There is a plastic chip in the ball, which must be removed before using the ball. Catit Design Senses Super Roller Circuit, including four elevated tracks, four regular tracks and one illuminated ball, takes fun and action to a breathtaking new highs and lows. This very large 8-piece play circuit is the ultimate exercise stimulator. Trouble shooting steps: The ball does not light up. If the plastic insert to activate the ball been removed, the batteries may have become unaligned, to realign them hold the ball so that the Catit symbol is directly on the bottom and give a sharp tap on a hard surface. The item keeps coming apart and the ball gets stuck within the tube. The circuit has not been correctly put together, if the circuit is correctly locked together it is difficult to separate the top and bottom parts without unclipping them from the underside and impossible for a cat to do it. Ball getting stuck this is either caused by the circuit not being correctly setup or not being used on a flat surface or used on a carpet with a deep pile, this allows the sections to not sit flush and so reduces the area the ball can pass through. Note: There is a plastic chip in the ball, which must be removed before using the ball.
