Mountain lions climb trees. These big cats spend most of their time on the ground but have been known to easily scale a tree, especially when trying to escape a threat.
Mountain lions are solitary animals, and their most prominent threat, other than wolves, are humans. When hunting or tracking mountain lions, humans often use hunting dogs that chase the lions up trees. Mountain lions have incredible strength and can leap up to 18 to 20 feet into a tree. They once populated the entire North American continent, but because of human expansion and hunting, they are mostly only found in the western part of the continent.
