at the moment, I have one Guinea pig after the other one had to be sent back to the shop, and very shortly I will be getting another Guinea pig so that mine will have a partner. To make sure I'm ready can u plz give me tips on things such as how often I should get them out in the neutral zone and how long for, how long until I should consider putting them in the same cage etc. P.s the one I currently have is a male and will be 2 in a couple of weeks and the one I will be getting is also male and is 3-4
