You might look into investing in some Nature’s Miracle. It’s an enzymatic cleaner that breaks down urine. Definitely saved us when we had to keep our friendly stray inside after we had him neutered. His pees were the absolute WORST, all over the baseboards and laminate floors, totally burned your eyes when you walked into that room. The only one that could tell there was ever cat pee in that room in our house was my cat, and only because he sniffed everything out when I first brought him home as a kitten. We sprayed the spot again, and his nose never led him back, lol.
