Demon This is a photo of our grandcat Demon. His name really fits him. (Note: Demon is the only surviving kitten from MaMa's two litters. He has tested negative for feline leukemia. We are thrilled. We believe the mother passed on the virus to the kittens. Somehow, Demon must have been able to fight off the virus. The mother cat still appears healthy as of June 2003. We think she must have been able to fight off the virus too. All of our other cats that were exposed have tested negative.) UPDATE: Much to our surprise Demon became ill in August 2005. The diagnosis was feline leukemia and we lost him on August 13, 2005. We are at a loss to explain this since he tested negative, was vaccinated regularly, and was an inside cat. We'll always miss him.
