There was post on Beagle Bay this morning saying that 4Paws has acknowledged a problem with the ball mentioned in my earlier post. There was manufacturing flaw. The hole that was supposed to be on the bottom of the ball did not go all the way through. If you have one of these, all you need to do is open the bottom hole with a pin or small nail. The company is recalling product still on shelves and not shipping any more until the problem is resolved. 4Paws is asking pet owners to spread the word to friends on how to repair the ball so no more pets are hurt. Evidently there is a message on the 4Paws website. I haven't had time to read it yet but wanted to let you all know.
