THE PROBLEM WITH PET URINE Pet urine has three components that ordinary cleaners can't treat: 1. Urea - a sticky waste protein product 2. Uric acid crystals - gives urine its terrible odour 3. Creatinine - proteins that cause bacteria to grow Pets (specially cats) re-mark when they detect the odour of their old stains, even when humans cannot smell anything at all.
