Furry tagging

Are furry characters expected to wear the same clothes as humans do? There are quite a few images for unclothed characters with and without the nude tag. Although many without are pokemon personifications.

post #1639908 and few other images have the tag for the animal added (here cat_ears, cat_tail, cat_nose AND cat)
At what point should the tag for animal itself be used?

As long as they have a mostly humanoid shape, I'd say the nude tag can apply, yes.

For the cat tag, I thought that was just for actual stands-on-all-fours-type cats, not anthropomorphic people?
