I know cougars,or american lions ( there are several names for this animal; paint,catamount, mountain lion) are in british countryside, likely released exotic pets. Cougars wiegh @ 110-180 lbs with the females @ 30 % smaller. They live in the wild @ 10 years, are solitairy except for mating and hunt from dusk to dawn ( daylight activity is not unusual.) They feed on many animals and will cache a kill with dirt and debri. Tracks consist of 4 toes and a trilobed pad, claws retracted with the front larger than the rear. Usually a walking cat will place hind paws in the front's imprint. If observed distinct he/she is loping or running. Cats will stalk and atttack from behind. They kill with a massive bite to the base of the head or neck. If you think there is a cat nearby make noise. If you see a cat NEVER turn your back or run. This triggers the attack response. Make yourself look big, raise your arms, hold up a rucksack etc. and remain quiet as you slowly retreat. If it does attack DO NOT play dead. Now you yell,kick,punch and fight back. California has several thousand cougars and we have had a few rare fatalities and attacks. Most of these animals were underwieght, old or young. We banned hunting and now the combination of unchecked urban development and their rising number is pushing many animals out of a decent home territory. The isolated animals over there seem to be doing well enough on wild game and domestic stock and have little chance of mating. Still , on the odd chance you stumble on tracks or a kill cache keep your head. Finally,should you see one without incident appreciate their beauty. Just don't tell the ley Line and crop circle set.
