Helloo!! So I need FLOORING ideas because right now im using a bed sheet and because my floor is wooden in case he spills his water bowl inside the cage under the bed sheet I am using a nylon sheet (i know it is bad if he swallows it, i am always watching him) and i want to change this nylon sheet with something else any ides? (I am thinking of a foam floor protector mat but i am scared if he chew it) ALSO i am currently using this hay rack and because I recently changed his cage into a x-pen he is not using the hay rack as he used to any ideas what to buy or make as a hay rack for this x-pen
