Cat kills rodent. Cat eats rodent. Cat is exposed to potentially lethal rodenticides. That scenario is increasingly likely for many small wild cat species across the globe, and yet, only a handful of researchers are investigating this underrecognized conservation issue. Thus far, researchers confirmed that one wild cat population has declined from exposure to these poisons. That’s a small bobcat (Lynx rufus) living on Kiawah Island off the South Carolina coast in the U.S., which faces imminent local extinction due to rodenticides. Up until 2019, there was a stable population of these beloved cats, which are considered celebrities there, but that year, three cats died. Among them was a female that bled to death while giving birth. Postmortems revealed concoctions of rodenticides in each of the bobcats’ blood and livers. Over the next four years, there were 12 more victims and the bobcats’ overall survival rate fell to 39%. All tested positive for concentrations of anticoagulant rodenticides; some had been acutely poisoned, said Meghan Keating, a doctoral candidate at South Carolina’s Clemson University. That was a troubling sign for a population that now numbers less than 20 individuals. They are regularly exposed to rodenticides, as rodents (including rats) are a major part of their diet, Keating said. Also troubling is that her team found exposure to not just one, but a cocktail of rodenticides. “We haven’t had a bobcat test positive for less than two rodenticides,” she told Mongabay. Kiawah Island’s rodenticide-driven bobcat decline may be an outlier, given its…This article was originally published on Mongabay
