My heart goes out to you. So sorry. My daughter moved out 2 years ago at 28 yrs old. She had 2 cats that would pee any where. We demand that she keep them in her room and not roam our home. They would escape and I had to throw out several tubs of fabric. I used every thing but the smell never came out. Still finding little gifts they left. i asked the vet and he said nothing stops some cats from doing this. We are sealing the floor from all the cat stuff left in that room.
