What you need to know about FeLV

Feline leukemia virus (FeLV) is a disease affecting cats only and is transmitted from cat to cat through saliva, blood, urine and feces. The Virus causes anemia or lymphoma and can suppress the immune system and lead to deadly infection.
Exposure to the virus isn’t always deadly, as many cats are resistant or eliminate the virus on their own.  And there’s more good news as there has been a 25% decline in FeLV over the last 25 years because of vaccines and preventative testing.

Who’s at Risk?

  1. Multi-cat homes that share food, water and litter boxes
  2. Outdoor cats
  3. Shelter cats
  4. Kittens born to infected cats or those living near outdoor cats
  5. Feral cats

It can take up to 60 days for a Cat to be infected once exposed to the virus. Some cats can clear the virus if they have a strong immune system. Testing may need to be done more than once to confirm the infection due to the opportunity to surpress the infection.
