I have one boy guinea pig and I've been trying to convince my parents to let me get another so he's not lonely, and I think my mom's warming up to the idea. She's started asking me questions about what type of guinea pig I would want, if it would be a boy or girl, et cetera. The nearby shelter spays/neuters almost all of their guinea pigs (if they're not, they'll tell you) and I want to eventually get a girl guinea pig from that shelter. However, would it be OK to have a spayed female with an unneutered male? Wouldn't he keep trying to have babies with her? I was wondering if I should neuter my boy as well to make sure this doesn't happen, because I don't want him chasing her around trying to have babies with her. However, I don't really want to put him through a surgery unless I really have to. What should I do?
