Pet Cat in Florida Helped Scientists Discover New Virus Strain — and It’s Not the First Time the Feline Has Done It

Cat in Florida Shows Researchers New Virus Strain for Second Time​

A fascinating story emerged from Florida where a cat named Pepper has once again played a crucial role in helping scientists discover a new virus strain. Pepper, a beloved pet belonging to virologist John Lednicky, has proven to be an unconventional yet effective assistant in the world of scientific research.

Pepper’s owner, John Lednicky, works at the University of Florida (UF) College of Public Health and Health Professions. The 7-year-old black shorthair cat has a habit of bringing home rodents that it catches in the wild. Lednicky, seizing the opportunity, takes these carcasses to his laboratory for further investigation.

Recently, Pepper brought home the carcass of an Everglades short-tailed shrew. Upon examination at the lab, Lednicky and his team made an intriguing discovery – the rodent was carrying a new strain of orthoreovirus. This virus is known to be capable of jumping between various species and is commonly found in mammals and birds.

This isn’t the first time Pepper has made headlines for his contributions to scientific research. In 2024, Pepper brought home a rodent that was found to carry a previously unidentified type of jeilongvirus, a virus not previously documented in North America. Belonging to the same family as viruses that cause measles and mumps, this new strain raised concerns about potential transmission to humans.

Lednicky emphasised the importance of paying attention to orthoreoviruses and having efficient detection methods in place. While the specific strain of orthoreovirus found may not pose an immediate threat to humans, UF’s Ph.D. candidate Emily DeRuyter highlighted that certain forms of orthoreoviruses have been linked to respiratory, central nervous system, and gastrointestinal diseases.

Despite his adventures in the great outdoors and encounters with potentially infectious rodents, Pepper is reported to be in good health. The university confirmed that Pepper has not shown any signs of illness and is likely to continue aiding in scientific discoveries through his unique specimen collection methods.

Lednicky’s approach to testing rodents brought in by Pepper reflects an opportunistic stance towards scientific exploration. Instead of simply disposing of dead animals, Lednicky seizes the opportunity to extract valuable information through laboratory testing. This approach has proven to be fruitful, shedding light on previously unknown virus strains and contributing to a better understanding of disease transmission.

The collaborative effort between Pepper and Lednicky serves a dual purpose – studying the transmission of the mule deerpox virus, an infectious agent that primarily affects deer. By utilising Pepper’s specimen collection skills, Lednicky’s work continues to uncover valuable insights into infectious diseases and their potential impact on wildlife and human health.

Pepper’s unique role in scientific discovery exemplifies the importance of observing the world around us and utilising unexpected sources in the pursuit of knowledge. This heartwarming tale of a feline companion aiding in groundbreaking research serves as a reminder of the diverse ways in which animals can contribute to our understanding of the world.
