Can You Put A Baby Guinea Pig In With An Older One?

Yes, this can often work quite well. Older guinea pigs are less likely to perceive the smaller, younger guinea pig as a threat and so pairs like this tend to get on relatively well. Keep a close eye on them for several hours to ensure that they're getting on well, and have a look at our section on introducing guinea pigs for tips on doing so as safely as possible.

As well as watching them carefully over the next few weeks to make sure that the older guinea pig isn’t bullying the younger, it's a good idea to be aware that female guinea pigs reach sexual maturity sooner than you’d think. Sows can become pregnant at just five weeks of age, which is highly dangerous.

I have 2 baby guinea pigs and they're in a separate cage than the adult female but her cage is bug-fested and need to get rid of it. Can I put her in the babies cage? They're all girls btw.

My guinea pig just passed away and I dont want the other one to be lonely. The new guinea pig is probably going to be a baby. Can i put them in the same cage together with and adult male?

So, I have a male adult guinea pig and a baby guinea, but it's old enough to be separated from the mother. Is it safe to try to get my male adult guinea pig and the baby male to bond, so I can put them in the same cage?
