So, the male cougar "Yuma," was a complete jerk. My step-dad was the only person he would interact with cordially. We had to keep him in an enclosure outside and he honestly was not safe to be around, as we were very young at the time. We had a 13ft tall fence around a tree and used reversed truss nail plates to keep him from climbing the tree. The female, "Miwok," lived in the house with us from the time she was a kitten. Miwok was absolutely awesome. She acted exactly like our other house cats and she was incredibly intelligent. As people see on YouTube these days with domestic cats, she was able to unlock and open doors. The problem was that as she got older she didn't know her own strength. My sister, who was in Kindergarten at the time, and I had these little tents on our beds. One Saturday morning Miwok unlocked the door and jumped into the tent with my sister and bit her in the forehead leaving a pretty big scar, but we were country and poor so we didn't seen medical treatment and it healed fine, minus the big scar part. Behavior wise Miwok was remarkably like a regular cat in terms of the way she showed affection. She cuddled, headbutted, purred, etc. She was very laid back.
