Feline Leukemia (FeLV) is a virus that can compromise your cat’s immune system and lead to death. FeLV is transmitted through bodily fluids, most often while grooming or fighting an infected cat. If your cat is infected she will experience fever and lethargy. She will also be susceptible to a number of other infections. You can treat the resulting infections but FeLV is incurable. You will need to keep your cat inside at all times to avoid infecting other cats. Any other cats in your home are at risk too. Infected cats usually die within two years of infection. Fortunately, there is a vaccination to protect your cat from FeLV. Have your cat vaccinated young and continue with all needed booster shots to keep your cat protected throughout her life. Your cat will need periodic blood tests to ensure she hasn’t been infected. For more information, contact your Westminster, CO veterinarian. Visit this website for additional details.
