CATWatch Ultrasonic Cat Deterrent is the only cat deterrent that is endorsed by the RSPB. The deterrent works by emitting an ultrasonic alarm, which is triggered by the cat's movement and body heat. The frequency emitted will not have an effect on humans or other garden wildlife such as hedgehogs. The CATWatch can take up to four weeks to become effective, especially when placed in a cat's established territory. The CATWatch has a detection area of 12 metres in front of the sensor and the ultrasonic sound is effective up to 16 metres away. The CATWatch is powered by a 9V battery (not included) (duracell batteries are recommended) but can also be connected to the mains using a 12V mains adapter which is available separately. The device has a spike so that it can be pushed into the ground. Although the device deters cats it does not cause them any harm.
