Feline leukemia (FeLV) is a virus that can cause serious health issues and may lead to death. Your cat may be have been exposed when a vaccination lapsed or she had the disease before you adopted her. If your cat is FeLV-positive, keep her inside and away from other cats so to avoid further transmission. This disease is not contagious to dogs or humans. You will need to deal with weight loss and secondary infections under a medical professional’s guidance. This may include special diets and nutritional supplements, antibiotics, blood transfusions or even IV fluid treatment. Most cats who are infected with FeLV will die from a related condition within two or three years after exposure but can live relatively normal lives during this time. Make sure any companion cats are vaccinated regularly for FeLV exposure. They should be tested before vaccination to make sure they haven’t already been exposed.
