My husband saw a adult cougar on Indian Mt Rd (Lakeville/Sharon Border) and again a cub playing in a neighbors driveway about 6 years ago. He knows what they look like as I am an artist and have painted them. From what I understand The NY fish and Wildlife released a cougar pair near the Bish Bash Falls area many years ago now, at least 40 years or so. They were released to see if they could bring down the deer population. I believe what we are seeing now are the descendants.
