HA HA HA, I'm really enjoying reading this Thread !
I can't believe you guys are afraid of a Possum, and,
AlicetheYorkie and I agree totally.
We have a Resident Possum, who comes through the Yard
at night, after I close the Doggy Door. HA, I think he wears
a watch or something, cause after he came too early once,
and both of mine let him know he was trespassing, he's never
made that mistake ever again.
As has been said, they are very docile creatures, unless you corner
them. Are EXTREMELY valuable to us as Nature's Little Janitors,
and will totally clean your yard of dead things and any garbage or
table scraps you would wish to leave out for it.
Please don't harm it, or cause it to run off very far.
