what to use for cage base to go under x pen and over carpet. when I open the large dog puppy kennel I've converted into a rabbit cage and let him out into the xpen what can I use to cover the carpet under the xpen? he will stay in the kennel at night but it will be left open during the day so he can hop around the xpen.... Kai will not be able to run free through my apartment per the apartment guidelines and I won't leave him in a "kennel" all day. I can also block off our small kitchen and he can run around in there no problem. but I'm concerned about our carpet under the xpen when he'll be out and about during the day (able to go freely between his "kennel" and the xpen). I'm concerned about damage to the original carpet. I've thought about purchasing a large living in room rug (not decorative) and play puppy pads under it...would this work? What would you recommend for a base? Or that stick on tile or maybe linoleum...not sure how I would lay them down I suppose of a piece of wood...what wood would be good to use to stick tiles to or linoleum?
