I know someone posted a vid about this toy a while back. Called Cats Meow, it is a mat with a 'mouse' spinning back and forth and around and about.
Just saw an ad on TV this evening, it is on special, buy 1 get 1 free, cost is $10 plus s&h, at this web site:
Runs on battery. Quite a bit more costly on Amazon.com!
I remember the vid, the cat(s) were enjoying the toy. Was it Gabriels Girls? I tried a search but I couldn't find it.
