Here are some ways to eliminate the smell of cat urine:

1. Clean with deodorant
If a cat urinates on the carpet, it can easily emit an unpleasant odor. Therefore, the owner should clean it up promptly and gently apply some deodorizer to the spot where the cat urinated, then wash it clean to remove the smell.
2. Apply a few drops of floral water to the water for washing.
To remove the smell of cat urine from your home, simply prepare a basin of water, add some fabric softener or floral water, and then use it to mop the floor. This will effectively remove the urine odor.
3. Spray with citric acid
Spraying citric acid on the areas where your cat has urinated is the most effective method. It's also convenient and easy to use, and it's very effective at removing urine odor. However, owners should never spray citric acid directly on their cats, as cats are extremely afraid of it.
