I have a young male degu that I've had for a little over a month now. I'd like to get him a friend, but I'm not sure what gender to get. I've read that male degus often have issues with each other if they weren't brought up together. I would be interested in raising some degu pups, but not more than one litter because I'm kind of afraid I wouldn't be able to find homes for them, so I'm unsure about a female. What should I do?
