Toots Rileyopossums naturally have big round ears, but you often see them with crumpled ears or no external ears at all because they are very prone to frostbite.

I actually saw an opossum for the first time in my alley like last week.
It. Was. GLORIOUS 
@thesyc66 one night when my cat was missing for 15 days (he's home it's fine), I went out looking for him after midnight, because I read that they're less skittish and more likely to come to you then.
I was a couple blocks away and I saw an injured cat dragging itself down the road. Oh no, I thought, it's Leo and he got hit by a car.
I was like ten feet away when it turned around and revealed that it was in fact an uninjured possum. We were both terrified and ran in opposite directions, lmao.
