Veterinarians across South Florida are warning that a highly contagious cat virus once thought to be mostly a kitten problem is now sickening adult cats and, in some cases, killing them. Shelters and county animal control agencies have tightened quarantine rules, upgraded cleaning routines and expanded vaccination outreach as clinic teams scramble to contain new clusters. Pet owners are being urged to keep any sick cats separated from other animals and call their veterinarian right away.
Local veterinarians told WPBF that test results point to feline panleukopenia virus, also known as feline parvovirus, and that clinics in southern Palm Beach County have seen multiple severe cases. Dr. Kathleen Woodie told the station that some adult cats have died, and the Humane Society of St. Lucie County has reported both young and older cats getting sick. County animal care officials say they are taking extra steps to contain the virus and are asking owners to double check vaccine records and keep pets away from community cats.
How the virus affects cats
Feline panleukopenia targets rapidly dividing cells in the intestines and bone marrow and can cause severe vomiting, bloody diarrhea, loss of appetite, weight loss and profound lethargy, according to the Merck Veterinary Manual. Kittens remain at highest risk, but unvaccinated or immunocompromised adult cats can also become critically ill. Treatment focuses on intensive supportive care, and even survivors may need extended recovery time.
