Now I have been thinking about raising mice (maybe rats) in my garage for our corns and ball pythons. I was able awhile back to look after a friends rodent rack while he was getting married. I get how to build it. I noticed that when the rack was moved to my garage that the mice realized they were in a new place and scent marked everything. Very strong odor the first week. After that they settled in and were not so bad after the first box cleaning. Yet the odor was still a little strong. So how do you keep the odor down so as not to permeate through the whole house? Also would mice and rats do well in a garage in the winter in New York? My boiler is in the garage so I could keep them near it to keep them warmer. I do not believe it gets below freezing in there during the coldest times.
