Most veterinary hospitals are equipped for feline leukemia virus (FeLV) testing. The test is well worth the money and is used to diagnose FeLV-related illnesses, detect subclinical infections, and identify FeLV infections in multicat households (and catteries). It is highly advisable to test any cat or kitten before introducing him or her into a new home. Cats and kittens should also be tested for feline leukemia before vaccinations are given.
In order to test for feline leukemia, a small amount of blood is taken from the cat.
Testing for feline leukemia is safe and inexpensive. Due to the nature of the disease, all cats should be tested.
