For those of you who have animal plastics T10 or comparable cages, do you use the sliding doors or swing doors? I like the idea of the sliding doors but I am worried about the grooves being difficult to clean. The idea of the sliding doors seems better to me just because you can get a little more access. The drawback would be that I would need a lock on the cage then whereas with the swing doors a lock is not needed to keep them closed. Any input?
