New rat rack i built with the mortar tub is ready to be filled.

top 3 is using .5 screen and bottom 2 .25. I set up the 2 .25" screen as i was putting ASF in there to breed but ended up selling them all off today and no longer wanted them.

So my questions is can rats still eat though it, im sure they can as their teeth arent .25 wide. Also thought about putting mice in the bottom 2 but idk if tubs will be too high for them to reach the valve.
