South Florida veterinarians are warning cat owners about a concerning change in a highly contagious virus that is now making adult cats seriously ill.Feline panleukopenia virus (FPV), sometimes referred to as feline parvovirus, has traditionally been most dangerous for kittens.

It’s difficult to tell if something is a new strain, because that would mean that something has genetically been altered. Sometimes we just see variants that come through that are stronger; they have what we call more virulence, so that means it has more ability to make animals sick,” she said.Woodie said it’s normal to see a few kittens test positive for the virus, but it’s extremely worrisome to see adult cats becoming sick from the virus. “In the last couple of years, we have not seen this. We have not seen cases specifically where adults are becoming very clinically ill. And we do not have any known cases where we were losing adult animals to this disease,” she said. She told WPBF 25 News this is a huge concern. “When we talk about a shelter situation, this is one of what we call the big bads. These are the things that we’re the most worried about,” Woodie said.

PALM BEACH COUNTY, Fla. —

South Florida veterinarians are warning cat owners about a concerning change in a highly contagious virus that is now making adult cats seriously ill.

Feline panleukopenia virus (FPV), sometimes referred to as feline parvovirus, has traditionally been most dangerous for kittens. However, this season, veterinarians say the virus appears to be affecting adult cats as well.

Dr. Kathleen Woodie, chief of veterinary services for Palm Beach County, said some cases have proven deadly.

“We are seeing adult cats that are not only getting sick from the virus, but we believe that some have actually died from the virus,” she told WPBF.

Woodie said the county has identified multiple cases in the southern part of Palm Beach County involving cats with severe gastrointestinal illness. That means symptoms like vomiting, diarrhea, bloody stool, loss of appetite, weight loss, and lethargy.

“Something has changed. It’s difficult to tell if something is a new strain, because that would mean that something has genetically been altered. Sometimes we just see variants that come through that are stronger; they have what we call more virulence, so that means it has more ability to make animals sick,” she said.
