The cats distributor is functioning properly and we now have our peace of cats. The cats do now all a big circle around our flower bed. However, I feel that it really did not hear white cats. Because recently sat a white cat in front of the device and there she was interested absolutely not that this device are these horrible sound. I even hear the beeping not, but we have a stone distributor are right next to our front door. Now it is so that the children hear this beep and perceive it as very unpleasant when they ring with us. Whether that is now either positive or negative, each self is left :-) I would buy the parts definitely immediately. I am very pleased.
