Mice and Racks

[Stewart_Reptiles]

What do people use as mouse tubs? I saw someone using 6qt tubs but those have ridges and seem pretty small. I was looking at these https://www.amazon.com/Medium-Cat-Pa...s=pet-supplies
But I'm not sure if they are flat, as almost all of their tubs are ridged on the inside.

Usually cat litter pan with flat bottom and no groves or ridge anywhere which are becoming hard to find but I believe publix still carry them.
