THANKS ALOT! That is what I was thinking about last night but everyone else had the tops with the mesh on it never thought about the sides.
But I don't have the room for that big of a tub, haha. I will down grade to the 32 qt tubs (the ones at target are more tall than long) and just do the same thing and have a 1.2 rats. Sounds like less work to and don't have have worry about chewing and escaping.
