Do Cats Recognize Their Name?

 

 

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 CAT GAP

 

Cat gap

From Wikipedia, the free encyclopedia

The cat gap is a period in the fossil record of approximately 25 million to 18.5 million years ago in which there are few fossils of cats or cat-like species found in North America. The cause of the "cat gap" is disputed, but it may have been caused by changes in the climate (global cooling), changes in the habitat and environmental ecosystem, the increasingly hypercarnivorous trend of the cats (especially the nimravids), volcanic activityevolutionary changes in dental morphology of the Canidae species present in North America, or a periodicity of extinctions called van der Hammen cycles.[1]

Cat evolution[edit]

Feliform evolutionary timeline

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 PseudaelurusPseudaelurus 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]

Possible causes[edit]

Hypercarnivorous tendency[edit]

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.

Changes in climate and habitat[edit]

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 hoglike creodonts 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]

Other[edit]

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 Oligocene Epoch. 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 AlaskaGreenland, 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]

Evolution of caniforms during the gap[edit]

Some paleontologists argue that caniforms like Amphicyonidae – "bear dogs" - responded to the cat gap by evolving to become more cat-like, to fill the hypercarnivore ecological 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 hypercarnivorous ecological 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 endemic hesperocyonine canids, with three genera (ParenhydrocyonEnhydrocyon, 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 hemicyonines Cephalogale 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]

Avoid Table Scraps in Your Dog's Diet

Avoid Table Scraps in Your Dog's Diet

We have all done it.  Our cute, little furry friend is practically smiling at us from beneath the kitchen table.  The ears are perked and the tail is wagging.  We know what our dog is after. Just a tiny tidbit from dinner would be delightful, right?  What could it hurt?  It is just a bite or two after all.  

Hold Fido's ears he won't want to hear this.  A dog's diet really should not contain table scraps.  People food is just that...for people.  A dog's nutritional needs are not the same as a human's.  Sure, we eat some of the same things, but feeding your pet from the table is one of the biggest mistakes for  your pet.  A dog's diet doesn't require all the added goodies we put into our meals.

People have problems with obesity.  A dog can have this problem, as well.  If your dog's diet consists mostly of scraps from the dinner table, chances are high that your dog will have trouble maintaining a healthy weight.  Even a few pounds over weight can really make a difference in the quality and length of your pet's life.  Curb the begging and stick to your guns.  

When you have a dog who is not a picky eater, it can be tempting to let your pet be the garbage disposal in the home, but really, this is not a good idea.  Certain people foods can harm your dog and should never be a part of your dog's diet.  Grapes, for example, have been known to cause serious problems for dogs, even death.  Chicken bones and popcorn can also be a problem for your dog.  Permitting large quantities of chocolate can be dangerous in a dog's diet. 

A poor diet even shows up out in the yard.  When your dog's diet is not at its best, your pet's outputs will be greater in size, smell, and mess.  Benefits of choosing a healthy diet for your dog will be noticeable in your pet's health, as well as, during those walks around the block. 

There are a few occasions when a supplement or treat from the kitchen may be alright, but never in excess.  Talk to your veterinarian about healthy snacks for your dog's diet.  If you simply must continue feeding Fido at the table, many vets recommend you give your pet ice cubes or pieces of carrot to munch on between scheduled feeding times.  Providing your pet these healthy alternatives to pizza and cupcakes gives you the freedom to choose a healthy and nutritious snack for your dog's diet.  

So, the next time your beloved pet starts eyeing your grub, redirect his or her attention. Don't reach for your fatty steak or chicken leg.  Instead, toss your buddy a cool, refreshing ice cube to bat around and munch on.  A couple of baby carrots will keep Fido happy and leave you feeling good about your choices for the nutritional value of your dog's diet.  You will know that you are doing your best to maintain a high-quality diet for your pet.

Common Cat Diseases



Cats are fiercely independent and sometimes mysterious, making it challenging for pet parents to tell if something is a minor issue or a serious health problem. That’s why it’s crucial to understand the signs and symptoms of the most common cat health issues, like FIV, FeLV, diabetes, and more.

Read on for a closer look at common cat diseases, their symptoms, and treatment options. Remember, if your cat shows any alarming symptoms, contact your veterinarian. This guide is purely for your information and not meant for diagnosing illnesses.

1. Kidney Disease

Kidneys filter waste and regulate blood and water levels. When they don’t function properly, cats can develop acute renal failure or chronic kidney disease. Acute renal failure develops quickly and can be reversed if diagnosed in time, while chronic kidney disease is incurable but manageable.

