would these work for a rodent rack tubs ?

ok I builda rack last summer and have a chew out problem wit hmy rats all my tubs have been chewed out of no, I got toys ,food and woodblocks in the tubs but they still chew out. I hate to scrape the entire rack cause of thisbut I got looking and wonder if a metal tub(s) like these would work for rodent tubs?

They about the size fo a small tank ( which really is prolly too small but I not seen anything larger at lowes ( not checked home depeot yet ) but do you all thing these could work for keeping rats in for breeding ( I know really small I like ot see if i cna find larger ones ) or if i have to ralk to my uncle and see if he can weld /make me some tubs out of some light metal or something that won't chew so easy.

I don't see why they wouldn't. I raised rats for a while in the big metal stock tanks and they worked great.

Did you scrap the rats that were chewing?
