I raise rabbits and am starting to raise quail. Cages are fairly easy to make but I'm always at a loss for what to use for a litter pan. Usually the litter pan ends up being made of wood, sealed with bathtub caulk, and coated with several coats of poly. This works but I'm wondering what others are using. I've considered aluminum baking pans put they are usually too small and flimsy. Any suggestions?
