According to A-Z Animals, birds of prey, such as owls, hawks and eagles, consume weasels. Foxes, snakes and coyotes eat weasels as well. Even though weasels are fast, these predators have learned how to hunt for weasels.
The Adirondack Ecological Center explains that the most common avian predators of the weasel are the great-horned owl and the northern goshawk. There are no animals that prey primarily on weasels because of their agility, speed and scent glands. The scent glands located near the weasel's anus release a horrid, nauseating scent that deters most predators.
In some areas, weasels are hunted by domestic dogs and cats if the weasels are near heavily populated areas. A-Z Animals says that weasels are considered pests by farmers because the weasels steal eggs, kill livestock and create chaos on the farm.
According to the Encyclopedia Britannica, weasels are carnivorous, aggressive predators. They are solitary animals with slender bodies and flat heads. Weasels kill multiple prey at once because they cannot store fat. Weasels kill the animals and then store them in burrows to eat later. Most weasels consume up to 30 percent of their body weight each day. A weasel's diet consists of mice, voles, birds, eggs, rabbits and other rodents.
