Two of my cats tested postive for leukemia when they were 5 years old. They were also vaccinated for leukemia for the past 3 years but it didn't stop them from getting the disease. I understand the vaccine only 80% effected.Originally Posted by jaycee
you are right, not one place i have read it quotes any sort of studies to support it, but i have read it on many other sites besides that. thanks for posting your information. i will get my kitties vaccinated once after they turn 6 months even though they are indoor kitties but i would want them to be protected in case they ever got out. better safe than sorry.
