Nice looking 3-some! But from personal experience, I would not use those Sterilite drawer systems. They have two many angles that the rats will be sure to exploit and you'll end up with a few rats roaming the house before too long. I used Sterilite and rubbermaid bins for 2+ years and even then had chewouts. I have since put mine into a rack system. Anyhow, if you are going to keep them in that setup, get yourself one of these
