What if my cat has no symptoms but tests positive?

Carriers can now live normal lives. Before scientists could vaccinate against FeLV, most veterinarians recommended euthanasia for FeLV-positive cats whether or not they had symptoms. This policy was meant to control the spread of the disease. Now that we have a vaccine, owners have the option to keep their infected cats if the cats are not suffering. If making such a decision, an owner must isolate the infected cat as much as possible because carriers can still pass the disease to unvaccinated cats.
