Louis William Wain was an English artist best known for his drawings of anthropomorphised cats and kittens.
More cats!
For some reason, it’s always bothered me in stuff like this, that if one of the animals wears clothing, it implies that “in universe” animals wear clothing, which means any animal not wearing clothing is walking around in the nude.
Basically the same issue as “the implication of Winnie The Pooh wearing only a shirt is that he’s walking around swinging his knob about”.
The way I understand it is that, since most of the time it’s animals with fur or feathers, they’re not really exposing themselves in the same way as humans would in the same situation. Thus, in universe, clothes are a styling choice.
Except for Donald Duck covering his lower body when losing his shirt. That one doesn’t make sense in any case.
