If your home smells like cats, you can eliminate it using the following methods:

Ventilation: Keep indoor air circulating by opening windows and closing screens to allow for ample airflow, which helps to eliminate odors naturally.
Use pet-specific air freshener: Spraying on pet-specific air freshener helps neutralize and eliminate odors in the air.
Clean up your cat's excrement promptly: Clean up the excrement in the litter box promptly, empty the excrement and wash the litter box to reduce the continuous spread of odor.
Use cat litter with good odor control: especially cat litter with strong odor-masking ability, which helps absorb and reduce the odor of cat excrement.
Bathe your cat regularly: If your cat has an odor, it may be because it hasn't been bathed in a long time. You can take your cat to a pet store for a bath to keep its skin and fur clean and dry.
Clean up cat hair and dirt: Remove cat hair and dirt scattered throughout the house daily to reduce odor.
Cleaning and disinfection: Spray the room with disinfectant such as 0.1% benzalkonium chloride or 2%-3% Lysol once a week, and spray with deodorant once a week.
Use deodorizing spray: After cleaning, you can use deodorizing spray to deodorize your home and effectively reduce odors.
