Once Bo came ripping through the cat door meowing like crazy. He came running over to me with a piece of plastic bag in his mouth. It was so strange. Well he did it again. Ok well I was out in our yard and noticed a piece of the same plastic bag near our ivy wall. Well it turned out there was a nest of rat's in there!. It was like he was telling me. Turned out my other cat took care of the infestation (yuck). But how funny!
