I just adopted a 2 mo. old kitten from the animal shelter...3 days later she is dead from cat fever. What do I need to do to be sure a new kitten does not get the same disease? I was told to disinfect everything, but what about furniture? At what age do their vaccinations make them immune? How soon is it safe to get another one? And last, but not least, where is the safest place to go to adopt? Please help...I really want another one soon....and so does my dog! Thanks for any help. Charlene
