I suspect that if a sonic gizmo went off in my ear, I'd probably drop a load too!

There are some wildlife parks or zoos that sell lion poop to ward off unfriendly animals from floor spaces, gardens, that sort of thing. Which is fine if you like the smell of lion poop. Of course, in real country, you may just end up with a randy lion sniffing round!

Citrus smells are usually unwelcome to feline animals, they don't like them too much, so try some orange cleaner, or fruit peel around the holes.
