While cougars are apex predators and have few natural predators, they can be killed by several other animals, particularly when they are young or weakened by injury or illness. Here are some examples of animals that can kill a cougar:
Wolves: In areas where cougars and wolves coexist, wolves can kill cougars, particularly young or weakened ones.
Grizzly bears: Grizzly bears are powerful predators that can kill cougars, particularly when they are competing for the same prey.
