The reasons why cats like to eat their own hair balls:

1. Clean their hair.

Cats love cleanliness very much. Most cats attach great importance to their hair and regard this action as a sacred ritual. By licking the hair, the dust and dirt on the hair can be removed. This is one of the reasons why cats can stay very clean without taking a bath for a long time.

2. Regulate body temperature.

Cats like to lick their fur because they are affected by the changes in the seasons. In the winter, licking your hair can make your hair fluffy and create an air layer to keep you warm. In summer, they cool themselves by wetting their fur and licking their paws.

When cats are bathed in sunlight, their hair will produce a vitamin called vitamin D. Basking in the sun will cause these nutrients to attach to the hair, and the cat can quickly absorb and replenish the nutrients into the body through licking.

4. Remove odor.

Before cats were domesticated by humans, they relied on hunting in the wild. When hunting, they hide their scent. It will lick its hair to remove the remaining smell on its body to hide itself.

Although cats today no longer need to hunt, this genetic instinct remains in them.

Cats lick their fur and have a massage effect. Licking their fur can relax them and soothe their mood. This helps them digest and reduces the risk of depression.
