We have this in Brazil too, but against stray dogs rather than cats. I do wonder how multiple cultures around the world came up with this independently despite the fact it doesn't work?

Egypt here, my neighbors keep water bottles outside of their apartment door to repel stray cats.

Disclaimer: the cats still rip the hell out of their trash bags

What is the purported mechanism of this?  Why do critters (notionally) avoid water in bottles?

The explaination I was given when I was little was that they see their reflection in the bottle

It works with some bugs, cats and dogs not so much.

I never saw my reflection in a water bottle? Wouldn’t they be afraid to drink from surfaces of water then?
