Hi all! In the future, I would love to own a rodent of some sort, but I’m not sure which one would be the best. I love rats, hamsters, and guinea pigs. However, as of right now im unable to any of these since we move places a lot, but in some few years or so I would love to get one (or a few). I know hamsters are solitary, but rats and guinea pigs need to be in groups. Which of these would be the easiest and most cost efficient?
