Kelly,
I don't have the magic solution to stop the peeing, but, hopefully you realize this IS a temporary situation. I know with Binx, there have been more than one time where I said, "That's it! I can't take it anymore. Too many animals, too many problems." It does pass. I would confine Phoebe to a crate, with a box, for awhile. I know Jen L had this problem, and I forget how many weeks she did it with her kitty. Then, obviously, you have to address the issue with David. Either he stays with you, and deals with the fact you have cats, or he doesn't. It isn't fair to you for him to accept it sometimes, and then be resentful others. You could have a far worse 'problem' then being too compassionate about cats. Please hang in there.
