Leon is such a sweet cat with humans and other cats. Outgoing, affectionate and playful , you can't ask for a better friend. He did test positive for FIV but because he's not aggressive he can live with negative cats. FIV (Feline Immunodeficiency Virus) is not a big concern. Given proper care and attention, an FIV+ cat will live the same lifespan as an FIV negative cat. The disease is extremely hard to transmit from cat to cat, requiring direct blood contact (typically from a deep puncture wound). It is not transmissible to humans.
