Doug, what sized cages were they in? Were they plowing through it and getting it in their mouths while cruising? Mine don't burrow or rub much so besides feeding, which can be very active, I can't see mine getting a mouth full. I know when they were all small I was warned about such issues but with my group I have not seen any problems. When they were hatchlings I used paper due to the damp frozen thawed pups.

Jason, I think everyone that has them is trying hard! The breeding part is the easy part! I am also trying to build up a decent sized breeding group. It's the space and money that's also hard!
