When keeping a cat at home, you can choose the following methods to kill mosquitoes:
1. Use physical methods to prevent mosquitoes, such as window screens, mosquito nets, and electric mosquito swatters. These methods will not harm your cat and are very effective. Window screens, in particular, can effectively prevent mosquitoes from entering the room.
2. Natural mosquito repellent products, such as natural peppermint powder, are safe for cats and have a certain mosquito-repelling effect. However, when using them, be careful to place them out of the cat's reach to prevent accidental ingestion.

3: Catnip extract is said to be effective at repelling mosquitoes, but it still needs to be placed in a place where cats cannot directly access it.
4. Short-term use of mosquito lamps has little impact on cats, but long-term use may have adverse effects on their skin, so caution should be exercised when using them.
5. Keep your home environment clean and reduce stagnant water to prevent mosquito breeding.
