Why the ultrasonic cat removal (מרחיקחתוליםאולטראסוני) has no effect on humans?

The ultrasonic cat removal (מרחיק חתולים אולטראסוני) is the technique in which the devices or the techniques are used which make the cats go away by producing the noise pollution for the cats. Actually, the fact is that the frequency range of different species is different. The human beings have the ability to listen to the noises that lie within the range of 20 hertz to 20,000 hertz. Will the cats and dogs have the ability to listen to much more sensitive noises? The noises, which are not even heard by the humans, are smoothly detected by these animals. And make them go away.

It was important for the animals to have the sensitive noise range. This is because the predators approach the prey with the silent feet and if they don’t have this ability then they will kill them easily. This thing has been used by the inventors in a very clever way. They have made the machines and the devices that make a constant irritating noise that lies within the frequency range of these animals but not the human being’s frequency range. And in this way, the ultrasonic cat removal (מרחיקחתוליםאולטראסוני)does not cause any sort of inconveniences for the humans.
The cat removal without toxins (הרחקתחתוליםללארעלים)is made especially for the cats. It makes the hindrances between their communications. They not only make it difficult for the cats to communicate with each other but also make it difficult for the cast to remember their tracks. In this way, they make the cats remember that a certain place is not the place to go and they move to anywhere else. The devices work the whole day and night making this thing sure that they don’t enter the house no matter whether one is present in the house or not, or the person is sleeping or not.
