We did put Satchmo's food,blanket,toys,water,litterbox and his brothers into their own room where I kept my things at first. We did not try the scent-exchange idea though/never thought of it. Now at first all the cats were doing fine except Satchmo was the aggressor until the tables turned on him. We've been carrying Satchmo into the spare bedroom a couple nights a week so he can sleep w/me and his two brothers (who get along great with Sallys cats). During the day/and night too we put food and water up on one of the middle shelves of the condo for Satch. We also place a litterbox beneath the condo. I make sure he gets alot of attention every day. I'm going to try the towel-scent idea to see where it takes us. Until then I will continue to beleive that like people, cats are who they are and can't change some things about their borne identities. If Satch was more sociable like he is with his brothers,life would be so much better for him ....but he has this built-in angst about himself when it comes to cats other than Rollins or Yikes ...and you know the rest. I really think that in order for him to be secure and happy that he needs to be alpha-one and thats just how he's built.
