Mice are the kings and queens of chewing over time. They aren't aggressive chewers, but they will slowly chew anything they can. With as thin as those are, make sure to check for any chewing, cause once they start, they don't stop untill they get out. I had to cull my first female rats cause they were tub chewers and their babies inhereited the gene so i had to start from fresh.
Some mice are and some mice aren't chewers, but generally, they all do it somewhat.
