I live in California and maybe our opposums are small compared to the monsters with poison teeth you southerners are describing, but I've volunteered for wildlife rescue and we rehabilitate ALL injured and abandoned animals no matter what and what I do know about opposums is that like any wild animal, they will bite if cornered, but also "play possum" by literally passing out when threatened, they are scavengers preferring carion, eggs, chicken feed, cat food, garbage leftovers, lizards, insects (love snails, so great in the garden), but will hunt when necessary like any scavenger. People are so harsh on the scavengers, but if we didn't have them, we'd be knee deep in road kill!! I've NEVER seen a rabies case come into the rehab center, (usually bats and skunks), and while it's not likely, it's not impossible.
I know I'm just a granola-eatin' Californian (although my husband is a hunter), but all wildlife is necessary to this planet and deserve to do what they do in the food chain. I'd capture and relocate.
Wanna know what else I know about opposums? No joke, the boys have two.....well, let's keep this family oriented, shall we?
Not a joke. I was just as shocked.
