im looking into getting the FN 182 but then i dont know where to get a metal pan at the bottom/middle. i was going to use fleece but then i would have to wash it way to often or else it would stink and zooky wont litter train. so i want to stick to aspen bedding and just fill his 2 floors with that. but where can i get a metal pan? or can i make the floor of the second floor all wood? but i dont want him to pee on the wood so then i was look into making the second floor all granite but i dont know where to get that either. so where can i buy a metal pan for the first and second floor? if not then just the first floor and then where can i get granite for a reasonable price?
