As soon as you obtain a new kitten for your home, there is one thing you need to do. Take it to the vet and check it’s health. In the world of kitten health, one of the major concerns is feline leukemia. A full-grown cat who contracts the disease may be capable of living a few months to years, but a newborn kitten may only live a few weeks. It is important to get the kitten checked for such things, for the virus is very contagious, and, if a positive test for the virus does show up, be sure to keep the animal away from any other pets around the household.
