My first remark is that it 's hard to find or see cougars, like a ghost you can 't find or see them. Next thing is that there very nimble, fast, and slim plus they look elegant when they move, like a ghost very fast and in away elegant. Third is that they attack or hiss at enemy 's (other animals), like if you mess with a ghost they might attack you. That 's why I think cougars are called "Ghost Walkers" as said by Patricia Corrigan in the Cougar
