Lesions appear as soft, fleshy, freely movable nodules in the skin. They are nonpainful and the cat is generally in good health. These lumps can however become ulcerated and surrounding lymph node (glands) may become enlarged. Most lesions are seen on the head and lower legs.

Surgical removal is the treatment of choice however antituberculosis drugs such as Dapsone and Clofazimine (3mg/kg daily for 6 weeks) may also be effective.
