Good because it keeps the guinea pigs from making a mess outside of the cage. The shelves come out so it’s easier to clean and the cage is on wheels so it’s easy to move around. Major drawback is that there isn’t anywhere to hang their water bottle so my husband built a stand for the water bottle from some scrap wood which works fine. The drawer on the bottom doesn’t have any guides and so can take a little patience to put back in so that it’s straight and sits in the cage right. Husband put a thin piece of wood on the bottom and glued it in to make it easier to pull drawer in and out and so the bedding couldn’t fall down behind the drawer which was an issue at first.
