How to Use an Onion to Deodorize a Cat Litter Box

Use an onion to reduce the odor from a cat litter box? This doesn't make sense at first, but there's some valid science behind it. The same chemicals that make you cry when you cut the onion act as a germ killer to reduce the bacteria that produce that cat box odor.

Things You'll Need

  • Cat litter box
  • Onion
  • Small bowl to place the onion halves in
  • Baking soda (optional)

Instructions

    • 1

      Get an onion. It doesn't matter what color the onion is, so just buy the cheapest you can find.

    • 2

      Cut the onion in half across its equator. This exposes the maximum cut surface. You can also cut the halves in half.

    • 3

      Place the cut onion in an open bowl or box that is close to the litter box but out of sight.

    • 4

      You can also place the onion pieces in the litter box at first and then move them to the bowl.

    • 5

      Replace the onion as it deteriorates.
