At PetNest Animal Hospital, we believe that awareness and prevention are the most powerful tools in protecting your cat from serious illnesses. Feline Leukemia Virus (FeLV) is an often life-threatening virus that affects approximately 2-3% of cats in the US. Knowing which cats are most vulnerable, what symptoms to watch for, and when to test and vaccinate can drastically lower the risk to your pet’s health.
Which Cats Are Most at Risk of Feline Leukemia?
While any cat can contract FeLV if they come into contact with the bodily fluids of an infected feline, some are more susceptible than others. The highest risk groups for Feline Leukemia include:
- Kittens because their immune systems are not fully developed
- Outdoor Cats because they are more likely to come into contact with infected strays
- Cats in Multi-Cat Homes with other felines that go outside, even if they are indoor only
- Cats with Unknown Medical Histories including rescues or newly adopted pets
If your cat falls into any of these categories, discuss preventive options for Feline Leukemia with your veterinarian.
Feline Leukemia Symptoms to Watch For
FeLV often progresses quietly, with symptoms only appearing after the disease has advanced. This progression can take months or even years. When the signs of Feline Leukemia do emerge, they may include:
- Persistent fever or diarrhea
- Weight loss and reduced appetite
- Pale gums
- Enlarged lymph nodes
- Recurrent respiratory or urinary infections
- Deteriorating coat condition
Since these symptoms can overlap with other illnesses, a veterinary evaluation with testing is the only way to identify Feline Leukemia.
FeLV Vaccination and Testing Protocols
Feline Leukemia can be identified through a simple blood test, which is especially important when:
- Introducing a new cat into your household
- Managing cats that go outdoors or interact with strays
- Your cat shows unexplained symptoms
Regular FeLV screenings during annual exams are recommended for at-risk cats. If your feline does test positive, a secondary screening is usually performed to confirm diagnosis.
For cats that don’t already have Feline Leukemia, there is a FeLV vaccine. This vaccination is strongly encouraged for at-risk cats, but can be beneficial for any cat. After all, even indoor cats can escape and end up interacting with an infected cat. Being vaccinated against Feline Leukemia significantly lowers the risk of infection and helps contain the virus in the broader feline population.
