Two of my cats Meeshe and Muskrat (both rescues) are FeLV+. I have had Meeshe for about 4 years and he is otherwise healthy as can be. So is Muskrat. They are separated from my other 4 as a precaution, even though my others (strictly indoors) have been vaccinated.

I would just like to say that from the experience I've had with my two, FeLV is NOT a certain death sentence by any stretch.
