recently we have had a lot of opposums here , Ontario ! , at the front door , at the garage -- they are harmless, beneficial , awesome biology , high immune system to most bacteria and even rabies -- something worthy of study.
They play dead , and will emit "dead" smelling scents , which inhibit prey on the dogs. Yes one of my dogs found one in the garage and picked it up , ran the victory loop then brought it to me . I held her collar , she released, I flipped her outside of the garage door while I was inches away absolutely fascinated by this primitive living creature . Put in on the grain shovel , and marched it to the tree line . Watched it wander off .
They don't dig, or destroy wiring -- will catch and eat roof rats --
