I have heard that temperature and light can cause stress on rats which decreases their breeding potential. What temperature range is appropriate for a colony? 50-90°? 60-90°? I just built an 8-shelf breeding rack and the Edstrom automatic water system is to be delivered tomorrow. These guys are going to be in my patio storage closet! Lol.. I know, I know. Far from ideal, but I have to work with what space I have and I really don't want my place to smell like an ammonia factory..

I'll post pictures and a link to the design later today hopefully.. I think it should be quite an efficient system..
