Many homes have cats. The owners love their furry pets very much and allow them a lot, but there are places where they are forbidden to enter. It is difficult to explain to the animal that a dining table or window sill, laden with flower pots, is not a place for walking.
Kittens are especially curious, who strive to explore everything around. It is very difficult to wean stubborn pets from visiting prohibited places. It is much easier to purchase an ultrasonic cat repeller.
What is the device for?
The human ear does not pick up ultrasonic pulses, but cats can hear them perfectly. This very high and subtlest sound is unpleasant for animals, they try to leave the place where this device is installed faster. The device is a psychological “weapon” against pets, it does not affect the vital activity of any organism. Due to this, it can be used without restrictions.
Ultrasound does not affect deaf cats, and may also not affect the animal in a state of rest and relaxation. Further about the most popular ultrasonic cat repellers, whose reviews are the best.
Weitech WK0052
The ultrasonic cat repeller is equipped with a motion sensor with a viewing angle of 90 ° and a range of 15 meters. When any movement appears in this radius, the ultrasonic speaker is activated. It generates signals with a volume of at least 110 decibels, which is comparable to the baby’s strongest scream. The volume of the signal greatly scares the four-legged, so they try to leave the danger zone.
If after such a series there are no more movements in the area of the motion sensor, the device will turn off and wait for the next “victim”. The range of the ultrasonic waves of the device is at least 20 meters. The model has advantages that distinguish it from competitors:
- Universal food. This model can be used not only in the same place. The device can be rearranged if necessary. For example, in the spring for a gardener, the device will be a salvation from animals that tear the bark of trees with their claws, and in summer it can be placed next to a place for children to rest.
- High efficiency. The device expels any animals from the territory. No need to purchase various devices for different purposes. The device has 7 operating modes, the first involves a minimum amount of ultrasound, which scares only cats. Accordingly, the latest program includes ultrasound at full power, which also eliminates dogs, foxes, hares and pigeons.
- Moisture and dust protection. The device is not afraid of exposure to water and dust. This concerns the fact that it will withstand rain of any intensity, however, if it is completely immersed in water, the repeller will not be able to fully perform its functions.

The device will not allow dogs, cats and dogs to approach a distance of 200 square meters. This model of street ultrasonic cat repeller can be used in the following places:
- At checkpoints. The device prevents the entry of animals into the closed zone: internal warehouses, food processing enterprises.
- In the area around the house. The device protects people from contact with aggressive and stray dogs, stray cats, which are often carriers of various infectious diseases.
- In the area of schools, kindergartens and hospitals. It is especially important here to protect children from homeless animals, because not every child understands that a pleasant-looking cat can cause significant damage to her health.
The ultrasonic cat repeller is mounted on a wall, pole or on any other support, its body is protected from the effects of rainfall. The power of the device is only 1.5 watts, this allows you to use it around the clock.

Two speakers emit ultrasound with an acoustic pressure level of up to 120 decibels. This can be compared with the sound volume at a rock concert or during a severe thunderstorm. Acoustic signals from the device act on animals within a radius of 20 meters.
The frequency of ultrasound changes so that animals are not used to it. The algorithm for this adjustment sounds completely unpredictable for animals. The device has two speakers. They are located at a distance from each other and at a certain angle. This ensures the formation of a uniform ultrasonic field throughout the space in range.
A motion sensor picks up any activity. When it detects movement, the generation of a series of repulsive signals will begin at full volume, which will not stop until there are no movements in the radius.
The ultrasonic cat repeller is easy to install, the brackets rotate freely. Due to this, it can be installed both vertically and horizontally. It can also be mounted on an inclined surface: door slopes or cornices of the facade of the building. Lead the device 120 grams, there is no need for strong fasteners.

The universal battery-powered ultrasonic cat repeller also acts on other animals: dogs, rodents, ferrets. Powered by four batteries, thanks to this it can be installed not only indoors, but also in the garden, on lawns, next to flower beds. The device does not affect people, does not pollute the environment.
Among the advantages of the repeller, one can distinguish the presence of a light panel on the front of the case, which can flicker. This greatly enhances the restraining effect in a dark room. Low price and battery life is also an advantage of the model.
The motion sensor detects activity, the device only works as needed. This conserves battery power significantly. The device is suitable for urban apartments, as it has a small radius of action.
DIY Ultrasonic Cat Repeller
Those pet owners who are even a little familiar with electronics will be able to make the simplest device with their own hands according to the scheme.
To do this, you need variable resistors, a piezo emitter, transistors, diodes, a toggle switch, and a capacitor. Resistors limit the current strength, reduce the magnitude of the operating voltage, and allow you to adjust the frequency of the emitted ultrasound waves.
A piezo emitter is needed to reproduce ultrasound. Resistors and capacitor form a working frequency circuit. Diodes are necessary to protect against incorrect power supply connection. Using the toggle switch, the device turns on and off. For food, you need to purchase several finger batteries.
According to reviews, ultrasonic cat repellers do their job well, reliably guarding the territory that the owners want to protect from the tricks of their curious pets.
