What happens if two baby mice breed with each other?
If the baby mice are brother and sister, and shes does get
pregnant,the baby mice will not be deformed or anything.That's
called inbreeding and its not really healthy,but a lot of people
still cruelly do it just to make money.Always ,always ,ALWAYS
separate the males and the females!They will breed no matter what
relation one has to the other.And its a good idea to separate the
baby girls and the baby boys once they are eating solids and acting
like all the other adult mice.And make sure the moment the moms
giving birth or u think its gonna give birth that you put ALL the
males in another cage,INCLUDING the dad.Theres a good chance the
males will eat the babies.If you need more information look up "how
to care for mice" and you will find lots of really good sites on
how to care for them at all ages.
well they might have babies or they might not it all depends on
exactly how old they are or if they are brother and sister
