Motion-Activated Ultrasonic Cat Deterrent for Gardens, Yards & Outdoor Areas
Incl VAT, Free Shipping & Easy Returns.
Details
Cats can quickly turn gardens, lawns, flower beds, and vegetable patches into unwanted territory. This motion-activated ultrasonic deterrent is designed to discourage cats from entering protected outdoor spaces without using chemicals, traps, or harmful methods.
Designed Specifically for Cats
Unlike generic animal deterrents, this device operates within the hearing range of cats, using ultrasonic frequencies between 16 and 60 kHz. Combined with a PIR motion sensor, the device only activates when movement is detected, helping conserve battery life while providing targeted protection.
Motion Detection with Automatic Activation
The integrated PIR sensor detects movement within a range of up to 30 feet and a detection angle of 110°. When a cat enters the protected area, the device automatically emits ultrasonic frequencies designed to create an uncomfortable environment that encourages the animal to leave.
A Humane Alternative to Chemicals and Traps
This deterrent is designed to repel cats without causing physical harm. No poisons, traps, sprays, or toxic substances are required, making it a safer solution for gardens, homes, and outdoor spaces.
Built for Outdoor Use
The weather-resistant housing features an IPX4 waterproof rating, allowing the device to remain outdoors during rain and changing weather conditions. Its durable ABS construction is designed for long-term outdoor use.
Long Battery Life with Low Energy Consumption
Powered by three AA batteries, the device can operate for approximately six months under normal usage conditions. The motion-activated system helps minimize unnecessary power consumption.

How It Works
- The PIR sensor detects movement.
- The device activates ultrasonic frequencies within the cat hearing range.
- The animal experiences an uncomfortable acoustic environment.
- Repeated exposure encourages cats to avoid the protected area.
Why Cats React to Ultrasound
Cats can hear frequencies far beyond the human hearing range, detecting sounds up to approximately 60 kHz. By operating within this sensitivity range, the device creates a deterrent effect while remaining largely inaudible to most adults.

Frequently Asked Questions
Is this safe for cats?
Yes. The device is designed to deter cats without causing injury or physical harm. It simply creates an environment they generally prefer to avoid.
Can humans hear the sound?
Most adults cannot hear the ultrasonic frequencies emitted by the device. However, some younger individuals or people with sensitive hearing may occasionally notice a faint high-pitched sound during activation.
Can it affect other animals?
Although designed for cats, some animals sensitive to similar ultrasonic frequencies, such as raccoons, foxes, badgers, or skunks, may also avoid the protected area.
How long do the batteries last?
With normal use, three AA batteries typically provide up to six months of operation.
Does it work continuously?
No. The device activates only when movement is detected, helping extend battery life and reducing unnecessary operation.
