"I was so excited for my cat to get this toy. It was cute and promised a lot of entertainment. At first, my cat didn't know what to think of it. So I batted the ball around for her to understand, and she took to it right away. She continued playing throughout the rest of the day, batting for the balls (but ignoring the mouse). I thought we had a hit.
Since the first couple days, however, it's been collecting dust. It's almost like she's given up and is turning her nose to the unrewarding challenge. We tried hiding her mouse toys in the middle part (which is pretty darn cool), and she easily fetched them out and continued ignoring it.
I'm not sure if anyone else has had this experience, but perhaps this toy is meant more for kittens than adult cats. I took a shot, though, and I still recommend it as it's a well-made, clever product."
