The other day I thought Crash and Burn needed more exercise. One of the problems I have with them when they play is that they spend a lot of time stalking a toy and I don't have the patience to hold or move a toy for them. While I was picking up some food for them, I saw a toy could be used automatically. All it needed was some batteries and I could set the timer for it to move for up to two hours.
Of course, the day I brought it home they practically ignored it, but today I caught Crash playing with it. I turned it on and watched her. Of course, I also had to take a video of her playing. This is how she gets her exercise.
I had trouble downloading the video, but you can follow this link and see it.
