What is FIV and how is it transmitted? FIV (Feline Immumodeficiency Virus) is a retrovirus in the same family as the human AIDS virus, with a few significant differences. It is estimated that in the United States, 2% of cats are infected with the FIV virus. http://cats.about.com/cs/healthissues/a/fiv_in_cats.htm.
How Feline Immunodeficiency Virus Is Transmitted. Cats can contract FIV in two significant ways. The most common method of transmission is when an infected cat bites another cat and passes the virus in saliva to the other cat's bloodstream. The second, but less common, transmission route is when an infected female cat gives birth to a litter of kittens.
