Feline immunodeficiency virus (FIV) is a type of virus called a retrovirus. It is in the same family as feline leukemia virus (FeLV) and human immunodeficiency virus (HIV, the virus that causes AIDS). It attacks the immune system, and as a result, the cat is unable to fight off various infections and cancers. Approximately 2.5% of cats in the United States are infected with FIV.
Feline FIV. (Feline Immunodeficiency Virus) Feline FIV (feline immunodeficiency virus) belongs to the same family of viruses as HIV (human immunodeficiency virus). It produces a disease in felines similar to AIDS in humans, and is often transmitted through cat bites during fighting. This family of viruses, known as lentiviruses (or slow virus) is species-specific. As the names imply, FIV is specific to cats, HIV is specific to people.
