Cage Carpet protection options for under a C&C cage.

Greetings,
I recently moved to a new home and I have placed an order so that I can increase my cage from 3x2 plus 1x2 loft to 5x2 plus 2x2 loft. I'll be moving the cage from a room with wood floor to a room with carpet but carpet poses a whole new problem for cleaning. A poop or two always finds its way onto the floor not to mention the hay and whatever else that they kick up from the cage. With wood floors we can easily sweep but with carpet that becomes a problem. It is also brand new carpet so we really want to keep it clean.

We thought about a floor mat like people use for office chairs on carpet but they don't get big enough for a 5x2 cage. The few that are big enough are $100+. A tarp won't fly because it will be in a living area and would look sort of trashy. I thought about one of the heavy duty shower curtains but don't know if that would look acceptable or do the job.

What solutions have other folks tried? I must be searching with the wrong keywords because I'm sure there must be existing posts on this topic.

Thanks!
