Negative Positive
Title: It does make a sound.
Review: When I received this I liked the size of the item. I do know it woke up a sleeping cat but nothing other than that. My dogs were not impacted by it at all. I saw one ear perk up so I know they heard it but just paid no attention to it. This would be a better item if you could fine tune the frequency to the animal you are trying to control. Shipping was quick and it was exactly what I ordered but useless to me for dog control.
