Query: Good For Exercise

My kitties love chacing bubbles, and it's great exercise for them. But even though standard bubbles are labeled non-toxic, it bothered me that they were essentially ingesting soap. I really didn't know what it would do to their sensitive stomachs. So I was happy to find these which are created especailly for animals, and therefore safe to be licked up. The catnip is an added bonus...again more motivation for them to move around and play (they're currently on a diet and exercise program...heh). Fun toy!
