Hair loss in cats isn't just a cosmetic issue—bald spots can indicate underlying health problems.
Whether it's allergies, parasites, or stress, there are many reasons why your cat might suddenly start losing hair.
Possible causes of hair loss in cats
1. Parasites such as fleas and mites
Fleas, lice, or mites cause intense itching, leading to excessive scratching and licking—and eventually bald patches, often on the neck, belly, or around the tail.
2. Allergies (food, environment, flea bites)
Cats can be sensitive to certain proteins in food, dust mites, pollen, or flea saliva. Typical symptoms include itchy, inflamed skin and simultaneous hair loss.
3. Ringworm (dermatophytosis)
Fungal infections are highly contagious and manifest as round, bald patches with flaking skin. Young or weakened cats are particularly susceptible to this condition.
4. Hormonal disorders
Problems with the thyroid or adrenal glands can disrupt the natural shedding cycle and cause diffuse hair loss—often without itching.
5. Stress or boredom
Psychological stress (such as moving, new pets, or a lack of stimulation) can lead to compulsive licking (psychogenic lick alopecia)—especially on the belly and hind legs.
When should you take your pet to the vet?
A visit to the veterinarian is strongly recommended if:
-
The bald spots are getting bigger or spreading
-
The cat is constantly scratching or licking itself
-
the skin is red, flaky, or inflamed
-
Additional symptoms include diarrhea, vomiting, or behavioral changes
