Hello ,I'm Zack and I've had a male guinea pig for about 7 months now, before it got too old I felt bad that it didn't have a buddy. So today I got another male. The new guinea pig is very young (2 months) mine that ive had is 9 months, I have a slightly large cage that I could totally block off half and they could still smell each other and see what each other are doing, as well as I have another cage for the new guinea pig. Would it be smarter to keep them separate for a while and have them meet a couple times to get used to each other, or should I use the large cage and block half of it?
