What is commonly referred to as Feline AIDS is actually Feline Immunodeficiency Virus (FIV). FIV affects only cats and is not harmful to any other species. Once infected, a cat carries the virus for life and may pass it to other cats through direct contact with blood and saliva. FIV attacks immune cells, reducing their ability to fight infections. FIV positive cats should remain indoors to prevent acquiring illnesses and they should not be introduced to non-infected cats to prevent the spread of this disease. There is no cure for FIV but many FIV cats lead long, comfortable happy lives.
