check your trees,,, we used to,,,, I say again,, USED TO,, have possums in the trees, they would run across the fence and go to the neighbors house to eat the cat food. One night, the dogs were going nuts,,,  I caught the little B@st@rd, with my spot light,, he froze, on the fence. I whacked him with a stick, he fell off,  and he ran off. A week ago the dogs caught a small possum,, he became a chew toy. We don't have much problems with possums anymore, they stay away.
@KTownTexican:
Mine are possum killers too. They've killed 2 and let 1 get away. We haven't had a problem in over a year. The dog that was barking last night stands at their back door and barks. Never runs around doing. Just sits at the door. Poor thing. He finally stopped around 2am. 4951
