If your home has a strong cat odor, you can try the following methods to reduce or eliminate the smell:

Ventilation: Opening windows to allow air circulation helps reduce indoor odors. However, please note that when ventilating, keep your cat in another room to prevent them from climbing onto the windowsill out of curiosity and falling.
Clean up promptly:
Clean up your cat's waste: Clean the litter box regularly to ensure waste is removed promptly and to prevent odors from lingering. For multi-cat households, it is recommended to clean the litter box once or twice daily and change the litter at least once a week.
Clean your cat's fur and dander: Regularly brush your cat's fur to remove loose fur, dander, and dirt, reducing odor.
Use deodorizing products:
Cat litter: Choose cat litter with good odor control, especially cat litter with strong odor-masking ability, such as bentonite cat litter with larger granules.
Antibacterial agent: Adding some antibacterial agent to the litter box helps kill bacteria in cat excrement and reduce odor.
Pet-specific air freshener: Spray pet-specific air freshener in your home to help remove odors.
Fragrance: Use a fragrance that is harmless to cats to help mask odors. However, please be careful to avoid using fragrances that are harmful to cats.
