yes boy mice smell more stinky than girl girl mice. i know this because of experience. my sister had a boy mouse and then when it passed away she got two girl mice and it did not stink as much so if you are going to get a mouse get a girl Boys tend to be more cuddly, but do let off more odor, but the difference is not huge enough that it should affect your choice in pets. Both genders make good pets. While girls smell less, they're less cuddly. There's a pro and con to each.
