Yes. Rats are social animals and do well in groups. They do fight at times and if there is a bully in the cage, that rat should be removed from the group. In many cases, the bully will be a male rat.
Female rats from different litters are likely to get along well. You shouldn't have any problems. Do offer enough hide-aways and beds that they can get away from other rats if they so desire. In most cases, the rats will want to be together but they should have options.
Yes, just make sure they are same sex unless one is altered. Also, you should quarentine the new rat for at least 2 weeks to make sure they do not have any illnesses. I would recommend doing introductions slowly over the course of a few days before letting them live together in the same cage.
I don't think you can. male and female rats will mate. Even brothers and sister rats will mate with each other
you put a female and a male together but watch them incase they fight!!!
You can put a male and female rat together if you want them to mate and have babies. You could breed any size of rats.
They will have sex... & more sex. untill babies are born. Then more sex. That's the only relationship they will have (unless neutered). They cant live together and not breed, unless the male is neutered or infertile DONT put them together other wise. There are already so many unwanted rats.
no
You put them together when the female is full of eggs, and when the male builds a bubble nest.
You put a male and a female together. Take the male out after a few hours, and your female will have babies.
Well it depends on how small your small rat is, but usually yes, it would be okay. But you can not put 2 males together (They will most likely fight to the death), or a female and a male unless you want them to mate (Because they will make baby's together).
You get a male and female of one pokemon; male and female pikachu. Then put them in daycare together and walk around. That or with a ditto.
The answer is to avoid doing this. If you put a male budgie and a female budgie together, they will mate.
You put a male and a female together.
you put a male and female together and you wait.
No you cannot, only if you are breeding them and the female has eggs. Otherwise the male will eventually kill the female. 2 females can live together.
