Okay, I see - I think Ally has/had a separate room at Jenn's - maybe just one other cat who didn't bother Ally and vice versa.

Julie - seems to me their apartment didn't have any spare room. I might be recalled wrong.

I was thinking along the lines of someone taking charge - which you did, in a way - and showing the Alpha kitty who really is the alpha...kind of like one does with dogs, I think.

Wonder how to get that through Ally's skull? Tough love or just plain love?
