"Can a human exercise ball be punctured by timothy hay?"
Google cannot seem to handle this question.... Human exercise ball (fitness ball) does not exist with hay products. So I am wondering if anyone has had a pet with hay products and live in cramped spaces where hay can come in contact with this human exercise ball (fitness ball). Just don't want to blow it up to have it pop! It came as a set of items and I am sure I can use some of the other items without this. Thanks
