I have had Mo for a month now after I adopted him, and I have read EVERYWHERE that two makes for happier guinea pigs. So today I got a new "baby" and he's in a different cage for quarantine, but I don't know what to do. I feel like I may neglect one or the other and I LOVE Mo to death and don't want to do that. However, it sounds like he could be so much happier. And I feel like I may be getting in over my head with two. What should I do, should I re-adopt out my new one or keep him?