Causes: Congenital issues, aging, infections, trauma, blockages, or poison ingestion. Symptoms: Frequent urination, weight loss, excessive drinking, dry coat, vomiting, diarrhea, bloody or cloudy urine.

2. Dental Disease

Did you know that up to 90% of cats over four suffer from dental disease? Common issues include gingivitis, periodontitis, and tooth resorption. Most dental problems can be prevented or treated with proper care.

Symptoms:

  • Gingivitis: Red, swollen, or bleeding gums.
  • Periodontitis: Similar symptoms plus difficulty eating, bad breath, drooling.
  • Tooth Resorption: Pain, drooling, turning head while eating, inability to eat.

3. Diabetes

Cats can develop diabetes if they can’t produce enough insulin or respond to it properly. While serious, diabetes can be managed, and some cats even go into remission with the right care.

Symptoms: Weight loss, increased thirst and urination, lethargy, dehydration, appetite changes, sweet-smelling breath.

4. Feline Immunodeficiency Virus (FIV)

FIV weakens a cat’s immune system, making them more susceptible to other infections. It’s often spread through bite wounds, so outdoor cats are at higher risk.

Symptoms: Gingivitis, loss of appetite, poor coat condition, fever, chronic infections.

5. Feline Leukemia Virus (FeLV)

FeLV is a virus that can cause cancer and is spread through bodily fluids. It weakens the immune system and can lead to anemia.

Symptoms: Seizures, neurological disorders, eye conditions, persistent diarrhea, fever, infections, weight loss, appetite loss.

6. Cancer

Lymphoma is the most common cancer in cats, but many types can occur. Routine vet exams are crucial for early detection and better outcomes.

Symptoms: Weight loss, anorexia, diarrhea, vomiting. Cats with FIV or FeLV are at higher risk.

7. Obesity

If your cat weighs 20% more than their ideal weight, they’re considered obese. Obesity shortens lifespan and increases the risk of diseases.

Risks: Diabetes, joint problems, cancer, heart disease.

8. Pancreatitis

Pancreatitis is inflammation of the pancreas, often accompanied by inflammation in the liver and intestines. The exact cause is unknown, but some cats are more at risk.

Symptoms: Vomiting, fever, abdominal pain, decreased appetite, diarrhea.

9. Hyperthyroidism

This condition affects middle-aged and older cats and is usually caused by benign growths on the thyroid gland, increasing its size and hormone production.

Symptoms: Excessive energy, increased appetite, weight loss, restlessness.

10. Broken Bones

Cats can break bones from falls or other accidents. Prompt veterinary attention is necessary to minimize long-term effects.

11. High-Rise Syndrome

Cats are agile, but falls from heights can still cause serious injuries like broken limbs and fractures.

12. Sneezing

An occasional sneeze is normal, but persistent sneezing with other symptoms like lethargy or nasal discharge may indicate a respiratory infection.

13. Diarrhea

Occasional loose stools aren’t always concerning, but persistent diarrhea should be checked by a vet.

14. Vomiting

Common causes include hairballs and eating too fast, but more serious reasons could be at play.

15. Fleas

Fleas are hard to eliminate and can carry diseases. Regular cleaning and prevention products are essential.

16. Tapeworms

These parasites, often carried through fleas, can be seen in feces. While severe issues are rare, vomiting may occur if tapeworms enter the stomach.

17. Eye Problems

Issues like cataracts and glaucoma can be treated if detected early, highlighting the importance of regular vet check-ups.

18. Heartworms

Heartworms are more common in dogs but can affect cats too, causing respiratory issues. Blood tests are needed for diagnosis.

19. Rabies

Cats are the most common domesticated animal affected by rabies in the U.S. Keeping vaccinations up to date is crucial.

20. Ringworm

This fungal infection causes itching and redness and can be treated with medication.

21. Ear Mites

These parasites cause itching and abnormal ear grooming. Treatment involves cleaning and medication.

22. Constipation

Straining while defecating and small, diarrhea-like feces can indicate constipation. Vet attention is needed if symptoms persist.

23. Food Allergies

Common allergens include beef, fish, chicken, and dairy. Symptoms include skin irritation, diarrhea, constipation, and vomiting.

24. Feline Lower Urinary Tract Diseases (FLUTD)

FLUTD affects the bladder and urethra, causing pain during urination, blood in urine, and urinating outside the litter box.

By staying aware of these common health issues, you can help your cat live a longer, healthier life. As Amanda Nichols from the UK’s Cat’s Whiskers Veterinary Clinic says, “Ensuring they eat a good quality diet and maintain a healthy weight and body and muscle condition score” is key to longevity.
