Without a doubt, two favorite feline games are stalking various household items and rolling around in brown paper grocery bags. There's an innovative new toy on the market that combines both of these stimulating pastimes. Thing in a Bag, which looks like a regular brown paper bag but is actually made from a tear-resistant material, has a randomly activated motor that makes it look as though an invisible "creature" is moving around inside the bag. The on and off motion of the "creature" is designed to further heighten kitty's natural stalking instinct. Materials inside the bag provide the authentic crinkling sound that is sure to drive all playful pussycats into a frenzy. Runs on AA batteries.
