I still find it kind of a waste when you can just go buy a rat? I really don't see them getting to the size I want in two weeks especially after countless people are saying its take longer then that. With rats I just add a little more pine and make sure I clean every 7 days and it really doens't smell that bad. And its funny how a lot of you say theres no smell. Then there are people that say the deffinately do...? Personally I don't get caught up with it. The only reason I think they are good is for problem feeders, but what I don't get that either. If they smell less like all you say then wouldn't it be just like any other rodent? When I feed mice to some of mine as feeders the feeding response is usually way higher due to the musty mouse smell, but with rats its a lot less of a smell and usually take a little more to entice them so wouldn't it be the same for these guys? Its all hype and your all nuts haha jk
