I use human disposable inco pads in my guinea pig cage. I find they're more absorbant than puppy pads. However, both will do the same thing. I just cover the pads in a good layer of hay. Fortunately the wiglets never chew them as they're plastic-backed and I'm not sure they'd do a bunny any good if they decided to eat them. However, if you don't have a chewer, you should be ok.
