Hi m hoping someone can help me coz i am at my wits end!

I have a 4, nearly 5, year old female moggie who pees wherever she wants!

I recently moved in with my boyfriend, well about 2 months ago, but before that lived with my parents. When I got my cat I trained her by the book. I bought the ktty ltter tray then moved it outside after a while and then eventually took it away and all was fine. Then we started to find wee and poo everywhere! Under computers, ontop of the fridge under floor boards! You name it she weed or pooed on it. I scrubbed everywhere wth disnfectant put citrus scents down to try and discourage her but she kept doing it. The annoying thing is she wont meow or ask to go out, I have watched her just stalk over to an area and wee after a nap. Even if she spent all night out she would come inside and do her buisness. Thinking back i put the behavour down to the fact we got a family dog when she was about 2. She had her own space away from the dog though to lessen the anixety.

Like I said I have moved out now. We have a dog but she is a lot calmer than the famly dog and cat and dog seem to get on well. I kept her inside for a few weeks wth the ktty litter tray and all seemed fine. I started to let her out and emptied the tray. Then I find she has been weeing in the dogs bed!! I threw the old bed out and bought a new one. I started to put her out at night. Yet she still wees in the poor dogs bed. Ive put the kitty litter tray back out and she still wees n the dogs bed!!! I put her out all morning and evenings but she stll comes back inside and uses the tray or dogs bed. I dont really want her to rely on the tray as i am not the best at keeping it clean and want her to go outside so i can get rid of the tray.

Any deas from anyone? Im at my wits end and my boyfrend and family are telling me to get rid of her. I love my cat to bits and want to fix the problem
