When I'c come home from the grocers, Lishan and Sefu would wait for the paper bag to drop. They would race to see who would get in first, sometime it was a tie. I'd scratch the bottom of the bag and OH the punches from the inside to get whatever was scratching the outside. Cats are playful creatures, all their lives.
cats & bags are a natural for a laugh.
did you see the video (the link I posted earlier in thread?).. funny to see thier antics. I have quite a few kitties here.. they are always putting on a show!
