Every storm drain leads into a sewer, and it’s very easy for rats to nest in one to escape the cold. They absolutely would do the same in the catacomb (it’s an ossuary, not a catacomb, and 99% of it is really an old quarry with no remains at all, pic rel) but there aren’t many easy entryways, even for rats.
But all it takes is one errant rodent to fuck up your food.
