Oh, cardboard mixes are a good idea! I'll look to see if I can find any other brands of it if Walmart doesn't have them anymore, or see about making my own (I've got a lot of boxes laying around). The hemp mat looks promising, so I'll give that a try next, maybe with bits of shredded up old blankets as nesting material? Toilet paper only works as long as it's still in large pieces. Once it becomes small shreds it gets stuck in his fur as well, and since he takes it deep into his little nest, I have to tear it all apart to get the little shreds out, which isn't ideal.
