I've had my first guinea pig for the last 4 years. I've always wanted to get her a friend because they are social animals. Hazel is now 4 years old (born about July 2016?), so I didn't know if she would not like a friend now that she is older. I'm new to the introducing them to each other, so any advice will help. It probably wouldn't be until February if I get another. Hazel just went to the vet for bumblefoot, so I would like her to heal before getting another. Plus I'll be down next month for a couple weeks for gallbladder removal. But would a female be better for her? I'm not sure whether to look for a younger one or try to find one more her age. Any guidance is greatly appreciated!
