Cougar

Cougar is the main antagonist of ''Homeward Bound: The Incredible Journey. ''He was a mountain lion that Shadow and Chance encountered while they were trying to find food. When they thought they were done for, Chance revealed that the TV remote was under the seesaw. Shadow came up with the idea to lure him to a rock seesaw, and Chance catapults him off the ledge. Their barking also led them to reuniting with Sassy.
