I can confine Sterling to one room but only temporarily. I don't think I could keep him separate for life. And so far he DOES do better when he is in one room.
As for the feliway, I tried the plug-ins first, before the medicine, and by themselves they did not help. They are still plugged in so i do not know if they do anything or not (I have had good and bad times with them in use). The fliway spray could be helping. I was using that during the time I had no accidents and I do have to admit to slacking up on its use right before the first relapse. (You are suppose to use it daily, twice daily in situations like mine, for a month). Let me tell you, that's HARD to keep up with.
