We'll just wanted to post a thread on what you guys might suggest as an outside rat breeding shed alternitive. I currently have a 6 concrete mixing tub rack for the rats and 2 glass aquariums for some mice. I had to bring the rack and aquariums inside from their outside location for the winter. Now my prob. is this the smell is getting to my wonderful fiance who has been really nice so far but now is starting to complain about the smell. I clean their tubs very frequently, but the laundry area is just a door away from the rodents. I was hoping to get some input on what people use for a rat shed. I have seen several postings with rat sheds and this would be no problem for me to build-the only problem with these ideas is that I live in western Pa. and out temps thru the winter sometimes get extremely cold for what I need to maintain a good temp. for breeding (70 degrees). So with this said is there anyone in a colder climate that uses a shed and if so what do u do to keep temps. up. Also pictures of inside would be very helpful in designing a structure. I am going to try to get thru the next few months with the setup I currently, just planning for when the weather breaks. Thanks to all that reply.
