LOL! Braingirl is absolutely right! My dwarfs have tossed their bedding all over the place and just bury themselves as far under the substrate (Boxo) as they can. So there's toilet paper all over the place
. I've decided not to put it in anymore and just leave them with the Boxo. It is very much up to the individual hammy. No way can I figure out what they'll do LOL.
