The Magic Cat Track and ball toy consists of 82 pieces of flexible tracks and 2 balls. The balls are placed on the track which will roll wherever your cat pleases by pawing it. The balls are snapped in and they usually will not pop out of the track but if they do, they can be easily snapped back in. A little catnip can help introduce your cat to the track for the first time. The track can be laid out in several different shapes and configurations as shown on the images. Additional tracks can be endlessly combined to create larger and more customizable configurations. Each track is suggested for up to 2 cats, and can be multiplied for bigger cat families. Please Note: When taking the tracks apart, please do not pull them from one side because this may cause damage to the connections. The two track pieces must be placed on a flat surface like a table and pulled apart from both sides until they are detached. It takes a little extra force. It is the same when you snap the pieces to connect. The pieces must be on a flat surface.
