The FeLV virus (also known as the Feline Leukemia Virus) is a type of cancer or disease that can affect cats of all ages and breeds including the Ocicat breed. FeLV can cause anemia, lymphoma, and a suppressed immune system in cats. The virus is not contagious to other animals or people. There is no cure for FeLV and most treatment options are for the purpose of prolonging your cat’s quality of life. It’s important to have your Ocicat tested routinely for FeLV even if a diagnosis has already been made. There are levels or degrees of the illness. Your cat may test FeLV positive, but maintain normal levels for years before any symptoms of the disease appear. In addition, your cat may show FeLV positive and simply be a carrier and not actually infected with the disease. Talk with your best pet clinic Plano, TX about medication and long-term care for your Ocicat.
