You would be wasting your time trying to "call" a cougar, it just won't happen. In any event, they will be hunting you as you walk to your treestand. You must hunt them with dogs or be one of those guys truely in the right place at the right time and just happen to see one and take him down. I live in Oregon and i know your pain, cougars are decimating the deer and elk population and the liberals at the capital know nothing about management. I will shoot one even without a tag if i saw one ( i do have a tag though, lol) and the Oregon Department of Fish and Wildlife even condones it to an extent because the bureaucrats have strong armed them on cougar regulations.
