In a lot of ways cats are the black hole of art, because most of their obvious qualities – grace, softness, poise – are present to such an extent that making art about it only makes it worse. It’s no coincidence that basically all the cats in popular culture ignore most of the attributes that make cats cats. They’re all graceless boors: Sylvester, Tom, Garfield, Bill, whoever. (Hobbes is about as debonair as they get, and he’s got some significant lumpy qualities, plus a few meta dimensions – and I’m not counting personalityectomies like the Pink Panther.) It’s an attempt to find something in these animals that we as humans can really relate to.
Oh and by the way I am a cat person. Dogs have different issues when it comes to drawing them, but they’re easier on the face of it, because most of their obvious qualities aren’t quite so unilaterally flattering.
