They are doing great this is their 3rd week and no issue at all.
No chewing (too busy with their wheel I guess) they eat through the hardware cloth just fine, seems to be working out.
I think one my next project will be to make a rack for them using the Rat rack design posted here, using 1/4 or 1/3 hardware cloth instead of the 1/2 used for regular rats.
The best with the tubs I am using is that I can put a small (4.5 inches) wheel in there to entertain them.
