Generally speaking, this is the part of the cat’s glands. Many cats have sparse hair in varying degrees, which is a normal phenomenon.
A cat has glands on both sides of its head, paws, jaws, anal glands, and tail that secrete special flavors. Cats will leave a smell on the things they like, or they will keep rubbing them if they like their owners, so as to swear their sovereignty.
But there may also be pathological hair loss, the most common being ear mites (other ear parasites include Demodex, scabies, etc.) or cat moss.
Ear mites: The ear scabies parasitic on cat ears, which will stimulate the cat ears to secrete dark brown secretions.
Ear mites are easy to diagnose. If you find that your cat has an unpleasant odor, your cat’s ears are often itchy and vibrate, or you scratch with your claws, you should pay attention. .
Cat moss: An itchy fungus that lives in hair follicles and feeds on dead cells. Manifested as round or oval hair loss, accompanied by skin redness, white scaling, small scabs, etc. Contagious.
Meow parents and meow mothers can control the symptoms. If they observe the skin changes of their cats, they can take them to the pet hospital for diagnosis and treatment as soon as possible. If there are multiple cats in the house, be careful to isolate sick cats to prevent mutual infection.
