Well, I kept the two offending cats, apart for over a week. Last night one managed to open a door and they seemed to get along UNTIL this afternoon. I had stopped at Petco and purchased liquid (spray) calming liquid. I soaked two cloth collars in the stuff then managed to capture each cat and put the collar on. WELL. You might think I put a cinderblock on them. They are sitting (in their own room of course) and looking sad and unhappy. MOM, what did you do? I hope the new collar soaked in love juice will do the trick. I am running out of tricks. I even reinstalled the window/door to the porch!

Ugh!
