Obviously, you need both sexes to breed and have babies. Keep the male and female separate after breeding.
If they are brothers or sisters
Personally I think that male hamsters have a nicer temprement and are less teritorial than females. well can you be a bit more clear ?
They will do both. Both. They will first mate, and then the female will kill the male.
It depends. Syrian and Teddy Bear hamsters will kill each other if they are the SAME gender , even if they are related. There will be less fights if you put hamsters of the opposite gender together to mate. Dwarf hamsters live in groups, so female dwarfs and male dwarfs won't attack each other and will have babies peacefully.
Only if you don't mind them having little hamsters.
They will reproduce rapidly if the female is in season, otherwise they'll fight and may end up killing eachother. Hamsters can make armies of babies very quickly.
All animals are territorial creatures. Hamsters are more aggressive animals when dealing with the same gender. If you have two male or female hamsters in one cage, you are begging for trouble.
If you do they'll breed. Be ready to deal with that, or keep them separated.
Yes, as a male and a female hamster reproduce the same way we do. The male hamster inserts his penis into the female's vagina, and ejacualtes sperm which fertilises with the egg(s) to produce offspring.
I have read that a female hamster's hormones kick in every couple of days. This makes them very mean weekly. If I were you I would go with a male. You are much safer on getting a nicer hamster if you get a male. I would recommend a Syrian hamster. They are the nicest of all the hamster breeds. DO NOT keep them in the same cage. Syrian hamsters DO NOT get along with their own breed!!
Unless they're sprayed and neutered they'll breed if you do. This would be bad if the hamsters are closely related. In other words, yes it would be fine to put a female and a male hamster in the same cage.
its likely they will just breed but the male might attack the babies and if theyr syrian hamsters they should be separated because they will fight
