Purdue University’s College of Veterinary Medicine conducted a long-term study in cat shelters
and drew two conclusions: FIV-positive cats can live with FIV-negative
cats and not infect the FIV-negative cats during normal day-to-day
interaction; and mother cats infected with FIV don’t pass the virus on
to their kittens. The study was conducted by Dr. Annette L. Litster of
the college’s Department of Veterinary Clinical Sciences.
