Pep up your cat’s winter with this automatic mouse-chasing cat toy
This toy is popular with cats because it incorporates two traditionally satisfying features: something to chase, and an obstacle to chase it around. The base of the unit is a long plank which is held up from the floor by a couple of inches. The loop of rope which spans the board’s length has a mouse attached to it with about six inches of string. When the motor (from a Roomba) is flipped on it bounces and jerks its way around the circuit, darting in and out of the space below the base.
