Hello all,

I have a quick question that I am hoping someone may be able to help me with.

I have recently had issues with baby rats not surviving. I don't feel the need to go into detail about this but I have decided to build a maternity rack in order to help with this. I feel good about the plans I have made except I am trying to maximize space and am wondering how much height I need to have between the bottom of the tubs and the next level. I will be using a gravity fed watering system and will install it as soon as the parts that I need arrive.

Thank you for any help you can give.
