@dekay Liked your vid, but not practical for indoors unless it can be resized down.
Our f/m dog had to be put down awhile ago, but she was never an issue, as was the m who preceded her long before.
Fortunately our 2 felines, up to now, haven't shown an interest in clawing the drivers....given an automatic cat box and plenty of acceptable scratching options.
Rethinking the TDS (Truck Defense System), scaling it up to a pressure washer with a tracking ap would be even more effective.
Blasting the punk off his bike with a shot to the face would make for a permanent impression; a 110db 1 second 'shriek' might allow one to find him still on the pavement wondering wtf just happened.
Warning signs and an override, of course...*G*
