In the past, teaching them to stay out of or away from areas was next to impossible. But now, thanks to CatScram, training a cat to avoid areas has become possible. Catscram makes any area off limits to cats, even when you are sound asleep or nobody is home. It utilizes a passive infrared motion detector to sense when the cat nears the 90-degree protected area. The unit then emits a series of strong pulsating ultrasonic waves, which are harmless, are only heard by cats and are inaudible to humans.
Cats find the sound so irritating that areas which are guarded soon avoided altogether.
Because it uses sound waves, no bulky self-correcting collar needs to be worn by the cat. It uses minimal power and indicates when the 9-volt battery is low. CatScram keeps cats away from designated areas to protect your belongings and your cat. It can keep them away from poisonous plants, hot stovetops, balconies and dangerous machinery. Passive infrared motion detector features an ultrasonic speaker which emits harmless high-frequency sound that deters cats, yet is inaudible to humans.
