. These humble toys might seem simple, but their appeal is timeless. Stuff a fabric mouse with some high-quality catnip, and suddenly you have a toy that your cat will carry around, toss in the air, and bunny kick like it’s their mortal enemy. Jingle balls, with their enticing sounds, can turn any mundane moment into a play session. Roll one across the floor, and watch your cat dart after it, determined to catch the elusive jingling prize.
For the tech-savvy pet owners, there’s even more to explore. High-tech toys, like robotic fish that swim around in water bowls or laser towers that randomly move the light beam, can keep your cat on their toes. These innovative toys are designed to stimulate your cat’s mind and body, ensuring they get their daily dose of exercise and excitement, even if you’re not around to play.
So, why settle for a bored kitty when you can have one that’s exhilarated and engaged? These toys don’t just guarantee hours of playtime fun; they enrich your cat’s life, keeping them healthy, happy, and thriving. And let’s face it – a entertained cat means fewer shredded curtains and more peaceful moments for you. Investing in these top-notch cat toys is a no-brainer for any cat owner who wants to see their furry friend live their best nine lives.

I've always been a dog person. Growing up, we had a series of boisterous canines, each one seemingly more loyal and loving than the last. It wasn't until I moved into my first apartment and adopted a rescue cat named Whiskers that I began to understand the mysterious and captivating world of felines. I remember the day I brought him home, his eyes wide with curiosity and perhaps a little trepidation. As the weeks went by, I began to wonder: do cats recognize their names?
Whiskers was a peculiar creature. Unlike dogs, who eagerly respond to their names with wagging tails and boundless energy, Whiskers seemed indifferent. He would occasionally flick an ear or glance in my direction when I called him, but his responses were inconsistent at best. This led me on a journey to uncover the truth about whether cats recognize their names.
The answer, it turns out, is both fascinating and complex. Recent studies have shown that cats do recognize their names, but their reaction to them is different from what we might expect from other pets. This difference is rooted in their evolutionary history and social behavior. Unlike dogs, which were domesticated to be companions and work alongside humans, cats were domesticated in a more solitary and independent manner.
In a landmark study conducted by Atsuko Saito, a behavioral scientist at Sophia University in Tokyo, researchers observed how cats responded to hearing their names. The study involved 78 cats from various households and a cat café, ensuring a diverse sample. The researchers played recordings of the cats' owners calling their names, as well as recordings of strangers and other familiar and unfamiliar words. The results were intriguing: the cats showed a noticeable response to their names, such as moving their ears, heads, or tails, even if they didn't always come when called.
This study provided compelling evidence that cats can indeed distinguish their names from other words. However, the subtlety of their reactions often leads owners to believe that their feline friends are indifferent. Unlike dogs, who have been bred for sociability and responsiveness to human commands, cats have retained much of their independence. Their evolutionary background as solitary hunters means they are less likely to exhibit overt responses to their names unless there is a clear benefit, such as food or affection.
Whiskers, like many cats, likely recognized his name but chose to respond on his own terms. This behavior aligns with the findings of the study. Cats are highly attuned to their environment and can discern sounds and cues that are relevant to them. They may recognize their names and choose to ignore them, a trait that has often been mistaken for aloofness but is more accurately a reflection of their independent nature.
Understanding that cats recognize their names but respond selectively offers valuable insights into how we can better communicate with our feline companions. Positive reinforcement, such as offering treats or affection when they respond to their names, can encourage more consistent reactions. This approach not only helps in training but also strengthens the bond between owner and cat.
Another fascinating aspect of cats recognizing their names is their ability to associate sounds with specific outcomes. Just as they learn the sound of a can opener or the jingle of their favorite toy, they can learn to associate their names with positive experiences. This associative learning is a powerful tool that can be used to enrich their environment and improve their quality of life.
Reflecting on my experiences with Whiskers, I began to appreciate the subtle ways he communicated and interacted with his surroundings. His occasional acknowledgment of his name, whether through a slow blink or a gentle head tilt, was his way of engaging with me on his own terms. This understanding deepened our connection and helped me to respect his individuality and intelligence.
