We supposedly bought 2 female mice and one turned out to be a male. We have enjoyed the process of having baby mice but find ourselves in the difficult position of people not wanting the males. Pet shops are happy to take the females. I would appreciate any advice. We don't want to be left with a whole lot of males either. Thanks.

I don't know if it's the same everywhere but in my town you can put it in the newspaper that you want to give them away...

Thanks for that. The pet shop we bought them from were happy to take them all back. We kept two females. I taught myself how to sex them from the internet so definite we have two females now. It was nice of the pet shop to take responsibility. Thanks for your answer.
