Mountain lions hardly ever harm humans, although they will attack in self-defense or to protect their cubs. Because they are territorial, they will defend their established ranges, particularly at courtship time. When they do attack, they kill, which has given them a reputation for savagery. They are an important predator at the top of the food chain, focusing on deer and elk and thereby helping to keep these populations healthy and habitat from being overgrazed. But the more specialized a species, the less adaptable it is to change, and the cougar has proven relatively unable to adapt to habitat loss and competition with humans for large ungulate prey.
Mountain lions are now a protected species throughout the United States.
The mountain lion is secretive, and the sight of one is rare. Only by accident will you spot a mountain lion unless you are with an expert guide. If you have the good fortune to see one, it will likely flee the minute it sees or smells you. Do not attempt to approach a mountain lion. 2.Never leave pet food outside.
