IMPORTANT NOTICE

RICHMOND, B.C. — [AUGUST 5, 2026] — Cases of feline panleukopenia (also called feline distemper), have been detected in Metro Vancouver. This is a highly contagious and often fatal viral disease that is especially dangerous to young, unvaccinated cats.

“This is one of the most heartbreaking diseases anyone working in cat rescue can encounter,” said Eyal Lichtmann, chief executive officer of the Regional Animal Protection Society. “Kittens can appear healthy and then deteriorate with frightening speed. Pet guardians are urged to contact their veterinarian to ensure unvaccinated kittens are safe.”

Feline panleukopenia can cause profound lethargy, loss of appetite, fever, vomiting, dehydration and, in some cases, diarrhea or sudden death. The acute illness generally lasts no more than five to seven days, but very young kittens are at especially high risk. The virus can also persist in the environment for up to a year unless surfaces are properly cleaned and treated with an effective parvovirus-killing disinfectant.

There is no medication that directly eliminates the virus. Treatment may require hospitalization, intravenous fluids, medications to control vomiting, antibiotics to address secondary infection, nutritional support and intensive monitoring. Even with aggressive care, survival is not assured.

Vaccination is the most effective protection against feline panleukopenia. The vaccine is included in the standard FVRCP series recommended for kittens and cats. Cats with unknown vaccination histories should be assessed by a veterinarian.

Members of the public should contact a veterinarian immediately if a kitten or cat develops sudden lethargy, loss of appetite, vomiting, fever, severe dehydration or unexplained weakness. Anyone who suspects exposure should telephone the veterinary clinic before arriving so appropriate infection-control measures can be arranged.
