Well bunnie comes inside a lot now (with it being -5+ degrees out at night) she is not yet litterd trained (i keep trying lol) but i was thinking about useing piddle pads made for dogs to help teach her to use a litter box. I have used piddle pads before but i was always there to supervise while she was freeromeing. But this is the first time not supervised. So i was wondering are these piddle pads safe? (like if she maybie chews on it) http://www.drsfostersmith.com/product/prod_display.cfm?c=3307+32+21670&pcatid=21670
