I just got another mouse on April Fools' Day, and in the cage when I got her, there was a male mouse in the cage. Who was obviously a male. There were about 40 other females in the tank, and just one boy. When I told the pet store employee, she seemed incredibly nonchalant. Now I'm wondering if she is pregnant. What do you guys think? Because she could also just be chubby.
I guess she's not. No babies for me
