I too had a leukemia positive cat. You would never know he had it until he started getting sick all the time from his immune system being suppressed by the leukemia. And you're right, nobody would take him. He, too, was a stray and I thought he would be better off someplace that knew about this disease. I was wrong. I'm glad nobody would accept him b/c then I kept him and he gave me such great joy. Unfortunately, he was only with me 2 years after being diagnosed. I'm glad you had the chance to enjoy Leo for as long as you did. They are special babies. I'm glad Leo was finally brought in and given the love he deserved. Thank you for being kind enough to keep him and give him a life of love. Congrats on COTD Leo boy.
