All cats should get this important test early in their lives (which also tests for Feline Immunodeficeincy Virus). Cats that go outdoors regularly or occasionally should also be tested periodically because their risk of exposure is greater. Also, if a new cat is being introduced into the house hold, the new cat should be tested, as well as the family cats if they have not been tested before. It is also recommended that your cat receives this test from time to time even if he or she has tested negative in the past.
