A few days ago, I was just looking outside, when I saw a possom head towards our coop. I went up there to check on the birds when the door slammed by its self. Luckily, all the birds were alright. That night, we saw a possom on our porch eating some cat food (we have a lot of strays). So, we set a trap. A few days later 1/3/11, we saw the trap shut and a furry thing in the trap. It was a possom. So, we set it free in a park a few miles away from the house. So, no more possom, or pest problems, problem.......yet.
