Product Review (submitted on April 30, 2011):

I purchased this device about 3 months ago, admittedly with some skepticism. For several years 3 neighborhood cats had been terrorizing and stalking the wild birds that I enjoy feeding; they were also eating the frogs that were living in my gardenpool. I am convinced it is working. I have not seen a cat in my yard and the bluebirds have been raising 4 nestlings, seemingly with no fear.The other birds have also been bathing and eating in peace. Thank you for this wonderful product.
