Why Does My Cat Eat My Other Cat’s Whiskers: Understanding Feline Behavior

Cats are fascinating creatures that have unique behaviors that can sometimes be puzzling to their owners. One such behavior is when a cat eats another cat’s whiskers. This behavior can be concerning to pet owners who may wonder if their cat is experiencing a medical issue or if there is an underlying behavioral problem. In this article, we will explore some of the reasons why cats eat each other’s whiskers and what you can do to prevent it.

One of the most common reasons why cats eat each other’s whiskers is due to excessive grooming. Cats are fastidious creatures that spend a significant amount of time grooming themselves and each other. However, sometimes this grooming can become a little too aggressive, and cats may end up biting off each other’s whiskers. Additionally, young cats and kittens tend to be more excitable, which can lead to rough play that results in whisker eating.

While excessive grooming is the most common reason for whisker eating, there are other potential causes as well. Medical conditions such as pica, which is a condition where cats crave non-food items, or dental issues that cause discomfort can also lead to whisker eating. In the next sections, we will explore these causes in more detail and provide tips on how to prevent this behavior.

Key Takeaways

  • Cats may eat each other’s whiskers due to excessive grooming or rough play.
  • Medical conditions such as pica or dental issues can also cause whisker eating.
  • To prevent whisker eating, provide your cats with plenty of toys, monitor their behavior, and seek veterinary care if necessary.

Causes of Whisker Eating

Whisker eating is a common behavior in cats, and it can be caused by a variety of factors. In this section, we will explore some of the most common causes of whisker eating in cats.

Dominance and Territory

Cats are territorial animals, and they may engage in behaviors that assert their dominance over other cats in the household. Eating the whiskers of another cat can be a way for a dominant cat to show its superiority over a subordinate cat. This behavior is more common in multi-cat households, where cats may compete for resources such as food, water, and litter boxes.

Stress and Anxiety

Stress and anxiety can also cause cats to engage in whisker eating. Cats that are stressed or anxious may engage in compulsive grooming behaviors, which can sometimes escalate to over-grooming and whisker eating. Cats that are experiencing stress or anxiety may also exhibit other symptoms, such as hiding, avoiding interaction, or urinating outside the litter box.

To reduce stress and anxiety in cats, it is important to provide a calm and stable environment. This can be achieved by providing plenty of hiding places, vertical spaces, and resources such as food, water, and litter boxes. It may also be helpful to provide your cat with toys and activities that encourage play and exercise.

In conclusion, whisker eating in cats can be caused by a variety of factors, including dominance and territory issues, as well as stress and anxiety. By understanding the underlying causes of this behavior, cat owners can take steps to reduce its occurrence and provide a more comfortable and stress-free environment for their feline companions.

Medical Conditions

Cats may eat other cats’ whiskers due to medical conditions. Here are some possible medical conditions that may cause this behavior:

Dental Problems

Dental problems can cause cats to chew on things they shouldn’t, including other cats’ whiskers. If a cat’s teeth are painful or uncomfortable, they may seek relief by chewing on something. If your cat is eating your other cat’s whiskers, it’s possible that they are experiencing dental pain or discomfort. Other signs of dental problems in cats include bad breath, drooling, and difficulty eating.

Feline Acne

Feline acne is a common skin condition that affects cats. It’s caused by clogged hair follicles on the chin and can cause redness, inflammation, and even infection. Cats with feline acne may be more prone to chewing on things, including other cats’ whiskers. If your cat has feline acne, it’s important to work with your veterinarian to manage the condition and prevent it from getting worse.


Hyperthyroidism is a condition in which a cat’s thyroid gland produces too much thyroid hormone. This can cause a variety of symptoms, including increased appetite, weight loss, and behavioral changes. Cats with hyperthyroidism may be more likely to chew on things they shouldn’t, including other cats’ whiskers. If you suspect your cat has hyperthyroidism, it’s important to have them evaluated by a veterinarian and treated appropriately.

In conclusion, if your cat is eating your other cat’s whiskers, it’s important to consider possible medical conditions as a potential cause. Dental problems, feline acne, and hyperthyroidism are just a few of the conditions that may contribute to this behavior. If you’re concerned about your cat’s health or behavior, it’s always best to consult with your veterinarian.

Preventing Whisker Eating

If you have noticed your cat eating your other cat’s whiskers, there are ways to prevent this behavior. Here are some tips to help you prevent your cat from eating other cat’s whiskers.

Feeding Separately

It’s important to feed your cats separately to avoid competition for food. This can help reduce stress and prevent your cats from becoming aggressive towards each other. You can also try feeding your cats at different times or in different rooms to prevent them from getting too close to each other’s food.

Providing Enough Resources

Make sure your cats have enough resources, such as food, water, and litter boxes, to prevent competition and reduce stress. You can also try providing multiple food and water dishes, as well as multiple litter boxes, to prevent your cats from getting too close to each other’s resources.

Reducing Stress

Stress can be a major factor in your cat’s behavior. To reduce stress, you can try providing your cats with plenty of toys and playtime. You can also try providing your cats with a quiet, comfortable space to retreat to when they need a break from each other.

In conclusion, preventing your cat from eating other cat’s whiskers is possible by feeding them separately, providing enough resources, and reducing stress. By following these tips, you can help ensure that your cats live in a peaceful and stress-free environment.


In conclusion, there are several reasons why your cat might be eating your other cat’s whiskers. It could be due to excessive grooming, rough play, or even a sign of dominance. As a pet owner, it is important to monitor your cats’ behavior and intervene if necessary.

If you notice that your cats are engaging in rough play or aggressive grooming, it may be helpful to provide them with more toys and activities to keep them occupied. Additionally, if you have multiple cats, it may be helpful to provide them with separate feeding areas to prevent competition and dominance behaviors.

It is also important to note that while cats’ whiskers may grow back, it is still important to prevent your cats from chewing on each other’s whiskers. Whiskers play an important role in helping cats navigate their environment and maintain their balance.

Overall, if you are concerned about your cats’ behavior or health, it is always best to consult with a veterinarian or animal behaviorist. With proper care and attention, you can help ensure that your cats live happy and healthy lives.
