Need advice for my piggies cage.?

Well, immediatley stop using the aspen chips or any sort of wood chips as these fragrented chipis can be bad for the 'pigs' and can even cause lung failure and other problems. i would stay with mabe shredded ink free paper and using the carefresh (i'm asuming thats the one thats like shriveled up hardened toilet paper, i dont know how to describe it). but please do not use wood chips. i think the pool is a great idea. just make shure there are no shap or loose edges or pieces they could chew,choke,hurt themselves, or even escape out of.
