CAN A CAT EXPOSED TO THE RETROVIRUS GIVE ANOTHER CAT FELINE LEUKEMIA?
Answer – The answer to that can be complicated. I’ll explain it the best I can. If the cat is carrying feline leukemia and is actively shedding it (tests positive on a blood test), then he can give it to another cat, mainly through mutual grooming. It really requires direct contact with saliva to spread, although sharing water bowls or litter boxes may be uncommon ways to spread it. Here’s where it becomes complicated – a cat can test negative for several weeks when first infected.
