On the other hand, the cougar itself has to fear the big timber wolves when maddened by the winter hunger and gathered in small parties; while a large grisly would of course be an overmatch for it twice over, though its superior agility puts it beyond the grisly's power to harm it, unless by some unlucky chance taken in a cave.

Nor could a cougar overcome a bull moose, or a bull elk either, if the latter's horns were grown, save by taking it unawares.

By choice, with such big game, its victims are the cows and young.

The prong-horn rarely comes within reach of its spring; but it is the dreaded enemy of bighorn, white goat, and every kind of deer, while it also preys on all the smaller beasts, such as foxes, coons, rabbits, beavers, and even gophers, rats, and mice.

It sometimes makes a thorny meal of the porcupine, and if sufficiently hungry attacks and eats its smaller cousin the lynx.
