I stand corrected. In my defense the numbers do vary.
http://en.wikipedia.org/wiki/Cougar
Never knew they had so many names.
I still say they are not a creature of habit. They still cover alot of area.
I will stand by my view that people that see them all the time in the same spot are a little imaginative. Don't want to say they are full of it bit but I am skeptic.
Info from the link you posted:
Social structure and home range
Like almost all cats, the cougar is a solitary animal. Only mothers and kittens live in groups, with adults meeting only to mate. It is secretive and crepuscular, being most active around dawn and dusk.
Estimates of territory sizes vary greatly. Canadian Geographic reports large male territories of 150 to 1000 square kilometers (58 to 386 sq mi) with female ranges half the size.
