I used that same setup when my Dumeril's boa was still on mice. It works out good for breeding mice but be cautioned: if you keep large constrictors it is very easy for them to get inside! My Dum got out one night when I was at work and slipped inside the middle drawer,then proceeded to eat a mamma mouse and all 8 pinkies! A frantic search of my apt. turned up a fat and happy Dum inside the the drawer! It was quite an interesting shock. Otherwise it is a convenient set up for breeding mice. I had great success using it for mouse breeding,but then my Dum moved on to rats so now I breed rats. Best of luck with your new setup.
