Thank you everyone. By now, his ear just has some dried blood in it. No more swelling and he is eating and acting normal. This is one of the dooooooooooooown sides to letting a cat outside and I will never have another outdoor/indoor cat (Moon stays indoors only) but I can't break Bean of it now. When I grew up, we let our cats outside. I have lost many. Yet still I never thought about not letting them out as I got older and had my own. Now I do and any further cats will be indoors only.
