So has anyone run into this. I have a 7 year old kitty who has only had 2 feline leukemia shots in her life. The first one when she was about 4 months the 2nd being the follow up shot. The leg she got the 2nd shot in she couldn't walk for about 2 days after maybe 12 hours after getting the shot. I thought she had been stepped on or hit by a car. She cried in pain all night. Rushed to the vet the next morning first thing. They took an x ray saw nothing when the vet realized it was the leg he had given her her shot in. Since he has not given her the shot. I worry a little that she could contract Leukemia but thank goodness she is not a fighter at all (except with her brother). Has anyone had something like this?
