Miliary dermatitis is a common skin condition that affects cats. It is often due to insect allergies (fleas, mosquitoes, and flies), food allergies, and contact allergies. Other conditions that cause miliary dermatitis include: ear mites, scabies (Notoedres), bacterial infections, drug reactions, and ringworm.

The most common skin lesions associated with miliary dermatitis are papules (very small bumps) and crusts. Often, the crusts are present but not easily seen. They can be felt by rolling the animal’s skin between the thumb and first two fingers. Secondary skin lesions, which include fur loss and skin erosions, result from self-mutilation (licking, scratching, and rubbing).

Effective treatment for miliary dermatitis involves the diagnosis and management of the underlying condition.

Skin scrapings, biopsies, cultures and blood tests are often necessary to diagnose the underlying condition.

Diagnosis and treatment of miliary dermatitis is made by a veterinarian.
