I heard they will only do a blood test to see if my cat has feline Leukemia because he an indoor cat. I wanted a feline leukemia needle for my Joey but wouldn't do it because he is an indoor cat. I guess I would have to get a blood test to see if he has the disease. Would you recommend getting a blood test for my cat since he was around a cat that had Feline Leukemia. Please let me know. Thanks!!
