Cat urine has earned a reputation for being one of the most formidable of all pet odors. It not only smells terrible, but has a persistent odor that must be removed entirely. A cat's urine has that super strong odor because it is protein based. When cat urine dries on the carpet it forms crystals and those crystals are the source of the strong odor. In most cases when cats cannot control their urinating, it is usually a sign of feline diabetes from too much sugar in their diet [source: Cornell]. You can take a sample of your cat's urine and send it in for testing. The laboratory will test the urine for protein, glucose and urine pH, along with a variety of other tests. The results will determine if there is a problem [source: Hillestad]. In the meantime, let's get rid of the smell.

Here's what you need:

  • Towel
  • Brush
  • Warm water
  • Pet enzyme/baking soda

Here's what to do:

  1. Remove as much of the urine as possible. You can either try blotting it with a dry towel or soaking it up in a rag with warm water.
  2. Pour a pet enzyme product on the area and let it soak in for a while. Blot it with a dry cloth [source: Heloise]. In the event that you don't have a pet enzyme product, you can substitute baking soda. Simply pour a liberal amount of baking soda over the area. Let it stand for a quarter of an hour and then vacuum it up [source: Arm & Hammer].
