A female can have babies any age above 5 weeks old.
I have a female that had 2 babies before I got her in 2000 so I am assuming she is about 14 or 15 years old.
they have to be as old as your mama
before 5 moths old
female hamsters can have babies any time after there a couple of mounths old
Most can if they are old enough
As early as a couple months, even weeks! Unless you can find homes for many, many, hamsters, I would suggest not putting a male and female hamster together.
when your female sex cells develope or when u start seeing ur period
4 months old
Only the female cares for the babies. They stay with her until they are about 6 months old. Some will stay with the mother through the winter before they leave on their own in spring when they are about a year old.
Female killer whales become sexually mature (can have babies) at about fifteen years old. They have about one baby every five years, and can breed until they are about forty years old, meaning that a female will have around five babies in her lifetime.
Usually they do, though you have to be carefull around the mother until the babies are about one month old.
