Cranky cats
Cougars are top predators in Yellowstone, preying on many of the same animals as wolves. Cougars are solitary and hunt by stealth and ambush. They prefer rocky areas where they can hide. A cougar is more than a match for a single wolf. However, bears and packs of wolves can displace cougars from their kills as cougars prefer to avoid fights. In general, wolves and cougars steer clear of each other but they will kill each other’s young, given the chance.
