I got him back to my camp, went through the three or four encounters there to fully friend him and now he has disappeared too. Last time he was there I could pet him and the response was something like "He purrs and hoots and trusts you completely." Shadowheart made a comment he would eat us of out camp now and then eat us. It's been five or 6 long rests at least since he was around, think he might be gone for good.
