Help...male mice

[Nikaleeona]

My flat mate cam ehome with 2 gorgeous male mice 2 weeks ago however is no complaining that they smell. I clean them out every other day but was wondering if there is anything else i can do? I have told him that he should have got female ones cos males smell more but now he is threatening to get rid of them. My 15month old DD loves them and the first thing she does when she wakes up in the morning isgo and see the mice. Also, one of them is a buly. He chases the other one around biting him so much so that the other stays in the bed all day and doesnt dare come out cos he gets attacked, but they are both really friendly and very tme and have never biten yet. I would really appreciate any advice anyone has as i love them to bits, they're so cute and really dont want to get rid of them. I've kept mice before but they were females so didnt smell anywhre near as much.
TIA x

Can you get them neutered? I know cats don't smell once they're done, but don't know too many mice.
