What Makes a Cat Fluffy?
The fluffy fur that many cats are known for is caused by a genetic mutation in a gene called Fibroblast Growth Factor 5 (FGF5). This gene controls hair length in cats. The normal version of the gene codes for short hair, but certain mutations lead to long or fluffy fur. As described by UC Davis Veterinary Genetics Laboratory, “Cats with an FGF5 mutation have long hair” (UC Davis).
Over time, cat breeders selectively bred cats that had this long fur mutation. By breeding two long haired cats together, they were able to develop specific cat breeds that consistently had fluffy coats, such as Persians and Maine Coons. So while fluffiness originally arose from natural genetic variation, human driven selective breeding amplified the trait and created distinct fluffy breeds.
It’s important to note that a cat’s fur length does not change its classification as a mammal or status as a feline. Fluffiness is simply an aesthetic trait that has been artificially selected for by humans. The mutations causing it do not alter the biological class or species of domestic cats.
Mammals Defined
Mammals are a class of vertebrate animals characterized by several key features. According to Britannica.com, the hallmarks of mammals include advanced reproduction and parental care, behavioral flexibility, and endothermy.
Some of the main characteristics that define mammals include:
- Hair and fur – Mammals are covered in hair or fur.
- Mammary glands – Female mammals produce milk through mammary glands to feed their young.
- Single-boned lower jaws – The lower jaws of mammals consist of just one bone.
- Tooth replacement – Mammals only replace their teeth once during their lifetime.
- Three middle ear bones – Mammals have three small bones in their middle ear.
- Endothermy – Mammals are able to regulate their own body temperature.
Cats display all of these key mammalian traits. They have fur coats, mammary glands to feed kittens, single-boned lower jaws, and the same tooth replacement patterns. Cats are also endothermic, meaning they can maintain a consistent internal body temperature.
Therefore, there is no doubt that cats, including fluffy cats, belong to the mammalian class of animals.
All Domestic Cats are Mammals
All domestic cats, including fluffy ones, belong to the biological family Felidae which consists of all cats large and small. According to the Encyclopedia Britannica, members of the Felidae family are classified as mammals because they share the key mammalian traits of being warm-blooded, having fur or hair, and feeding their young with milk produced by the mother’s mammary glands (Source).
Some key features that identify felines like domestic cats as mammals include:
- Having a vertebral column or backbone
- A four-chambered heart
- Separate circulatory systems for oxygenated and deoxygenated blood
- Complex brains capable of learning, emotion, and logical thinking
- Live birth as opposed to laying eggs
A cat’s fluffiness or fur length has no impact on its status as a mammal. Fluffy coats are simply a genetic variation that does not alter the animal’s underlying biology or classification. All domestic cat breeds, whether they have short sleek coats or long fluffy fur, are members of Felidae and therefore mammals (Source). Their fur thickness does not make them any more or less of a mammal.
Fluffy Coat Variations
There are many breeds of domestic cat that are known for their fluffy, soft coats. Some of the most popular fluffy breeds include:
- Persian – This breed is one of the fluffiest, with a long, thick, flowing coat that requires daily grooming. Persians have a rounded head and snub nose. Their coats come in a variety of colors and patterns (https://www.thesprucepets.com/fluffy-cat-breeds-7692786).
- Ragdoll – Ragdolls have a medium-long silky coat that’s soft and plush. They are known for being relaxed and docile. Ragdolls are pointed cats, meaning their extremities are darker than their body (https://www.purewow.com/family/fluffy-cat-breeds).
- Norwegian Forest Cat – This ancient breed adapted to cold Scandinavian winters with its long, water-resistant double coat. They have an athletic, muscular body and make affectionate pets (https://www.thesprucepets.com/fluffy-cat-breeds-7692786).
- Maine Coon – As one of the largest domesticated breeds, the Maine Coon has a shaggy, heavy coat. Its expressive tufted ears and furry paws are breed trademarks. They make outgoing, friendly companions (https://www.purewow.com/family/fluffy-cat-breeds).
While the length, texture, and density of the coat varies between fluffy breeds, they all share the fact that they are domestic cats, and therefore mammals. Regardless of their distinctive fluffy coats, all cat breeds belong to the Felis catus species.
Fluffy Big Cats
Some of the largest wild cats in the world also exhibit fluffy coats. Lions are an iconic example, with males sporting thick, fluffy manes around their heads. The lion’s mane helps demonstrate strength and provides extra protection in territorial battles (source). Fluffy snow leopards also inhabit the mountains of Central Asia, with thick fur adapted to the cold climate. Their long, fluffy tails help them balance and stay warm (source). Despite their fluffy appearances, big cats like lions and snow leopards are still very much mammals.
Other large fluffy cats include Pallas cats, with extremely dense light-grey fur over their small bodies. Pallas cats are native to parts of Central Asia and rely on their thick coats as protection from predators. Though they may look extra fluffy, they are members of the mammalian genus Otocolobus (source). The extra fluff on these wild felines helps them thrive in harsh environments, while fully retaining their status as mammals.
