I had 12 cats when I found out one was positive and had been with everyone else for months. I spent a lot of money retesting and everyone else has remained negative. I then brought in another positive (on purpose) because I am not worried about my cats catching the leukemia. The negative cats do need to be vaccinated. It doesn't 'hurt' if you vaccinate someone and they later turn out to be positive. But unless someone gets sick I wouldn't test them again. All my cats mix freely together, eat together, use same litters, etc.... tonya

The infected cat was not outwardly sick and di not socialize with the other cats, however they used same litter boxes and ate from same dishes. Any help would be greatly appreciated. All cats are close to same age, different litters, aquired at the same time.
