Many houses 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 an animal that a dining table or a window sill full of flower pots is not a place to walk around.
Kittens are especially curious, they strive to explore everything around. It is very difficult to wean stubborn pets from visiting forbidden places. It is much easier to purchase an ultrasonic cat repeller.
What is the device for
The human ear can't pick up ultrasonic pulses, but cats can hear them perfectly. This very high and subtlest sound is unpleasant for animals, they try to quickly leave the place where this device is installed. The device is a psychological "weapon" against pets, it does not affectlife of any organism. Thanks to this, it can be used without restrictions.
Ultrasound does not work on deaf cats, and may not work on an animal at rest and relaxation. Read more about the most popular ultrasonic cat repellers, which have the best reviews.
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 there is any movement within this radius, the ultrasonic speaker is activated. It generates signals with a volume of at least 110 decibels, this is comparable to the strongest cry of a baby. The volume of the signal greatly frightens the four-legged ones, so they try to leave the danger zone.
If after such a series there are no more movements in the motion sensor zone, the device will turn off and wait for the next "victim". The range of 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 become a rescue from animals that tear the bark of trees with their claws, and in the summer it can be placed next to a place for children to relax.
- High efficiency. The device expels any animals from the territory. No need to purchase different devices for different purposes. The device has 7 modes of operation, the first involves a minimum volume of ultrasound, which scares only cats. Accordingly, the last program turns on the ultrasound at full power, which also eliminates dogs, foxes, hares and pigeons.
- Waterproof and dustproof. The device is not afraid of water and dust. This concerns the fact that it will withstand rain of any intensity, however, under conditions of complete immersion in water, the repeller will not be able to fully perform its functions.

The device will prevent dogs, cats and dogs from approaching up to 200 square meters. This model of outdoor ultrasonic cat repeller can be used in the following places:
- At checkpoints. The device prevents animals from entering the closed area: indoor warehouses, food processing plants.
- 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. Here, it is especially important to protect children from homeless animals, because not every child understands that a nice-looking cat can cause significant damage to their he alth.
The ultrasonic cat repeller is mounted on a wall, pole or any other support, its body is protected from precipitation. The power of the device is only 1.5 W, which allows you to use it around the clock.

Two speakers produce ultrasound with a levelacoustic pressure up to 120 decibels. This can be compared to the volume of sound 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 the ultrasound changes so that the animals don't get used to it. The algorithm of such a restructuring 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 over the entire space within the radius of action.
Motion sensor picks up any activity. When it detects movement, it will generate a series of knockback signals at full volume, which will not stop until there is no movement in the radius.
The Ultrasonic Cat Repeller is easy to mount, the arms rotate freely. Thanks 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. To carry the device 120 grams, no need for strong fasteners.

Universal battery operated ultrasonic cat repeller also works 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 on the frontparts of the lightbar housing that may flicker. This greatly enhances the deterrent effect in a dark room. The low price and autonomy of work is also an advantage of the model.
Motion sensor detects activity, the device works only as needed. This saves a lot of battery life. The device is suitable for urban apartments, as it has a short range.
Do-it-yourself ultrasonic cat repeller
Those pet owners who are at least 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-value resistors, a piezo emitter, transistors, diodes, a toggle switch, a capacitor. Resistors limit the current, reduce the operating voltage, and allow you to adjust the frequency of the emitted ultrasonic waves.
A piezo emitter is needed to reproduce ultrasound. Resistors and a capacitor form a working frequency circuit. Diodes are needed to protect against incorrect connection of the power supply. Using the toggle switch, the device turns on and off. For power, you need to purchase several AA batteries.
According to reviews, ultrasonic cat repellers do an excellent job of their functions, reliably protecting the territory that the owners want to protect from the antics of their curious pets.
