Pestbye Battery Operated Electronic Ultrasonic Cat Repeller Repellent Scarer
The repeller comes with an infra-red (PIR) motion sensor which turns the device on when a warm body enters the controlled area. With the motion sensor, the theory is that cat learns to associate the noise with its own movement and is therefore much less likely to stop become desensitized to the noise.The device covers an 80 degree arc, to a distance of up to 23ft(7m), giving a total unobstructed working area of 184sq ft.Unlike most other repellers this allows you to cover a smaller area with the sensitivity dial. The repeller will give you the full 7m if the dial is fully round to the right; to decrease the distance turn to the left; this will help increase battery life as the repeller will cover the distance you want it to.If cats have a habit of feeding and fouling in your garden, it may take longer to achieve the desired effect.If you have a dog, it may be affected if it is allowed in the same part of the garden. The sound doesn't travel well through walls andfences, so it should not affect a dog in the house or a neighbour's dog.As with all methods involving animal behaviour, we can't guarantee effectiveness in every situation, however feedback from customers suggests that this device is effective in many situations.The device allows the changing of the frequency of the ultrasonic noise, potentially making it possible to target animals with hearing in different ultrasonic ranges, such as foxes and dogs.Dimensions: Height 10.5cm, Width 10.5cm, Depth 4.7cm.
