Hi all! I am, after a fifteen year hiatus, a happy second-time rat parent! He was adopted from the internet, as a single rat with apparent rat aggression issues which I'm educating myself about. I an voting to give him some time to settle in and get comfortable with our family (this household has cats and the old one didn't, so I hesitate to begin rat introduction until I am confident that he doesn't consider the cats to be a threat) before building a colony. He doesn't seem concerned about them, but, better safe than sorry! I hope that being a part of this community can help me feel confident about meeting his physical and psychological needs.
