I don't really have anything to add at the moment... just thought you may need a ((hug))..
Thanks for everyone who has been helping and reading <3 it means a lot to me. We really want to help solve the problem. I've heard of people going as far as putting their pet to sleep, if they couldn't get them to stop urinating, and that is unthinkable to me.. While in the pet store, someone overheard our situation and said "And you still let her in the house? I'd give her one of these.." and simulated a boot kick out the door. I love her and want to help her stop doing this.. If we can't stop it before the baby comes, I don't know if we can keep her. And we've had her all her life. I can't have her urinating on his things, or just around the house in general. At the moment it's isolated to the couch, but what would stop her from going on his bed, or stroller or carseat once they're brought in? Gah.. I'm just rambling now. I'm so stressed about this.
The food idea is one I've never used, but it makes sense. I'm really hoping the Feliway will do the trick.
