My 16 year old cats loves this
My cat purrs away while chasing the ball, she loves it. This does, however need a helping hand from myself to keep the ball moving. Once she is interested it does go from one end to the other by itself thanks to the slopped ends and her batting it.The quality seems good to me, no issues there. Only given 4 stars as does need some human interaction once stopped. Perhaps a weighted/ ball bearing filled ball would keep going longer?
