Often known as the Mountain Lion or Cougar, the Puma can be anything from 4 - 9 ft (1.2 - 2.7m) in length of which a third is made up of the tail. The female is generally smaller than the male and can weigh as little as 46lb (21kg). The head is much rounder than usual in cats and their ears are also more rounded.  The colour of the short fur varies from a yellowish-brown to red, and is sometimes darker in the winter.  The throat, chest and belly are white with the ridge of the back and the tail usually marked by darker line, the tail being tipped with black.  The Puma leads a solitary life and usually hunts in an area of 12 square miles, favourite food being deer. Pumas are sometimes reported as   having been spotted in the UK, usually when it is a nice hot sunny day they are spotted sunning themselves on a rock or patch of grass near to a wood.
