We've had possums in the neighborhood for several years now, but just tonight there was one on my deck. I have a 3 pound dog who is not allowed off the deck due to the possum problem, now I don't feel comfortable letting her out, even when I'm there. (I never leave her alone after dark.) I don't know what to do now. I live in town, so releasing the possum on the property is not an option. I'd like them gone. Period.
