I didn't bother returning it, as it didn't cost much, and was too much trouble to have my mother mail it back out to return. I bought it as part of a group of gifts for my mother's cats for her birthday. She was disappointed to find that it was cheap and junky (her words, I didn't get to see it).

Our two cats, a Tabby and a Calico, showed very little interest in this, although it performed as advertised.The tabby is the personification of Garfield so I was not surprised that he was bored, but I thought the Calico might chase it. No luck.
But they loved the box it came in!
