As we learn more about Feline Leukemia Virus (FeLV), we know it’s a very complicated virus and testing for it is not always straightforward. A cat can test negative today and positive next month, or positive today and negative next month. And, depending on the test used and whether whole blood or serum is used, different test results can be obtained. 

The more we learn about Feline Immunodeficiency Virus (FIV), the more of a non issue it is becoming. So much so that the vaccine is no longer available in the United States. 

It’s no wonder shelter management is questioning if it makes sense to test every cat. Go to “Why are some shelters no longer testing all cats for FeLV and FIV?” to learn more about the rationale on why shelters are no longer testing every cat for FeLV and FIV.
