Sonic Repellents for Cats

Detect and deter cats from lawns, flower-beds and bird feeders. Ultrasonic cat repellents work by emitting a very loud noise at frequencies inaudible to humans – but audible and important to cats. An ultrasonic cat repellent device will activate when it detects movement and will then activate by projecting a very high-pitched frequency. Ultrasonic Cat repellant devices have a PIR sensitivity adjuster and a frequency adjuster so it can be aimed at different sizes of animal. New research for the RSPB has shown they can reduce cat visits into gardens by a third.
