Hi bella-again,
We had a cat that just peed literally everywhere even though she was tray trained. We had to persevere with the Urine Off (we found it really good) for months but eventually after ripping up the carpet, cleaning thoroughly, repainting the room and the floor before laying down carpet tiles, eventually, did I say after months, stopped her from peeing on the walls and floor.
The black light will help you immensley but perserverence is very important. Cami was so stressed she used to almost live on my shoulder and would not tolerate visitors to the house. She is not tolerant of our other cat because when Eddie comes inside she hisses at her every time. Cami does not go outside, she is too timid.
I bought a packet of catnip and spread it light on the carpet and let her eat it and roll in it. We found that helped her. When she gets 'upset' we just throw the catnip parcel I made at her and she calms down really quickly.
Another thing we did was to put small bowls of water and food down where she peed, after we had cleaned the area, and found that after a while, she stopped going to that spot.
Good luck with your fur baby, it is worth it in the long run.
Gentle pats and belly tickles to your cat.
Di
