The Undercover Cat Teaser.

This is the cat toy that entertains and exercises felines by encouraging them to stalk an elusive "mouse" scurrying beneath a fabric skirt (Play Video). The unit silently spins a wand under the ripstop nylon canopy, changing its direction unpredictably to imitate the movements of a real rodent. The mouse's tail peeks out tantalizingly, making it irresistible to even skeptical toms or tabbys. The unit's gearless friction drive prevents damage once the prey is caught and its speed adjusts to one of four settings with a push of a button. The toy's low center of gravity and fold-out stabilizers prevent it from tipping during exuberant feline pursuit. Requires three AA batteries. 4 3/4" H x 23" diam. (1 lb.)
