I know someone had mentioned these at some point on the site... well I was in walmart tonite and on my usual stroll through the pet section, I decided to try one for Oliver since it was only like 5 bucks... I wasnt sure how he'd react as he can be picky about toys, but he LOOOOVVEEESSS it! haha... it works best on the hard floor in the kitchen - I had to show him a few times where to hit it and then he got the hang of it and will come running if I'm in the kitchen and hit it and he's in the other room... I like that it has a master on/off switch too - it will DEFINITELY be turned off at nite (Oliver likes to have 5am playtime, haha)... just thought I'd share - he's the kind of cat that comes running when the DVD player is opened (I even kept my old DVD player after it stopped reading discs properly simply to be a play toy for him, haha) so I figured he'd love the random action of the cypurr mouse....
