I keep my boxes filled very deeply with the clumping variety.

My two boys have excellent toilet coverings, although cleaning that area on their bodies is not very high on their agenda. It is OK, because Meowmy has plenty of baby wipes just for the guys.

Debra (blk/wht) refuses to cover her eliminations, although she scratches like crazy at the sides of (covered) box, of course to no avail. Sometimes she will SPRAY/pee so that it runs down the side of the box . . . how lady-like . . .
