Hi everyone! My son and I have two ferrets, a 6-month old sable girl named Skipper and an 8-week old cinnamon boy named Jake. Jake has only been with us for a few days. Our problem is that we are unsure as to how to tell when they are just rough-housing and when they are fighting. Skipper seems to be constantly biting Jake, but Jake doesn't seem to mind it all that much--just rolls over and tries to jump on Skipper. We want them to have all the fun they want, but can't tell when they aren't having fun. Does anyone have any ideas? Beth, Kevin, Skipper and Jake [Posted in FML issue 3489]
