Why Do Cats Bite Their Nails? 4 Possible Reasons

Cats are known for their meticulous grooming habits, but if you've ever noticed your cat biting and chewing their nails, you might wonder if this behavior is normal. In most cases, it is a part of their regular self-grooming ritual and not a cause for concern. Cats are fastidious creatures, and they constantly clean themselves, which includes nibbling on their claws to keep them in good condition.

In this article, we'll explore why cats chew and bite their nails and provide you with valuable tips to address this behavior. Let's delve into the details!

The 4 Common Reasons Why Cats Bite Their Nails

Normal Grooming

Routine chewing, licking, and pulling on and around the claws are part of your cat's standard self-grooming practice. Since their paws frequently touch the floor, they can accumulate dirt, hair, dust, and debris around their claws. Sometimes, simple licking may not suffice to dislodge these particles, leading your cat to nibble or tug at their claws to free up any stuck debris. Cats' nails consist of multiple layers, and the outer layer may become frayed and damaged. Your cat's chewing behavior often serves the purpose of exposing the cleaner, sharper layer underneath.

Ensure your cat has access to a scratching post or similar surface as they use these to maintain their nail health. Inadequate scratching surfaces might lead to excessive nail chewing.

Behavioral Issues

Occasionally, normal self-grooming can transition into obsessive behavior characterized by excessive licking, scratching, and claw-chewing. This behavior often stems from stress, boredom, or loneliness. In some cases, cats may chew their paws as a self-soothing mechanism when they're anxious or stressed, much like humans biting their nails in similar situations. Identifying the underlying cause of your cat's stress or anxiety is essential to curbing this behavior. It could be as evident as a recent move or the introduction of a new pet, but more subtle causes may require detective work. Spending more interactive time with your cat or providing stimulating toys can help alleviate loneliness and boredom.

Medical Issues

Nail-biting can also be a response to an underlying medical problem. Your cat might have injured themselves on a paw pad, a toe, or broken a claw, leading to discomfort and nail chewing. Alternatively, excessive pulling and chewing could be the cause of the injury itself. Close examination of your cat's paws for signs of injury is necessary, and a vet visit might be required. If there are no apparent signs of injury, an underlying medical condition could be the culprit. Infections, both bacterial and yeast, can prompt cats to lick and pull at their paws. An autoimmune disease called Pemphigus can lead to lesions on the nail beds, triggering excessive claw attention. Ringworm, a fungal infection, can also affect the nails and skin, leading to grooming behavior changes.

Additionally, certain cat breeds might be genetically predisposed to specific conditions, like haircoat disorders and dental diseases, which can indirectly lead to overgrown nails. Cats can also react to household chemicals or detergents, emphasizing the importance of keeping these substances out of your pet's reach.

Nail Problems in Older Cats

Elderly cats require extra attention, including grooming and specialized cat food. Aging cats may develop hormonal imbalances that result in nails that are too thick or brittle. They are also prone to various age-associated conditions such as cognitive decline and tumors. If you find your older cat biting her nails, it's advisable to consult with a vet to address potential age-related issues effectively.

In Conclusion

In a healthy cat, occasional nail biting is generally nothing to worry about. It's merely a part of their self-grooming routine. However, if you notice that this behavior has become unusually frequent or if it's accompanied by signs of pain or discomfort, there might be an underlying medical concern. In such cases, a visit to the veterinarian is the best course of action.

As a cat owner, you are in the best position to notice any changes in your cat's behavior. If you ever have doubts about your cat's well-being, don't hesitate to consult with your veterinarian. Your feline companion's health and happiness are of utmost importance.
