Hahaha, actually it might be entertaining to put about 1,000 cats in there that haven't been declawed, instead of dogs, and then unleash the water cannons 😱
Pretty cool..... Some commercial buildings have a burglar alarm system that sounds like that. If you get inside the building when the system is turned on, it will turn on and drive you nuts. I once set one off one afternoon in a bowling alley that was closed but I had the door keys to get in and read their gas & electric meters. System was supposed to be off...... except somebody forgot to shut it off. There's about a 30 second delay from when you trip the alarm until the noise starts. Enough time that I was well into the building when it started...... Damn; that thing was LOUD.
