Advanced Ultrasonic Cat Scarer Repeller

Sends out a very loud noise at a frequency that cats can hear but is too high for most humans to hear. This is annoying and frightening to the cats but does not affect birds. Also effective for dogs and foxes.

The Advanced Cat Repeller incorporates a sophisticated PIR (Passive Infra Red) motion sensor which turns the device on when a warm body enters the controlled area. This has an important purpose other than saving battery life: researchers have found that cats can become desensitised to the noise if they realise that random sounds are not associated directly with their presence in the controlled area. With the motion sensor, the cat learns to associate the noise with its own movement, and is much less likely to stop being afraid of the noise.

What area does it cover?
It covers a 120 degree arc, to a distance of up to 52.5ft (16m), giving a total unobstructed working area of (188 Square Metres).

How quickly will it work?
If the cats have a habit of feeding and fouling in your garden, it can take 14-28 days to deliver the full deterrent effect. 'Occasional' visitors will usually be stopped within 7 days. Of course, as with all methods involving animal behaviour, we can't guarantee effectiveness in every situation, however, our own experience and the feedback we get from customers suggests that this device is effective in almost all situations. If you have a dog, it may affect the dog if it's allowed in the same part of the garden. The sound doesn't travel well through walls and fences, so it won't affect a dog in the house, or a neighbour's dog.

Requires 2 x 9 Volt batteries (not included). Battery life depends on how many times the device is activated, but they typically last 3-4 months assuming 10 activations per day.

Coverage area is approximately 188sq metres in a 120° fan shaped arc.
