What will deter fisher cats?

To deter fisher cats, consider using motion-activated lights or noise devices, as these can scare them away. Fencing that is at least six feet tall and buried a foot underground can also help keep them out of your yard. Additionally, removing food sources, such as pet food and trash, and keeping small pets indoors can minimize attractants. Planting dense shrubs or using repellents may also help create an unwelcoming environment for these animals.