In conclusion, cats do recognize their names, but their responses are often understated and influenced by their unique evolutionary history and social behaviors. Unlike dogs, who are eager to please and respond to commands, cats maintain a level of independence that can be misinterpreted as indifference. By recognizing and respecting their individuality, we can foster stronger, more meaningful relationships with our feline companions.
If you have a cat, pay attention to the subtle cues and responses they give when you call their name. You might be surprised to find that, like Whiskers, your cat is more attuned to you than you realized, engaging with you in their own distinctive and charming way.
The Tale of Whiskers: Navigating Life with Cat Dander
The first time I met Whiskers, it was a damp Saturday afternoon. The rain tapped a soft rhythm against the window panes, and the smell of freshly brewed coffee filled the room. Whiskers, a stray tabby with an air of nonchalance, had taken refuge on my porch. His green eyes sparkled with a mix of curiosity and caution as he peered through the glass door.
It didn’t take long for Whiskers to charm his way into my home and heart. However, what I didn’t anticipate was the invisible companion he brought along: cat dander. Despite his sleek fur and endearing purrs, Whiskers was a walking bundle of allergens, particularly cat dander, which is known to cause a variety of allergic reactions.
At first, I wasn’t even aware of the concept of cat dander. I had always thought allergies were more about the fur itself. But as I started experiencing persistent sneezing, itchy eyes, and a runny nose, I began to investigate. It turns out, cat dander is a common allergen. It's composed of tiny, even microscopic flecks of skin shed by cats, often alongside dried saliva. Whiskers, being a meticulous groomer, was a major producer of these allergenic particles.
Living with cat dander isn’t just about managing symptoms; it's about understanding and mitigating its effects. The initial step in our journey was to ensure Whiskers was regularly groomed. This not only reduced the amount of dander he produced but also helped in minimizing the shedding of loose fur. I found that using a damp cloth to wipe him down worked wonders. It trapped dander particles that would otherwise float around and settle on various surfaces.
Another significant change was in our cleaning routine. Vacuuming became a daily ritual, and investing in a vacuum cleaner with a HEPA filter made a noticeable difference. HEPA filters are designed to trap small particles, including cat dander, which regular vacuums might miss. Alongside vacuuming, frequent washing of Whiskers’ bedding and my own linens was crucial. Hot water washes effectively removed dander clinging to fabrics.
Despite these efforts, cat dander has a way of sneaking into places you least expect. The air itself can carry these tiny particles, leading to continuous exposure. To combat this, I added air purifiers to my home, particularly in the living and sleeping areas. These devices worked tirelessly to remove airborne allergens, making the environment more breathable and less irritating.
Understanding the nature of cat dander also led me to explore more holistic approaches. One surprising discovery was the role of diet. Both for Whiskers and myself, a healthy diet contributed to better skin health, reducing dander production. For Whiskers, a diet rich in omega-3 fatty acids helped maintain a healthy coat, which in turn, reduced shedding and dander. For me, staying hydrated and consuming anti-inflammatory foods like leafy greens and berries helped alleviate the symptoms of my allergies.
Of course, there were days when managing cat dander felt overwhelming. On such days, I turned to allergy medications for relief. Antihistamines were particularly effective in controlling symptoms, allowing me to enjoy time with Whiskers without the constant discomfort of allergies. Consulting with a healthcare professional provided insights into the best options for my specific situation.
Building a life with Whiskers meant making adjustments, but the joy he brought into my home was worth every effort. Cat dander, though a challenge, became a manageable part of our routine. The bond we shared grew stronger as we navigated these challenges together. Whiskers became not just a pet, but a cherished member of the family.
As I look back on the journey with Whiskers, I realize that living with cat dander taught me a great deal about patience, adaptability, and the lengths we go to for those we love. It’s a testament to the fact that even the smallest creatures, with their silent challenges, can leave the largest impacts on our lives.
