Puma
Pumas are mainly tan-color, and can be up to 9 feet long, although average length is 6 – 8 feet. They can weigh from 29 kilograms to 90 kilograms.  (The males are larger.)  Most pumas live up to 21 years. Although pumas are very large and some are larger than humans, the puma is classified as a small cat. That means that, in scientific terms, the puma is more closely related to the domestic cat than they are to lions. Unlike the big cats in the genus Panthera, the puma cannot roar. Instead, it can growl, hiss, screech, and purr. Since pumas are, in the biological sense, small cats, they are capable of purring continuously. The big cats can only purr while breathing out.
