Will someone PLEASE tell me how Edgar could have contracted this disease? Edgar is a Persian, about 10 years old, that I rescued from a high-kill shelter in October, 2004. He kept being returned to the shelter for one reason or another and I took him home and promised him he would never have to go back there again. I had him tested for FeLV, which was negative, before I introduced him to my other cats at home. My only mistake was that I did not have him vaccinated (even though I thought I did). At least I can't find any record that I did--and I always have my cats vaccinated. I have about nine other cats at home with him--ALL have been tested and vaccinated for FeLV (I double-checked all their records today). The vet says that one of my other cats must have given it to him, but I can't see how. Edgar has had absolutely NO contact with any of my outside cats who have also been tested and vaccinated. I hate to even say this, but could he have contracted it somehow from the vet's office? (I had to have him shaved last summer.) I feel so bad for Edgar because I promised him a good life and now it seems he has very little time left, perhaps days. This also seemed to have come out of the blue--does leukemia strike this fast? Anyone have any ideas? I know I'm losing Edgar--I'm so afraid for all my other cats now.
