The ASPCA lists motion-activated sprinklers, ultrasonic devices and natural deterrents as good ways to get rid of stray cats in the yard. The goal of these methods is to make the yard as unappealing to the stray cats as possible.Continue Reading
Most cats do not like to get wet, so using a motion-activated sprinkler discourages them from coming into the yard. The sprinkler activates whenever cats come within range of its sensor. The sprinkler then shoots a burst of water that is strong enough to scare them away without injuring the animals. It typically takes a few days for this method to drive stray cats away completely. Other motion-activated devices emit an ultrasonic sound to deter stray cats. Movement triggers the motion-activated ultrasonic device, which emits a high-frequency sound. The sound is undetectable by people, but cats can't stand it. The device doesn't have the same instant startling effect as water, but it does drive cats away from the area of the sound.
Natural deterrents require removing or placing out of reach things that attract cats. Some strays enjoy using flower beds to lounge in or relieve themselves. Removing the flower beds completely, placing chicken wire around them at ground level or placing chicken wire just under the surface of the dirt keeps strays at bay. You can also make the ground uncomfortable for stray cats to walk on or dig in by placing plastic under the surface of the dirt or laying down prickly pine cones.Learn more about Furry Pests
