When I adopted two of my female piggies they came with a large pink exercise ball. I know it is not suitable for piggies or rabbits to run in, but I was wondering if I took the end caps off and suspended it maybe 3 or 4 inches above the floor of the bunny cage, would she get in it and use it as a hidey? I got the idea from the gallery and a picture Jdomans posted of a hidey for her chin. If not, I'll just get rid of it.
