The term 'Western Predator' refers to two large cats found in the western hemisphere, the PUMA (also known as the COUGAR or Mountain Lion) and the COUGAR. The PUMA 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 COUGAR is a large cat native to North and South America, ranging from Canada to the southern tip of South America. It is the fourth-largest cat in the Americas after the Jaguar, PUMA, and Ocelot. Both the PUMA and the COUGAR are apex predators, meaning they are at the top of the food chain and have no natural predators.
