Food hypersensitivity to lamb in a cat.

Abstract

Severe facial pruritus in a cat was caused by food hypersensitivity to lamb. The cat had been fed an exclusive diet of lamb for 2 years after it had been diagnosed to have food hypersensitivity to fish. Signs, including erythema, alopecia, and excoriations of the head and neck, were poorly responsive to corticosteroid administration, but resolved within a few weeks after removal of the suspected allergen.