Caring for Fluffy Coats
Fluffy cats require regular grooming and maintenance to keep their coats looking their best. Their long, thick fur is prone to tangles and mats which can be painful or irritating if left untreated. Here are some tips for properly caring for a fluffy cat’s coat:
Brush thoroughly 1-2 times per week using a stainless steel comb to remove dirt, debris, loose hair and distribute skin oils. Be gentle, taking care not to pull on tangles. Small mats can be worked out with fingers but larger ones may need to be clipped out.1
Bathe a fluffy cat every 4-6 weeks using a moisturizing cat shampoo. Avoid over-bathing which can dry out the skin. Be sure to fully rinse and properly dry the thick coat after.
Trim the fur between foot pads if it gets overly long to prevent matting and discomfort. Use rounded tip clippers and cut carefully.
Pay attention to the tail, belly and backside area where fur can easily become soiled or matted. Keep these areas clean and neatly trimmed as needed.
Use a stainless steel flea comb while grooming to help remove fleas and eggs. Check for any skin irritation, inflamed spots or evidence of parasites.
Maintaining a fluffy cat’s coat takes time and care but is essential to their health and comfort. With regular brushing, bathing and trimming, their fabulous fluffiness will be easier to manage.
Myths About Fluffy Cats
There are many myths and misconceptions surrounding fluffy cats. One common myth is that fluffy cats are hypoallergenic. This simply isn’t true – all cats produce allergens like Fel d 1 in their saliva, skin and fur, regardless of coat length or fluffiness. Fluffiness does not affect a cat’s ability to trigger allergies (Cat Myths and Legends).
Another myth suggests that fluffy cats don’t groom themselves as well as other cats. Fluffy cats are just as meticulous groomers as any other cat. Their fluffy fur may make it look messier faster, but they dedicate the same amount of time to licking and cleaning themselves. With proper brushing by owners, fluffy coats can stay neat and tidy.
There’s also a myth that fluffy cats are less intelligent or aloof. There is no correlation between coat fluffiness and personality traits. Fluffy cats have the same range of intelligence, independence, playfulness and affection as smooth coated cats. Their fur has no impact on their intellect or behavior.
Finally, some believe that fluffy cats must be a different species than other domestic cats. This is false – fluffiness is simply a coat trait, not an indicator of species. Fluffy coated cats are every bit as much mammals and members of the Felis catus (domestic cat) species as their short haired counterparts. No matter how fluffy their fur is, they remain mammals biologically.
Fluffy Cats in Pop Culture
Fluffy cats have become pop culture icons thanks to their enduring popularity in movies, TV shows, memes, and social media. Some of the most famous fluffy felines include:
Puss in Boots from the Shrek movies – This iconic ginger cat first appeared in Shrek 2 in 2004, wearing his signature cavalier hat and boots. Voiced by Antonio Banderas, Puss in Boots has since starred in his own spinoff movies thanks to his irresistible fluffiness and charm.
Maru from YouTube – This famous Scottish Fold became an internet sensation in 2007 through videos showcasing his fluffy roundness and playful personality. Maru’s YouTube channel now has over 400 million views.
Grumpy Cat meme – Her permanent grumpy expression captivated the internet. This Snowshoe mix named Tardar Sauce became a viral meme in 2012 with captions reflecting her displeasure about various topics.
Lil Bub – Known as the “perma-kitten”, Lil Bub was a celebrity cat who appeared on TV shows, merchandise, and even collaborated on a science book. Her extra toes, stubby legs, and wide-eyed gaze solidified her status as an internet darling.
Fluffy cats continue to melt hearts and capture imaginations across pop culture for their cuddly, oversized appearance. Whether real or animated, their larger-than-life fluffiness provides enduring appeal and entertainment.
The Appeal of Fluffiness
Fluffy cats are adored by many people for their soft, plush coats. Their fluffiness gives them an endearing appearance that many find irresistibly cute and cuddly. As one article notes, “their soft and tactile fur can be comforting and soothing to touch, which can evoke positive emotions and reduce stress.” The tactile experience of petting a fluffy cat can release oxytocin, providing a pleasurable bonding experience.
Additionally, some research suggests that the baby-like features of fluffy cats, such as their large eyes, appeal to our innate caregiving instincts. Their fluffiness adds an element of cuteness and vulnerability that brings out our protective instincts. As the article points out, “cats give us attention, relieve our loneliness, provide comfort, fun, and play, affection, and special unique bonds.” Fluffy coats enhance these positive qualities.
Ultimately, fluffiness is an aesthetic trait that amplifies the positive emotional benefits of cat companionship. The soft texture and baby-like appearance taps into our affinity for cuteness and desire for tactile stimulation. For cat lovers, the appeal of fluffy coats is multi-sensory – visual, tactile, and emotional.
Fluffy Cats are Mammals
Fluffy coats do not change the mammal classification of cats. Domestic cats belong to the Felidae family, making them mammals scientifically (Wikipedia, 2022). A fluffy coat is simply a physical trait within some cat breeds and does not alter their genetic make-up or species classification in any way. Fluffiness refers to the soft, long fur that makes certain cats appear extra plush. However, having fluffy fur versus short fur does not impact the biology or taxonomy of domestic cats.
All domestic cat breeds, whether they have a fluffy coat or not, are in the Felis genus of mammals (Northhampton Vets, 2022). Their body structure, reproductive system, and other anatomical features clearly identify them as mammals. The fluffiness of their coat is an external physical trait only. So while fluffy cats may appear extra cute and cuddly compared to their short-haired counterparts, they remain biologically mammalian in all respects.
