LOL!!! Those pictures are great!!!
I have a ball also, for the hamsters and gerbils... Odie used to fear the ball... specially when Martina was running in it cause she runs fast! Now he just jumps on the bed and ignores them... now, it the guys are out, he's just fascinated with them. 8) I even have a few pictures of him interacting with my hamsters and sticking his head in the gerbil cage (and I have a picture of me holding a baby gerbil and him looking at it, but his look is definetively "lunch" in it!!!)
