Hey guys,

I've posted earlier that I'm somewhat between cages and looking for something more secure. My interim cage is a Sterilite bin with clasps on the side. Looks like this but shallower:
Tonight, I noticed he was able to push up the lid maybe about a centimeter from its resting position. I don't think he can escape, but I'm worried about possible injury from his shenanigans. Anyone else have this happen/how to make the tank more secure?