All modern carnivorans, including cats, evolved from miacoids, which existed from approximately 66 to 33 million years ago. There were other earlier cat-like species but Proailurus (meaning "before the cat"; also called "Leman's Dawn Cat"), which appeared about 30 million years ago, is generally considered the first "true cat".[2]
Following the appearance of the dawn cat, there is little in the fossil record for 10 million years to suggest that cats would prosper. In fact, although Proailurus persisted for at least 14 million years, there are so few felid fossils towards the end of the dawn cat's reign that paleontologists refer to this as the "cat gap". The turning point for cats came about with the appearance of a new genus of felids, Pseudaelurus.[2]
The increase in disparity through the early Miocene occurs during a time when few feliform fossils have been found in North America. The hypercarnivorous nimravid feliforms were extinct in North America after 26 Ma and felids did not arrive in North America until the Middle Miocene with the appearance of Pseudaelurus. Pseudaelurus crossed over to North America by way of the Bering land bridge from surviving populations in Asia 18.5 million years ago. All modern-day cats are descended from Pseudaelurus.
Nimravids and barbourofelids were saber-toothed cat-like animals of the families Nimravidae and Barbourofelidae, respectively. Although not "true cats" of the family Felidae, they are closely related to felids. The Nimravidae are either basal feliforms or a sister group to both feliforms and caniforms, while the Barbourofelidae are a sister group to the Felidae. Physically, some Nimravidae and Barbourofelidae resembled the saber-toothed cat Smilodon, which would not appear until many millions of years later. Nimravidae also became extinct in North America during the "cat gap".[3]
The history of carnivorous mammals is characterized by a series of rise-and-fall patterns of diversification, in which declining clades are replaced by phylogenetically distinct but functionally similar clades. Over the past 50 million years, successive clades of small and large carnivorous mammals diversified and then declined to extinction. In most instances, the cause of the decline was energetic constraints and pervasive selection for larger size (Cope's rule) that lead to hypercarnivory dietary specialization. Hypercarnivory leads to increased vulnerability to extinction.
The nimravids were large cat-like animals that occupied this ecomorphic niche in the ecosystem until 26 Ma. It is highly likely that their hypercarnivory led to their extinction in North America. After the extinction of the nimravids there were no other feliform or felid-like species until other felids arrived from Eurasia after crossing the Bering land bridge 18.5 million years ago. During this time there was great diversity among the other carnivorous mammals in North America – both hypocarnivorous and hypercarnivorous species – and other hypercarnivorous species existed before, during, and after the cat gap.
Many cats tend to be arboreal hunters. The disappearance of forests in North America may have caused the mass extinction.
Another possible explanation for the extinction of feliforms in North America is changes in the ecology of the continent. Evidence from the geologic temperature record shows that the earth was experiencing a period of global cooling, causing forests to give way to savannas.[2] Climatic changes to arid conditions that muted variation at about 25.8 Ma coincides with the first appearance of hoglikecreodonts and of pocket gophers, and this also is the beginning of the "cat gap" and the "entelodont gap", a period of some 7 million years when there were no nimravids, felids, or entelodonts in North America. Faunal overturn at 25.8 Ma is the basis for division of the Arikareean time period (30.5–19 Ma), and the Arikareen NALMA (North American Land-Mammal Ages), into the Monroecreekian period (29.5–25.8 Ma), and then the Harrisonian period (25.8–23.5 Ma).[4]
Why did these cat-like creatures die out in North America (while surviving in Eurasia) with no replacement by the true cats? Their fate may be owed to the same factors that created the diversity of herbivorous mammals, for most cats need forest or cover from which to hunt. In an increasingly open America the nimravids may have found themselves without an ecological perch to hunt from, particularly if the competition with dogs prevented them from colonising the savannas.[5]
Volcanic activity has also been promoted as a possible cause of the cat gap as well as other extinctions during this time period. The La Garita Caldera is a large volcanic caldera located in the San Juan Mountains in southwestern Colorado, United States, and is one of a number of calderas that formed during a massive ignimbrite flare-up in Colorado, Utah, and Nevada during the OligoceneEpoch. The La Garita Caldera was the site of the Fish Canyon eruption, an enormous eruption about 27 million years ago. The scale of the Fish Canyon eruption was far beyond anything known in human history (erupting more than 10,000 km3 or 2,400 cu mi for a VEI 8+ magnitude), and was possibly the most energetic event on Earth since the Chicxulub impact, which is thought by many paleontologists to have caused the extinction of the dinosaurs in the Cretaceous–Paleogene extinction event. The resulting explosive volcanism probably ejected large amounts of dust and debris into the stratosphere causing major cooling (see volcanic winter). Climatic effects could also have been caused by sulphur ejected into the stratosphere, which rapidly converts to sulphuric acid, an aerosol which cools the troposphere by blocking incoming solar radiation.
