So even though they urinate so little you would say they smell just as bad as mice or rats? I'm not trying to convince anyone of anything one way or another just trying to learn the facts. The main odor in my rodent tubs is urine, I clean the tubs weekly but in about 2 days you can hardly tell smell wise...especially in the maturing male tubs. That's why males are the first to go! Thus far I guess its worth it to get some and do some testing unless some fall into my lap.

Another quest for a clean odor -less down the tubes for now. My wife's gerbils never smelled, maybe I'll have to train the mice to use the potty

Thanks for the replies!
