Follow these steps, and your carpet will be stain-free and smell fresh: 1. Blot the area with cotton or paper towels to absorb the urine. 2. Rinse the spot your cat peed on and vacuum it. 3. Put some Enzyme Cleaner and soak the stained spot. 4. Allow it to sit for a bit before blotting it again with a clean cloth. 5. Stop your cat from going to that area again. 6. Reapply the Enzyme Cleaner if you need to, and repeat the process once more.
