The cougar (Puma concolor), also commonly known as the mountain lion, puma, panther, or catamount, is a large felid of the subfamily Felinae native to the Americas. It is found from the Canadian Yukon to the southern Andes of South America.

The bobcat or bay lynx (Lynx rufus) is a North American cat that ranges from southern Canada to central Mexico, including most of the contiguous United States. The bobcat is an adaptable predator that inhabits wooded areas, as well as semidesert, urban edge, forest edge, and swampland environments.
