Introducing a new Guinea Pig to old Guinea Pigs?

[Annabel]

I have two male-7 month old Guinea pigs. I have had them for about 2 and a half months now, their cage is getting a bit small for them, so I am going to build them a two-story C&C cage, where they would each have their own level, but they would still go out in their exercise pen together. I am also thinking about getting another male Guinea Pig. In which case I would make it a three-story C&C cage for them, where they would all have their own level. Cleaning their cage isn't a problem, neither is vet expenses, or supplies, and food.
Anyway, If I did get another male Guinea Pig would I need to introduce them to my other Guinea pigs? Or could I just let them live separate lives? But if I did, would the old Guinea Pigs smell the new one and get all mad? And go "crazy?"
Thanks,

Will my Guinea Pigs not like me anymore if I get a new Guinea Pig?

As long as he is in his own cage and only with the others in the play pen it should work out OK. May i suggest though before you put them all into the play pen that you clean it with vinegar and water so it does not smell like "theirs" to the old guys and they feel they have to defined it.

There was a case on answers must a few days ago in which i got best answer for where they introduced a third guinea pig and the lost total control of all three, it in just animal instincts, they start to take on herd behavior. You are however talking of not housing them together so i think you may have a chance.

It is my personal opinion that ALL piggies should have a buddy. They are very social animals and do best in pairs. However, when dealing with boars, this can be tricky. Because you already have two bonded boys, bringing in a third one may cause problems. Or it may not. It just depends on the personalities of your two resident boars and the personality of the one being brought in.

If you are intent on doing this, I highly suggest finding a reputable guinea pig rescue in your area. They are usually really good at helping you find a good match, personality wise.

If your new C&C cage has levels that prohibit your two boys from seeing each other, you may find that when you put them in the exercise pen, they might not get along. Guinea pigs have fairly short memory spans, so unless they are together (seeing, smelling, playing) all the time, they forget they know each other and may require repeated RE-introductions each time you put them back together. I hope that made sense.

There's no doubt your two resident piggies will detect a new piggie in the room, but unless its a female, they won't go "crazy".

Good luck!
