Problem with the ball getting stuck
BACKGROUND: We've recently adopted a very playful 2 year old cat. We knew from her fosterer and watching her that she loved the circuit the fosterer had so decided to buy one.
PROBLEMS: She wouldn't play with it as the balls kept getting stuck in the 2 end pieces which was extremely disappointing. It seems to be a design flaw/manufacturing error but either way she was not impressed.
SOLUTION: We removed the end pieces and made a round circuit instead. She is back to loving it again.
