Many diseases affect the skin on the noses of cats. This can include bacterial or fungal infections of the skin, or mites. These diseases may affect the bridge of the nose where there is hair, or the smooth part of the nose, where there is no hair. Often, it is the portion of the nose that has hair that is affected. In the case of systemic diseases like lupus or other autoimmune ailments, the whole muzzle is involved. Some systemic diseases cause the part of the nose where there is no hair to lose its pigment or develop ulcers.

Most of these conditions are more likely to occur in kittens under a year of age, but skin cancers are more likely to occur in older cats.
