It's a common sight in Japan - water-filled plastic bottles in gardens, placed around plants. Apparently they deter cats from sitting on plants. Yes, sitting. And shitting on them, too.
Truth be told, I've never seen a cat hassling a plant - bottles or no bottles. But then maybe that's because I can't see any plants - because they're obscured by the bottles.
There could be a cat hiding behind these bottles.
Actually, take a walk in the 'hood and you'll likely see plenty of healthy-looking blooming flowers without bottles....
Flourishing flowers and not a bottle in sight.
However, sometimes it's not clear what the bottles are actually trying to protect....or just why they're there at all.....
An arrangement of bottles - but why?
Less of an arrangement, more of a scattering....
Whoever lives here must really despise cats.
Bottles of water protecting mud and weeds from cats. Maybe.
