Keurig has been vaccinated, wormed, spayed/neutered and tested negative for FELV which is all included in the adoption fee. This cat is FIV positive which means that their immune system could become a little weaker than a non FIV cat. FIV cannot be transmitted to humans or dogs and is only transmitted to other cats through mating and deep puncture wounds. It is not spread via grooming or sharing food bowls or litterboxes. So as long as they like other cats they can be adopted to a home with them whether the existing cats are FIV or not. FIV+ cats live long happy lives and usually live just as long as non FIV cats.
