Due to the fact that bobcats are still hunted for their pelts in 38 states as well as Canada and Mexico, human beings are their main predator. Aside from humans, adult bobcats are threatened by mountina lions and wolves while bobcat kittens fall prey to large owls, coyotes and foxes. Diseases such as rabies, and other conditions caused by parasites are also cause for bobcat deaths.
