The study's authors examined the stomach contents of 91 fishers, whose carcasses they had found in Pennsylvania. Of these fishers, 12 had bits of other fishers in their digestive tracts. ![]() The team speculated that the Pennsylvania population of fishers had grown so large so quickly that the animals were competing with each other for food and had grown aggressive toward one another.

Fishers "run circles around to try to exhaust them," Joyce said. As the porcupine tires out, the fisher will snap at the quilled animal's face. Enough bites to the face, and the porcupine will eventually bleed out and die. Once the prey has died, the fisher will grasp the porcupine's face in its jaws and twist the prickly creature upside down to expose the belly, so the fisher can safely eat without getting quilled. However, fishers are sloppy eaters and will occasionally swallow a quill or two, Joyce said. But the quills don't seem to bother the fishers much.įishers also don't seem to care if they get a quill to the face. While fishers don't have superpowers making them immune from quilling, they seem to be able to fend off infections from quill injuries that would kill other animals, Montana Public Radio reported. In an unpublished study of 100 fisher skulls collected by hunters, Joyce found that about one in 10 skulls had quills embedded in them, suggesting the tough little creatures had survived at least one unfortunate quilling.įisher cats were once heavily hunted for their warm fur coats. Although they may look fuzzy and cuddly, these small mammals are fearless hunters. In addition to fearlessly hunting porcupines, fishers can also take down lynx - predatory cats that are about twice the size of an average fisher. Researchers tracking lynx with radio collars occasionally found their subjects dead in a snowdrift, with little fisher-size bite marks along their necks and heads, National Geographic reported. "A fisher really doesn't have any boundaries in the size of the animal it's willing to attack," Scott McLellan, a wildlife biologist with the Maine Department of Inland Fisheries and Wildlife, told National Geographic. The fisher cat's reputation as an aggressive hunter has led to unfair and unfounded rumors that fisher cats attack and eat pets and even small children. ![]() ![]() "I'm not aware of any, and I don't think there are any cases of fishers attacking humans," Joyce said, adding that while a fisher cat probably wouldn't think twice about eating a house cat if the opportunity presented itself, studies of fisher diets in human-dominated landscapes suggest your cat is probably safe. (Cats have more to fear from coyotes, owls and cars.) The rumors are likely fueled by the fact that the fisher's range is expanding, so people who have never seen the elusive animals before are now seeing fishers in their yards ( and in some cases, trash cans). About that screamĪnother unusual characteristic of fisher cats is their piercing screams. Internet forums say a fisher's blood curdling screams, let out in the dead of night, signal that the creature is about to attack. But those noises are probably misidentified foxes, Roland Kays, curator of mammals at the New York State Museum, wrote in the New York Times. Foxes are generally very vocal, and therefore easy to record, while fishers are typically silent in order to better hunt their prey.
