Reports of Pumas in Britain:

The best explanation are they are product of private collections that escaped over the last 200 or so years and enough escaped to form a breeding population. A second problem is unlike the other branch of the cat family (i.e. the lion, tigers and Leopards) Pumas LEARN to hunt from their mothers (Lion, Tigers, and Leopards are instinctive hunters). Thus how did these Pumas survive in Britain where the main prey of Pumas in North America is the White Tail Deer, which is a lot smaller and nimbler then the Red Deer of Europe (Red Deer of Europe is closely related to the Elk in North America, the Elk of Europe is closely related to the Moose of Europe not the elk of North America, yes the same names for different animals depending on location). Furthermore how could a small breeding population adapt to hunting in Britain, given that the parents were themselves domesticated cats (i.e. did NOT learn to hunt from their mothers)?
Can Pumas learn to hunt Red Deer? Yes, Pumas and their close relatives can learn to hunt new game (Cheetah may be a close relative and also "learns" to hunt, the relationship between the Cougar and the Cheetah is an item of hot debate among researchers at the present time). Pumas, unlike Cheetahs are a night animal and thus tend not to be seen. Last year (2007) brought a report of a Puma in Western Pennsylvania. Generally these are dismissed, but it was reported by a Game officer who is familiar with the Animal. Officially, Pumas only exist in the Everglades in the Eastern US, but we have had reports up and down the Appalachian Mountains for decades. Most reports are dismissed as mistakes i.e saw a Bobcat can called in a Puma, but many such reports mention the long tail, the Bobcat has a snub for a tail, the Puma a long tail.
A further problem in an area where Pumas are NOT hunted, pumas generally take up personnel hunting area of about 10-300 square miles (Depending on game available, the less game the greater the territory, males hold a wider area then females with females and male areas overlapping). A Typical American County is only 20 square miles, Thus an American County may only hold four Females and one male Cougars if there is plenty of game. Looking it at a different angle, that is only five cats per county, such a low population would be hard to find (Hunting Cougars actually increases the cougar population in an area, the cats are less able to fight off other cats do to hunting pressure so more cougars can live in the same area). In the east, Cougars are NOT hunted (They are hunted in some Western States). Thus you have Cougars claiming the largest territory they can hold. This reduce the number of cougars per sq mile. Furthermore Cougars are NOT fast breeders. Unlike house cars they only have one litter per year and then only one to two kittens. A female may only breed for ten years. Thus, the maximum number of new Cats a female Cougar can produce over her lifetime is 20 (And most cars will have ten or less kittens over their life time). These 10 kittens must not only replace their parents but any non-breeding cats (and cats that die BEFORE breeding).
Given the widespread elimination of Cougars in the Eastern US, it would take decades if not centuries for the cougar to recover (unlike Domestic Cats which breed like rabbits). The same thing for any Cougar "invasion" of Britain, it would take decades if not Centuries for the Cougar to spread, thus the low report may reflect a low population, NOT that cougars do not exist. The "Great American Ghost" did not get that nick name for being seen, the cougar has had to live with people for over 10,000 years (Ever since the First Native Americans entered North America) and has survived when other cars, including American relatives to the Lion, have all gone extinct (The Jaguar is of the lion branch of the Cat Family, but rarely seen north of Mexico).
