Help about putting mice together when they have been alone?

It is extremely unlikely you will have any problems at all re-introducing mice this young. They are communal animals and -=want=- company.

I would go buy the last little girl and bring her home. I would clean the cage out very thoroughly, clean the water bottle and food dishes as well. If it is an aquarium you are keeping them in, have a margarine dish handy (to cover one of the mice if they seriously fight) and put both mice in the tank at the same time. Do not leave them alone until you are positive they are not going to fight.

If you are using a cage instead of an aquarium, it will probably be easier and safer to introduce them some place more accessable. I get a lot of use out of my bathtub for my critter introductions :). Lay down an old towel in the tub and bring your margarine tub (to cover one of the mice if they start seriously fighting). Put both mice in the tub and watch them. They will probably squabble some as they get acquainted, but there should be no panicked squeaking (you'll know it when you hear it) and long chases around the tub with one always being chased. If they are chasing eachother back and forth it's fine :).

If they do fight, try a split cage introduction for a while if you can or put their cages very close together and try again in a few days.

As I said, it is extremely unlikely you will have any problems at all at that age, just trying to help prepare for 'worst case scenario'. I have added adult mice to established colonies without problem.

Good luck!

Generally Mice are pretty social but the cage HAS to be big enough for both, also it needs to have enough hiding spots for both of them to get away from each other. They are going to fight to establish the dominance factor. Is the pet store and YOU good at sexing mice? at that age they are hard to tell, since the males testicles dont always drop till early. I would wait till you are positive your getting another female. Then it is a slow and painful introduction. The important thing is you have to let them fight it out. If they are constantly fighting to the point of blood shed, and the one will not leave the other alone... then you need seperate cages. Though they will fight for a day or two to establish the pecking order. In this the more submissive will alow the dominate female to pick on her by rolling on her back or taking most of the blows give with out much of a fight. They will determine this pretty quickly. If you see blood, its most likely the one is biting the others tail... as long as shes not biting any other parts it should be ok.

Mice, particulary females, are exceptionally social. Females rarely fight, but upon introductions do chase eachother around in a seemingly violent manner, but this is part of establishing dominance. One week is fine, it gives her hardly the time to "forget" what it's like living with company.

There is a process of introduction to follow through. You never put a new animal into the old one's cage. You need a second cage to start out. It doesn't have to be fancy, you can drill holes into a rubbermaid container and keep the new one there for a while. To start out, just keep the two cages in the same room, near eachother (not too close). It's best to drill holes in the side of the rubbermaid so they can smell and see each other better. After a few days of this, they will get to know each other's scents better, and you can eventualy put them in the same area. ONLY do this on a neutral area they both do not know (like a bathtub).

Edit: To add to that, learn before hand how to sex mice, and do it yourself in the store to ensure you're getting a female. Don't rely on the pet store employees to sex for you, they are often mistaken.

Female mice are usually ok to put together as i have done this myself.. Male mice can only be kept together if bought at the same time from the same litter that hasn't been seperated.

Considering they've only been apart for a week, I don't think it'll be an issue. Female mice are social and get along well with others. There might be a little dominance fight but it won't be anything serious, and before you know it they'll be snuggling together. :) Good luck!

No. No. No. No. diverse species. diverse nutrition desires. diverse communication. diverse techniques of communities. reckoning on the hamster, they could even could desire to stay on my own, different than for ALL animals, which contains mice. Hamsters could desire to truly kill mice.

they were together once but i dont know how long their memories are, if u are going to buy the other one anyways do have an extra cage prepared just incase.

gadualy do it like one hour every day first week 2 hrs every day 2nd week and so forth if they fight they're beyond hope give them a couple chances 1st

I had two hamsters. I put them in the same cage. THEY STARTED FIGHTING LIKE CRAZY! The whole night you could hear squeals and squeaks. I advise you to buy a separate cage or not buy another mouse at all.

cant help you i keep my mice in the freezer
