I searched the archives for this topic, but only found general advice about ways to introduce new ferrets to old, and I'm looking for something a little more specific. I have two male ferrets from a shelter, Koda and Kenai, who are about three years old. I've had them for about six months, but they were cagemates for over a year. Koda, who is about half Kenai's size, is much more playful and energetic, and I thought he could use a more active playmate. So we got a 4 month old male ferret who is about Koda's size. During the first supervised play, Koda seemed to play nicely with the new guy, although the new guy was scared, but then Kenai attacked and somehow managed to draw blood on the roof of the new guy's mouth. After blood has been drawn, is it possible to get them to get along, or will there always be animosity? Does this mean there is too strong a visceral dislike among these two, or might Kenai just have been playing too roughly? Is is possible that Kenai just can't be with anyone but Koda? Right now we have our two older boys in their regular cage when they are not roaming, and the new little one in a pen next to the cage. Should I try letting them play together again? Any advice would be greatly appreciated. Thanks! -Nancy [Posted in FML issue 5316]
