Ok as you already know they are pretty expensive. Anyway I wondered if anyone uses anything under there pee pads as they are not very thick and absobent like the packs always say. If theres allot pee theres allot of leaks. I was thinking of getting like a thin sheet of plastic or wood to place under the pads to make it easier to clean and not leak all over the floor. Does anyone else do this or what else do you do?
