Don't jump out of your skin when you see the mountain lion. First off, you most likely will never see one, and if you do it will be off in the distance. Mountain Lions are primarily solitary animals and a single male lion may require up to 175 square miles of territory for its home range.
Mountain Lions generally are found in remote mountains, canyonlands, or hilly areas with good cover. The Mountain Lion is a large, slender cat with a smallish head and noticeably long tail. Its fur is a light, tawny brown color which can appear gray or almost black, depending on light conditions. Mountain Lions are also called cougars and pumas.
Mountain Lions are relatively uncommon, secretive animals. They are carnivores that prey on a variety of animals; some favorites include deer and wild hogs. Other prey animals included in the Mountain Lion's diet are rabbits, jackrabbits, javelinas, and rodents. Some lions occasionally kill livestock or dogs.
These are mostly nocturnal animals, they hunt usually at dawn, dusk and at night, and have limited activity during the day. A Mountain Lion is a good hunter. It can follow its prey for hours and it can wait somewhere in the ambush at the distance of 15 meters while it prepares for a suitable moment. Then it uses its powerful legs to lunge at its prey with single running jumps that can reach over 12m. It then leaps onto the back of its prey and breaks the animal's neck with a powerful bite.
Seldom does a mountain lion attach a human. If it does, fight back. Children and pets should be watched carefully to make sure they are not getting into a situation where the mountain lion might be waiting.
