The term Western Wildcat is used to refer to two large cats, the COUGAR (also known as the PUMA or mountain lion) and the PUMA. The COUGAR is a large cat native to the Americas, ranging from Canada to the southern tip of South America. It is the second-largest cat in the Americas, after the jaguar. The PUMA is a large cat native to the Americas, ranging from Canada to the southern tip of South America. It is the fourth-largest cat in the Americas, after the jaguar, COUGAR, and ocelot. Both the COUGAR and the PUMA are apex predators, meaning they are at the top of the food chain and have no natural predators.
