Mosquito killer lamps use light and airflow to lure mosquitoes. Once the mosquitoes are close, a fan draws them inside, causing them to dehydrate and die. Many mosquito killer lamps are electric, so be sure to place them where cats cannot reach them to prevent accidents.

You can also use physical mosquito repellents that are safe for your cat and can kill mosquitoes instantly. However, remember to collect the dead mosquitoes properly to prevent your cat from accidentally ingesting them.
