To start things off, I’ll say Monsters Inc.
I guess because many of the creatures are…well…monsters which don’t particularly resemble any individual animal it has had less of a substantial furry appeal. However, on closer inspection lots of them are clearly based on at least one real or imaginary animal, with many being a combination. And for me, the main villain Randall seals the deal. He’s pretty much EXACTLY a large chameleon, and he’s awesome! I mean, he really should be an icon for scalies!
