Hi E. -
I had this problem with one of my cats a couple years ago. I tried everything! Feliway did not seem to work for us. This sounds kinda mean - but it is the only thing that worked. I would lock the cat up in the laundry room all night and day. He would be allowed out when I got home from work until we went to bed. I did this for about 8 months and it actually worked. We also pulled up the carpet in the room he liked to do his business. My cat did not do well on any of the anxiety medication. This was my last resort. I actually had an appointment to have him put down until someone gave me this idea. Good Luck!!
