The puma, also known as a mountain lion or cougar, lives in mountainous regions of North America and some areas of Canada. They prefer temperatures between 59-66 degrees Fahrenheit and humid, warm climates. Pumas are solitary animals except for mothers and kittens. They are mostly nocturnal and sleep for 4-5 hours per day, hunting small animals, deer, and other pumas. Their populations are threatened by loss of habitat and hunting, with only around 30,000 pumas remaining worldwide.
