Is the cat sensitive to ultrasound?

Some people use ultrasound devices for keep cats away neighbors who cause damage to their garden. Scratching, droppings in flowerbeds, flower beds and the vegetable garden, attacks by laying hens, urine markings on the threshold of the front door are among the many reasons that lead to seek an effective solution to dissuade a kitty from breaking in. in a property. Among what motivates these people, we also note the unbearable meowing especially at night time. Are these devices really effective? Before answering this question, let’s first discuss the sensitivity of cats to ultrasound and let’s also see if these waves are likely to represent any danger for our friends the cats.

Perception of ultrasound by cats

We know that the dog perceives ultrasound, but we often ignore that the cat also hears waves that are not accessible to the human ear. More precisely, his reception spectrum is located between 60,000 and 65,000 Hz. This corresponds to as many oscillations (or cycles) per second. This is considerable, since our ear perceives sounds whose frequency is limited to 20,000 Hz. Note that the higher this frequency, the higher the sounds.

With its overdeveloped hearing, the cat therefore hears thunder, for example, well before its master. It has a very large number of neurons in the auditory area. And thanks to its ears whose mobility is important because of the 27 muscles that each has, the kitty can easily know where the sounds he hears come from since his ears rotate through an angle of 180 °. In this way, he orients his auditory pavilions as he pleases.

At the level of the middle ear, the received frequencies are modulated by muscles. The transmission of sound can also be reduced in order to limit damage to the inner ear, and more particularly to the sensory organs. There is no doubt, the cat is a fabulous hunter perfectly equipped to locate its prey day and night since the vibrations of the air allow it to monitor its environment continuously.

Ultrasonic devices to scare away cats

We now know that cats are generally extremely sensitive to ultrasound. Based on this observation, manufacturers have designed ultrasonic deterrents that can be classified among the natural cat repellents. In order to reassure lovers of small felines, these specific devices do not represent no danger for pets. They only generate discomfort which causes the little feline to flee.

The harmfulness of ultrasound devices is only real if their frequency level is very high and they are used for a long time. But these are devices reserved for use in the industrial field. They are therefore incomparable with anti-cat ultrasonic solutions which, remember, are perfectly painless.

You should know that the maximum ultrasound frequency is ten million Hertz (Hz). There are even frequencies above this limit, but we speak of hypersonorous waves or hypersons. Ultrasonic devices marketed for the general public and which can be used at home or in the garden (ultrasonic repellents to plug in, battery or solar special cat in particular) do not emit such a frequency. So they are perfectly suited to keep a kitty away from the garden without ever hurting him.
