This cat comes distributor so far for 3 weeks in our garden are used. Constantly running through neighboring cats, destroyed nests and dead bird boy and cat shops smelly sandbox areas that were not perfectly covered for so long fueled our anger that I finally had to try to drive the animals. The key for me was an indication that the votes Video- tones for people rarely heard there are nerve frightening devices, the more self vertreiben- from the garden and especially the birds do not mind a. Unfortunately, our land will need at least 2 units. Have a good piece so stuck for 2 weeks in the "green zone" under a potato Rose on the floor, chose the angle of the field of usual surreptitious route of cats and saw there actually no more. Outside the angle already. I changed this, we noticed also in this way no more animals up to the birds that seem to really not bothered to feel. For a week of fairly large sandy area for the kids is on the other side of the property guarded by the distributor, not abgedeckt- how annoying job that is always, and alas, it was sometimes forgotten ...- still übergeharkt for ease of inspection and to left open the next use. Not a single bunch more! Otherwise you could wait a day to the candidate, who sought an open patch of sand or earth and further underlined by the flowerbeds. There, too, draw the blackbirds, chickadees and Co continue across the lawn. Clear I will continue to watch before ordering the second device for 2 weeks whether there really is no way habituation effect for the cats. Toll way, is also the rather generous extension cord. A faint clicking noise signaled me saying that I'll just registered by the device in the enclosed area. But the úton is actually imperceptible to humans. Irrigation did not disturb the device so far. No full credit there, because I would like to see an even greater detection angle. One may well not have everything. ALSO partially almost twice as expensive equipment need not be, when it comes to the action effect (without comparing the above-mentioned angle).
