Heroes in animated movies come in all shapes and sizes and sometimes even all types of species. So why not in the form of a cat? Not all cat heroes have the same story, but they do all captivate viewers with their feline ways and irresistible eyes. One of the most loved cats in animation is Puss, who was originally introduced to fans in the popular comedy franchise, Shrek.
