Unfortunately, I have learned that none of the cats from the area is "quenched" by the device. On the contrary, sometimes I even had the feeling that they were attracted by the sounds. Have the unit also tried directly with my parents at their house cat and also this was not impressed in the least of it.
Sitting half a meter in front of the Animal Away and licks his paws!
Conclusion: for scaring off cats anyway unfit. Have already returned the device!
