Felines are a group of carnivorous mammals that includes CATS, pumas, and other species. CATS, which have four letters in their name, are the most common type of feline and are found in many households as pets. Pumas, which have five letters in their name, are larger and more powerful than CATS and are found in the wild. Both CATS and pumas are members of the Felidae family and share many characteristics, such as sharp claws and retractable claws.
