How can I effectively remove the smell of cat pee from a rug?

To effectively remove the smell of cat pee from a rug, start by blotting up as much of the urine as possible with paper towels. Then, mix a solution of equal parts water and white vinegar and pour it over the affected area. Let it sit for about 10-15 minutes before blotting it up with more paper towels. Finally, sprinkle baking soda over the area and let it sit for a few hours before vacuuming it up. Repeat these steps if necessary until the smell is gone.
