The nonprofit Fish & Wildlife Foundation of Florida has announced a $150,000 grant to the Florida Fish and Wildlife Conservation Commission (FWC) to research the cause of a debilitating neuromuscular disorder afflicting Florida’s panthers and bobcats.

FWC Biologist and Law Enforcement Staff, along with citizen scientists, continue to assist with submitting sightings and collecting samples from wild felids to learn more about the prevalence of feline leukomyelopathy (FLM). Since 13 January 2020, we have collected samples from 8 additional bobcats from across portions of central and southwest Florida. Most of these were road mortalities; some were injured bobcats that were brought to rehab facilities for care. Two of the 8 bobcats sampled have been confirmed as having FLM. This brings the total documented cases of FLM to 8 (2 Florida panthers and 6 bobcats). This neuromuscular disorder has now been documented in Collier, Charlotte, Pasco, and Alachua counties. The previous update erroneously included a bobcat FLM case in Hillsborough County. While this animal was euthanized in Hillsborough County, the bobcat was captured in Pasco County. FWC staff continues to collaborate with experts to determine a cause of this disorder.

The FWC continues to investigate the neurological condition, which we have termed feline leukomyelopathy (FLM), in Florida panthers and bobcats. Thanks to reports from the public, veterinarians, and biologists the FWC has determined the condition is more widely distributed than originally believed. FLM has been confirmed in a bobcat from Alachua County, and the Florida Department of Agriculture and Consumer Services has confirmed FLM in a bobcat from Hillsborough County. Another bobcat from Collier County also has FLM and, as expected, necropsy results from the UF College of Veterinary Medicine confirmed FLM in FP256. This brings the total number of confirmed cases to 6 (two panthers and four bobcats). The FWC is continuing to investigate this mystery and no possible causes have been ruled out.

The FWC continues to investigate a disorder detected in some Florida panthers and bobcats. As part of the investigation, the FWC and our partners are caring for two kittens of an affected female panther (FP256) that was euthanized due to the severity of her condition.
We appreciate the support of the public and their concern for these kittens, who recently received their final examinations in a series of kitten checkups. While veterinarians cannot predict to what degree the kittens may become affected, they are currently active, playful, and healthy overall.

In July 2019, the FWC viewed video footage from a trail camera showing a female Florida panther (FP256) in Collier County exhibiting symptoms associated with this condition. The panther had young kittens that likely would not have survived in the wild. FWC staff removed the kittens for observation and testing. Monitoring of these kittens as they age may provide valuable information pertaining to the cause of this condition.
FWC trail cameras subsequently documented that the adult female panther’s health was deteriorating, and in October 2019, the decision was made to remove her from the wild. After a thorough examination the decision was made to humanely euthanize the panther due to the animal’s poor condition and the unlikelihood of recovery or improvement. The panther underwent complete necropsy, and the results of extensive diagnostic testing are pending.
