INHS Wildlife Veterinary Epidemiologist Nohra Mateus-Pinilla and graduate students Shannon Fredebaugh recently published a study that found that even in remote parts of a natural area, cats spread disease to wildlife. Their study, Allerton Park in Monticello, does not have bobcats which strongly suggests feral house cats are responsible for spreading the feline dependent Toxoplasma gondii parasite.  Infection by the parasite causes neurological problems and possible death in humans and other animals. "If one infected cat defecates there, any area can become infected," Fredebaugh said. "It just takes one cat to bring disease to an area."
