I JUST had my first major chew out tonight. I was cleaning some tubs in a room where I still have a whole bunch of Sterilite grow out tubs. I pick up one of the tubs to dump the shavings and I see a GIANT chew hole in the side. The hole is about two inches wide and six inches long. Unbelievably, none of the rats left the tub.

I'm building another two racks tomorrow LOL. I'm ditching the Sterilite grow outs completely.
