We "live" in our bonus room (watch tv, play on the computers, even eat our evening meals while we watch tv), so we knew Elvis would need a special place for his exercise pen, which meant we didn't want the carpet to be ruined in case of accidents. We bought a linoleum remnant, which happily matched the carpet. We placed the pen on top, layed out his pee pads (with the bottom of the pen on top of the edge to keep them in place) his little bed and his food/water dishes. He just did great in there until the day he began to climb over the pen. We finally removed the pen and left the linoleum with the pee pads and food/water dishes. Works like a dream!
