I use antislip mats just like the ones for bathrooms or showers with woodchips beneath. This way you can clean pellet while pee goes below into the woodchips so its modular and easy to clean. My Cage is about 5f x 10f (1,5m x 3m) opened for free roamneith another Cage beneath the table 1/3 od the big one, and it take me about 20 min to clear all of it.
