Cat Skin Problems: Common Issues and When to Worry

Cats hide discomfort well, so skin problems often show up as subtle changes in coat, behaviour or grooming long before you spot a visible lesion. Here are the most common cat skin problems and the signs worth worrying about.

Flea allergy dermatitis

The single most common cause of itchy skin in cats. Even one flea bite can trigger scabby bumps along the back and tail base. Indoor cats are not safe, fleas hitchhike on clothing and other pets.

Overgrooming and bald patches

Symmetrical hair loss on the belly or inner thighs usually means stress, allergies or pain. Cats groom out of self-soothing, so the cause is often not on the skin itself.

Ringworm

Circular patches of hair loss with flaky, broken hairs. Highly contagious to other pets and to humans, especially children. Needs a vet diagnosis and antifungal treatment.

Feline acne

Black specks or small bumps on the chin, often mistaken for dirt. Plastic food bowls are a common trigger, switch to ceramic or stainless steel and clean daily.

Ear mites

Dark, coffee-ground debris in the ears, head shaking and scratching. Common in kittens and outdoor cats. Treated with prescription ear drops.

Abscesses from bites

A hot, swollen lump, often on the face, shoulders or tail base, usually from a cat fight. These can rupture and become infected fast. Vet visit needed.

When to worry

• Any wound that's hot, swollen or smells
• Sudden hair loss, especially in patches
• Yellow crusts, bleeding or pus
• Your cat is lethargic, off food, or hiding more than usual
• Skin changes that don't improve in 3–4 days
