Thanks for posting.
Are both your chins still friends now or did they have a falling out?
Neither technically. They got along great. So great that i was shocked when my ferret was out to play and found a baby chin, that i didn't know existed, underneath the refrigerator.
After learning more about it, i knew chances were she was pregnant again. So i let them stay together until it came close to a possible due date. But i had to keep them separate after that. No more babies. She now lives in a cage with her two daughters. And he lives in a cage with his son.
But while they were together, they got along perfectly. In fact i have to have fleece covering in between there cages now. He has heart problems, and he gets so worked up when he sees her. So i have to make sure he cant see her at all for his own health.
