We've got a cat and for the past month someone keeps delivering cat poo in a bag to either our front door or the back garden. This has happened 4 times already. I get this must be annoying, especially if you don't have cats... but is posting the cat poo back really okay?! Also, how does that person know the poo they bagged belongs to our cat? There must be tons of cats roaming in the area. I'm at a loss at what to do and have 3 young dc, so finding bagged up poo around our property is not on. My aibu is what would you do, if a cat frequently visited your garden? Would you take back the offending poo?! If the person who did it was genuinely upset, I'd buy cat deterrent supplies and do what I can. But honestly, he's a cat, I can't police her everyday.
