Now this really surprises me, I thought you guys had a better concept of animal husbandry than this !
That poor little Possum wasn't hurting anything, just trying to eak out a modest subsistence.
Of course, I hope you realize I'm razzing you a little here, but...
We have a Possum named "Sweetie", which comes through the yard each evening. Those little guys are just great Janitors for our environment. Anything left in the yard (dead/whatever) is gone by morning.
TxVicki, I rather doubt that your intervention with it, will have much effect on it's return. Those guys are creatures of habit, and the only way to "reduce" their tours through your property, is to eliminate any food/water resource which may attract them.
I go with the flow...
We have a Doggy Door, and close it each evening at 8 PM. Both of my Yorkies are regular attendants at the (closed) Patio Door, and growl viscously, when they see Sweetie pass through.
Sweetie and the Postman, are two of their highlights of the day.
