I've owned three ferrets for a while now...Trouble, Ruby, and Sven. Trouble and Ruby were adopted first, then Sven a year later. I recently adopted a 4th ferret, a male around ~1 1/2 years old. He has been an only ferret his whole life so he wasn't really sure how to react around my three. He has adjusted really well with Ruby and Trouble, they play and sleep together now with no issues. Sven, however, HATES the new guy. He viciously attacks him, violently shakes him, and has ripped out hair and broke skin. The new guy screams and has pooped on the floor in fear. He makes no effort to defend himself, and I don't think he even knows how. Even just holding the two ferrets, one in each hand, Sven has tried lunging to bite the new guy. I've tried switching bedding around. I've tried giving both of them a bath so they smell the same. I've tried bitter apple on the new ferret's neck. Also tried ferretone. Nothing seems to help. The second Sven realizes the new ferret is out, he goes into hunt mode and will not leave him alone. Is there any hope for these guys ever getting along?

Sometimes it takes a while for them to get along. My first ferret was jealous of our second who came along 9 months later. I switched bedding so they could get used to each other's scent. Gave them a bath so they smelled the same. Also had only supervised playtime. They will establish a pecking order. The usual thought is no poop, no pee, no blood no foul. If too intense they can get stressed. Through the years I've had a few that just didn't get along so I had separate play groups. My 4 right now didn't always get along but they play fine now. Sometimes it just takes patience.
