Ball and track for cats with pivoting base

摘要

An animal amusement and scratching device causes a ball to be self-moving. The ball (16) is confined within a circular track of housing (10) and is viewable from the top opening (14) of the track by an animal. The slightly curved bottom edges (18) and (20) of the housing base causes the housing to be unstable. When a cat steps on any part of the device's upper surface to claw scratch on the carpeting (12), it will prompt the ball to roll by itself within the track when the unstable housing (10) rocks or teeters under a cat's weight. The unexpected movement of the ball attracts an animal into imminent play.
