It is wise, however, to have the test repeated by a different laboratory using a different technique (Western Blot). Mother cats with FIV pass antibody to their kittens whether the kittens become infected or not. So positive test results in kittens do not mean they harbor the virus of FIV.

If the test is still positive at six month, they probably have the disease.
