Cats that are exposed to or have tested positive for the Feline Leukemia Virus (FeLV) are much more susceptible to additional illnesses and conditions because of their weakened immune system. If your British Longhair cat has been diagnosed with FeLV then you will need to keep him separated from healthy cats and ensure he drinks and eats out of his own food and water bowls. Keeping your cat away from other cats can also prevent an unintentional illness. Sometimes healthy cats can carry viruses or illnesses that don’t affect them, but could potentially be fatal to an FeLV cat with an already weakened immune system. Your FeLV positive British Longhair cat may be more prone to developing infections or other diseases such as kidney disease and cancer due to his FeLV condition. For more information about your cat’s health and ways to protect him, give your veterinarian Columbia, MD a call.
