Berlioz is a major character in Disney's 1970 animated feature film, The Aristocats. He is a gray-furred kitten, the youngest son of Duchess, and the younger brother of Toulouse and Marie.
Obviously, don't nominate any human characters. Hybrids like Cheetah or The Lizard are okay, as are shapeshifters with one set animal form (eg Professor McGonagall.)
