A neighbour on my street has got into the habit of carrying their litter tray onto the public path and pouring the litter into the drain. It's one of those open drains with the grating across it iyswim.
Not only the fact that they spill it everywhere and make no attempt to clear it up I'm worried that they are gong to block the drains. We've had regular problems in the past with drains being blocked and having to call out the water service, who always confirm it's from people putting wipes and nappies down there!
AIBU to say something? Or is this actually a normal thing to do and, as a non cat owner, I just don't realise it?
