However, there are places where the use of a cat deterrent is necessary, especially when it comes to unfamiliar animals that need to be kept away from your surroundings. With this cat deterrent device, you can drive away cats in an environmentally friendly and non-violent manner. The ultrasonic sound of 55 kHz, which is inaudible to humans and dogs, helps make your garden or terrace unattractive to unwanted cats. Sounds in this frequency range are perceived as very disturbing, creating a deterrent effect. As a result, the animals will avoid the treated area and prefer to seek out other environments. This cat deterrent is specifically designed for dog owners, as a sound of 55 kHz is not audible to dogs. Thus, this cat repellent only deters cats and goes unnoticed by dogs. An infrared motion sensor detects whether a cat is nearby, and the ultrasonic sound is activated. The emitted sound is harmless to both humans and animals, making it an ideal cat deterrent for gardens, doorways, and living spaces.
