That depends on what your requirements are. But if it were me, I'd do my favorite animal or an animal that represents something about me or something I care about. Hope this helps! =^-^=
i think that you should do a rabbit, because bunnies are so fluffy and cute, plus when i was little,(i'm in cps) my mom was visiting me and she gave me a big stuffed rabbit. Me and her love bunnies she has like 3 rn, she talks to them cause she has phschitzophrania, but yeah i love bunnies.
