If your Norwegian Forest cat has tested positive for the FeLV or Feline Leukemia Virus then his overall health will be at risk due to the affects of the disease. For instance, a FeLV positive cat has a compromised immune system making him more likely to contract other diseases and illnesses. Because the virus can be spread through mucus, blood, saliva, and even through mutual grooming or fighting your cat may also be at risk of spreading the disease to other cats. It’s important to keep your FeLV cat in a controlled environment away from other cats in order to protect him from outside illnesses. Keeping him in a safe location can also help prevent the accidental spread of the disease from your cat to another cat. You should take your Norwegian Forest cat in for routine vet check-ups and monitor his health closely. For more suggestions, please talk with your veterinary clinic Isle of Palms, SC.
