The Catstages Twist-A-Ball Track Convertible Cat Track is a playtime innovation designed for the ball track loving cats who crave versatility and a continuous challenge. This three-in-one convertible cat ball track offers three distinct ways to play. Use it as a standing cat ball track with the base on for bat n' swat fun. Remove the base, and you have a rolling ball track for dynamic play that keeps your cat active, engaged, and entertained. Convert it into an infinity track by simply twisting your hands in opposite directions until the ball clicks, providing a mesmerizing and never-ending play experience.

They gracefully stay within the track despite the batting and swatting your cat may perform, ensuring endless interactive play.
