From what I've researched, there are anywhere from 1-15 species and subspecies of cougar in the Americas. The taxonomists cannot agree, partially because they are in such low numbers with massive overlapping ranges. Those found in Arizona, Peru, Patagonia, Alaska, Alberta, Everglades, Quebec/NB, vary in size, and primary prey (related, no?) as well as coat thickness (climate and size related, no?). Historically they were named by the locals: Cougar, mountain lion, catamount, panther, puma...
Those found in NB have been shown to have DNA related to other strains, but no one is sure that those native to the Acadian forest ever were distinct genetically. They may be purebred escapes, mutts with captive foreign and local native, or purely native.
Bottom line: they exist, there here, they're incredibly stealthy, very rare, small population, massive range, and hard to mistake for another cat, if you see the whole body (and are educated on our cats).
Believe it or not the cheetah's closest relative is the cougar. Apparently after the ancestor came across the Bering Land Bridge and populated all of NA and SA it went back, eventually evolving into the cheetah back in Africa.
