Electronic Barking Secure Watch Dog - Ultrasonic Barking Dog Alarm for Home Security - Perfect for Deterring Intruders & Protecting Property

So, first, overall, huge approval of this mechanism. I have a naughty kitty I couldn't stop from going in a corner of the house, in my gym! Tried everything! btw, those hormones that are sold that profess to stop cats from fighting and tinkling? huge waste of money.I got the notion to get one of these barking motion detectors. It instantly stopped the naughty behavior!An oddity, the smallest cat, it doesn't detect. Fortunately, she is not the problem.I have another cat, he's the most curious, impish, and intelligent; he teases the "dog", which can be annoying, but I'd rather have that nuisance than the odiferous nuisance.The offending kitty is also not large. She can access her hiding place nearby without detection, so that's fine.The barking operates so that the first detection elicits one bark. If the detection persists, it quickly lets out a couple barks. If intrusion continues, it really lets loose, which is enough to chase not only any cat, but ME.Lastly, this machine comes with a great remote. So, I can arm and disarm the machine without having to endure the noisy barking every time I want to use my gym. It also has a panic button so I can scare the cats without them knowing I'M the one making it happen.So, maybe not helpful for anyone looking to scare people, but may be the salvation of a naughty kitty whose parents are at wits end. :)ps. I wish there were some way to set this up outdoors around the garden to keep out the squirrels and bunnies without having to put up a cage. Manufacturers? if you are reading this? :)
