Cougar

A cougar looms nearby Heartland and has been reported to have killed one of Stumpy's colts. The next day, Amy finds feathers by the coop and they believe the cougar has killed Charlotte. When Lou later goes on a trail ride with Peter and Richard the cougar leaps out growling at the trio, causing Richard to fall from his horse until they're able to scare it off. The next day when Amy and Ty are out for a ride the cougar once again jumps out ready to attack Amy until they hear a gunshot. The wildlife warden tells them that it's only a tranquilliser and they'll take it to a wildlife reserve a few miles away. After Jack finds her kitten, Scott takes it out to join the cougar to keep them together. (Growing Pains)
