Miliary dermatitis
Miliary dermatitis is a common reaction pattern in cats characterised by numerous small crusty bumps over the skin, especially along the back and neck, that feel like millet seeds. It is a sign rather than a specific disease, most often caused by flea allergy. Affected cats are usually itchy and over-groom. Successful treatment depends on finding and addressing the underlying cause, with flea control being the most important step.
