>> There’s nothing “dangerous” about a possum. They’re the only animal nearly immune to rabies <<
My county health department told me exactly the same thing when my dogs caught and killed one in the backyard. I volunteered to bring it in for testing, but they said not to bother. Just put it in a plastic bag for the next trash pick up.
(But they said that if the poor creature had been a coon or fox, my dogs would need to be quaranteened.)
