Boy I wish I had the answer for you cause we're going through this ourselves. I've about had it with Leila and her peeing. This morning she stood right in front of me and started to spray on my work bag! I yelled and she ran. Between her, Mouser, Bo, and Avon there is a constant battle at our place these days. I've been considering just putting Leila back outdoors, but really hate to do this to her. If you find the right answer let me know. I wish you luck cause it's not easy thinking of rehoming, I know!
