Now you've had your pet rats for quite some time and you have realized that you are hopelessly addicted. Don't worry, it's perfectly normal and happens to the best of us.

Well, there is no guarantee that any given group of rats will get along, but you won't know until you try. More times than not all goes well with a little time and lots of patience.
