Feline AIDS is spread by FIV (Feline Immunodeficiency Virus) most commonly through deep, penetrating bite wounds. FIV cannot be spread to other cats through shared water bowls, food bowls or grooming and feline AIDS is not transmittable to humans. FIV cats may appear healthy and normal for years, especially if they are given a low carbohydrate, hypoallergenic diet and immune support supplements. FIV will eventually compromise a cat’s immune system, making them more susceptible to secondary infections. Many cats can live with FIV for quite some time before it progresses to Feline Acquired Immunodeficiency Syndrome (Feline AIDS). FIV-positive cats can cohabitate safely with FIV-negative cats as long as there are no personality conflicts or territorial behaviors that might cause the cats to fight.
