Fel-O-Vax FIV Vaccine

Fel-O-Vax FIV Vaccine aids in the prevention of feline AIDS.

Feline AIDS is caused by infection with feline immunodeficiency virus (FIV). FIV causes a potentially fatal viral disease that interferes with the immune system of a cat. Infected cats may expose healthy cats with which they come into contact, most often by biting. Outdoor cats are most at-risk. Vaccination is the best way to prevent disease. There is no treatment or cure for an infected cat.
