Only IT WORKS I have a cat and she urinated on the floor since we brought her from the shelter 5 years ago. She only peed on the tile floor (phew) but literally everywhere on the tile floor. I watched heaps of professonals' videos regarding cats' urination. What I did: I tried all urine enzyme cleaners sold in Australia (Literally all). Used black light and removed all stains. Placed 5 litter trays for a cat. Used the most expensive litter clay (very soft). Let my cat have urine test and kidney ultrasound - all normal. Cleaned the litter clay everyday and changed the whole clay to new clay once a month. Feliway diffuser - 4 spots. But she still urinated on the floor. I nearly gave up cleaning pee honestly. I found this detergent and thought that it will be the last. I tried.....and she doesn't pee on the same spot anymore! Only Petlab works on my cat's bad habit. I will purchase more and please don't give up this business.....i cannot find the better item.
