I don’t know about you but I love cats in my backyard. They can cause a lot of mess though, especially if you have plenty of feral cats and other animals roaming your yard. This 40ft Solar Solar Ultrasonic Cat Repellent can help. It uses PIR detection to distinguish between animals around your property.
The unit has multiple modes, including a mole repellent mode with LED light ideal for night use. It has a working range of 120-degrees with 40ft radius. It is IP45 rated. It runs on a 2200mAh battery for up to 3 weeks.
