excersize ball

[Jessika]

I've actually heard that guinea pigs shound not be given balls OR wheels because they could create back, feet or toe problems!

I heard the same thing. Maybe as long as the ball is more than big enough it would be ok.. what size ball is she in?

I heard that they are bad for gpigges backs too.but if she is having fun,the ball is huge it propally is ok my advise check with a vet
i am not a gpiggie person ever thorw they are very cute and sweet

If you go to the VERY bottom of that page, it states that both wheels and balls aren't very good for pigs.