Another possible cause of the cat gap could have been the Late Cenozoic Ice Age that began 33.9 million years ago. This ice age caused glaciation in Antarctica that eventually spread to Arctic regions of southern Alaska, Greenland, and Iceland. Glaciers on the North American continent, as well as the cooling trend, could have made the ecosystem uninhabitable for feliformia cat-like species, although habitable for cold-weather caniformia species such as canids (dog-like species), mustelids (weasel-like species), and ursids (bear-like species).
There is also evidence that during the Miocene a sill surrounding the Arctic Ocean, known as the Greenland–Scotland Ridge, subsided, allowing more cold polar water to escape into the North Atlantic. As the salinity of the North Atlantic grew and as outflow of cold polar water increased, so the thermohaline circulation increased in vigour, providing the mild winter temperatures and large amounts of moisture to the North Atlantic, which are prerequisites to the build-up of the large continental ice caps on the adjacent cold continents.[6]
Some paleontologists argue that caniforms like Amphicyonidae – "bear dogs" - responded to the cat gap by evolving to become more cat-like, to fill the hypercarnivoreecological niche[7]
It has been suggested by some that as a result of the cat gap caniforms (dog-like species including canids, bears, weasels, and other related taxa) evolved to fill more carnivorous and hypercarnivorousecological niches that would otherwise have been filled by cats.[7] This conclusion, however, is disputed.[8]
During or just prior to this "cat gap", numerous caniform species evolve catlike features indicative of hypercarnivory, such as reduced snouts, somewhat enlarged canines, and fairly extreme reduction of their crushing molars. In North America the first caniform group of moderate body size to move in the direction of hypercarnivory were the endemichesperocyonine canids, with three genera (Parenhydrocyon, Enhydrocyon, and Mesocyon), ranging in size from jackals to small coyotes, appearing in the early Arikareean (circa 28 MYA). Notably, these three evolved alongside the last hyaenodont and the remaining three nimravids, two of which were puma-sized. The small hypercarnivorous canids were soon joined by and ultimately replaced by numerous species from other families which also had evolved more specialized meat-eating teeth and skulls. These included at least three larger genera of similarly adapted amphicyonids, one endemic (Daphoenodon) and two from the Old World (Temnocyon and Mammocyon), a leopard-sized mustelid (Megalictis) as well as two hypercarnivorous bears, the hemicyoninesCephalogale and Phoberocyon.[7]
However, other paleontologists take issue with this conclusion:
It has been suggested that canids evolved hypercarnivorous morphologies because feliforms were absent during this period (the "cat-gap", 26–16 Ma). The data presented here do not support this hypothesis. In the calculated morphospace ... Canids never occupy the area of morphospace in which felids, nimravids, and hypercarnivorous creodonts are found. More pertinent to the issue at hand, however, is that most of these hypercarnivorous canids were present before the disappearance of the nimravids, and all became extinct before the appearance of felids ... There was a progressive and marked decrease in hypercarnivorous forms during the "cat-gap". 28–20 Ma are characterized by above average extinction intensities and below average origination intensities. 20 Ma was marked by an increase in origination intensity, and 18 Ma showed a decrease in extinction intensity and a large increase in origination intensity. Nonetheless, despite increased origination intensities and decreased extinction intensities near the end of the "cat-gap" (20–16 Ma), there was still no substantial invasion of hypercarnivorous morphospace until the immigration of felids into North America.[8]
