Pawsitively Strange: Why Do Cats Like Earwax?

Many cat owners have witnessed their furry companions engage in the peculiar behavior of licking and nibbling on earwax. While this habit may seem strange and even a little gross, there are several reasons why cats might find earwax so irresistible.

Why Do Felines Find Earwax So Irresistible?

The Scent of Animal Proteins

Cats are obligate carnivores, meaning they require a diet rich in animal-based proteins for optimal health. Earwax contains dead skin cells, fatty acids, and cholesterol, which are all components of animal proteins. To a cat's sensitive nose, the scent of these proteins is incredibly enticing, triggering a primal instinct to consume them.

Evolutionary Origins

The roots of this behavior may lie in the ancestral history of cats. Wild cats are known to scavenge for food, including sources rich in protein and fat. Earwax, especially from prey animals, might have offered valuable nutrients in times of scarcity. This evolutionary memory could be driving the behavior in domesticated cats, even though they have access to readily available food.

A Grooming Instinct

In cat colonies, grooming plays a vital role in social bonding and maintaining hygiene. Allogrooming, the act of grooming another cat, helps to strengthen relationships, remove parasites, and clean hard-to-reach areas like the ears. When your cat licks your ears, they might be exhibiting this natural grooming instinct, even though you're not a fellow feline.

The Flehmen Response

Some cats may exhibit the Flehmen response when encountering earwax. This involves curling the upper lip and exposing the Jacobson's organ, a specialized organ in the roof of the mouth responsible for detecting pheromones and other odorants. By performing the Flehmen response, your cat is able to better analyze the scent of the earwax and determine its significance.

A Source of Vitamin B12

Earwax contains small amounts of vitamin B12, which is essential for cats. While regular cat food should provide adequate B12, some cats may seek out additional sources, particularly if they have a deficiency.

Simple Curiosity

Cats are naturally curious creatures and will often investigate anything that smells or feels unusual. Earwax, with its unique scent and texture, can be quite intriguing to them. Licking it is simply their way of exploring and learning about the world around them.

Is it Harmful for Cats to Eat Earwax?

In general, occasional earwax consumption isn't harmful to your feline friend. However, there are situations where it's best to discourage the behavior:

Excessive earwax: If your cat has an ear infection or ear mites, the excess earwax may contain bacteria or parasites that could make them sick.

Unsanitary sources: Letting your cat lick earwax-laden cotton swabs or Q-tips from the trash can expose them to harmful bacteria and parasites.

Compulsive behavior: If your cat becomes obsessed with earwax, licking it excessively, it could lead to skin irritation or hair loss.

What to Do if Your Cat Likes Earwax

While you can't entirely eliminate your cat's interest in earwax, you can take steps to manage the behavior:


Clean your ears regularly: This reduces the buildup of earwax, making it less appealing to your cat.

Keep your cat's ears clean: Regularly check your cat's ears for excessive wax or signs of infection. Consult your veterinarian for proper cleaning solutions and techniques.

Distraction and Positive Reinforcement:

Offer alternative objects to lick: Provide your cat with catnip toys or chew toys to redirect their attention.

Reward positive behavior: When your cat engages in alternative activities like playing or grooming themselves, praise them and offer treats.


Bitter apple spray: Apply a small amount of bitter apple spray on your ears to discourage licking. However, use this sparingly and under supervision, as some cats may find the taste repulsive.

Never yell or punish your cat. This will only create fear and anxiety and worsen the behavior.

If you're concerned about your cat's earwax obsession or their overall health, consult your veterinarian to rule out any underlying medical issues.
