Found something unusual in our garage today. It looks like a straw (plastic twine) with a plastic cup tied to it. I'm curious if anyone has seen something like this before or knows if there's any specific meaning behind it. Could it be a prank, or is there some other motive? It’s just puzzling me, and I’d appreciate any insight!

PS: We have two dogs that roam around our property
