With the exception of the Penguins and Polar Bears (which have their own page since there are so many of them), these are the icons that feature some sort of animal. I might have missed a few (I'm sure there are some still on the Misc. Icons page) but I figured it was a big enough sub-section to warrant its own page. Some are contest rejects, others were made for other people, and some are just because. And a few are probably even ones I made for icontests, but my stuff was copied all over the place and sorting them all was a nightmare, so... yeah, you might see some repeats. And I'm sure there are still tons of animal icons scattered about, off the top of my head I know there are plenty in Animal Icontest, Animal Stillness, Basic Icontest, Dog Icons, Dog Icontest, and Themed Icons.
At the bottom there's also a great number of animal bases, some made from random cute pictures I found while browsing the picture feed, others I made for the bases for various Basic Icontest rounds.Animal Icons:
