Bottles Of Water On The Doorstep

[Bert45]

In Spain and Italy I have seen people put squash or soft drinks bottles, filled with water, on their doorsteps. I have been told that this is to deter cats or dogs, or both, from fouling the pavement near the door. Does anybody know if this has been scientifically proven to work?

I suspect that someone is pulling your leg.

Doubt if you would need a scientist to prove it .. the proof would be on the sole of your flip flop !

I think its to do with distorted reflections on the bottles, somehow it freaks out cats / dogs, and they move on.

I could see the thing, mentioned in Snopes, of leaving open vessels of diluted bleach around would deter dogs because of the smell but it sounds pretty unsafe to me. I honestly don't believe leaving sealed bottles of water around will make any difference whatsoever.
