Here are some methods to remove cat urine odor:

1. Use a homemade cleaning solution: Pet owners can mix hydrogen peroxide, baking soda, dish soap and water in a spray bottle, then spray it evenly on the urine stain surface, wait for it to evaporate naturally, and finally place it in a ventilated place to dry.
2. Use white vinegar or lemon to remove: Note that the ratio of white vinegar to water should be 1:1. Then spray it on the area with urine stains and odor, let it sit for half an hour, and then clean it thoroughly.
In addition, pet owners can also solve this unnecessary trouble by cleaning the litter box in a timely manner and opening windows more often, because once urine has completely soaked into the fabric, it may be impossible to remove it completely.
