Post 18 - 2013 Wishing my boys would get along

So I have this wonderful (most days) 15 year old blackish brown cat who curls up and snuggles tight with me, does the same to B, loves us soo much.  Yet, cannot seem to stop getting mad at us for locking him out of what he deems his room during the day, so that the dogs do not have fun playing in the bed.   How do you reason with a cat?  How do you reason with an irate man who is tired of the cat pooping outside of the litterbox and on rugs and such?  Such a fine line.  I love them both dearly. I do not want to live without either.  The cats lifespan is much shorter than the mans but both make me equally happy.  He does not leave my side when I am sick.  He sinks into me when he sleeps.  He sleeps on top of on one of us when we are home.  So why does this cat insist on being bad?????

Really hoping my solution I have in mind works.  Wish me luck as tonight is deep cleaning of many things and re-arranging to appease both my boys!
