I was at the local pet store and stumbled on the most amazing toy ever, the 'Ball of the Wild'. It's a ball that can be filled with treats and makes squeaky mouse noises as it rolls around. I've been looking for a toy like this for years!
I brought it home, ripped it open and proceeded to stuff it full of Greenies. (The treat hole is small so I had to break the treats into smaller pieces for them to fit inside.)
Rufus had a bit of trouble grasping the concept of this toy. When I first stuffed the ball with treats and set it down, he ignored the ball entirely and followed me around expecting me to give him the treats myself. I put in some fresh catnip and then he understood, quite quickly!!
He's got the crazy eyes.
Rufus doesn't care much for the mouse noises so when the batteries run out, I probably won't replace them. I think this is a superb product and really love that Rufus has to exercise his brain and body to get to the treats.
