Feline Leukemia Virus (FeLV) is the second leading cause of death in cats, killing 85% of infected cats within three years of diagnosis. The virus affects the cat’s blood, causing various blood diseases. It also suppresses the cat’s immune system, making it harder to protect against infection by bacteria, viruses or fungi found in our everyday environment that wouldn’t affect healthy cats.
However, feline leukemia does not have to be a death sentence; about 70% of cats who encounter the virus are able to resist infection or eliminate the virus on their own.
In a recent article on Answers.com, I explained the symptoms of FeLV, how it is diagnosed and treated, and how it can be prevented.
