Robot lawnmower… Damn

Put in a sand pit somewhere you are ok with them shitting. Training domesticated cats is an undertaking that in my limited experience comes down to giving them an option they’d prefer over their current behavior. Trying to dissuade a feral cat from shitting where they please humanely seems like a loosing battle.

Place a box with sand near the area you want to protect. Move it further away a feet or so by day. In 10 days that cat will be shitting wherever you guided it to. Leave the box and or the sand. Done.

Low cost. Low effort. No animal cruelty. No dealing with neighbor. Effective.

Serious answer: I don’t think there’s much… I used to have a problem with cats pissing on my bicycle (which used to be parked outside) and the only thing that would keep them away was a bike alarm - at the expense of mine and my neighbors’ sleep. Covering the bike made no difference, they just pissed on the cover instead. The fix ended up being just parking my bike inside.

If you let the garden get a little bit overgrown, do they still come and drop their shit there?

Are you sure it’s cats?

Have you seen the cats pooping or just sniffing the poop?

Depends where you are, but foxes would be a more likely bet. Fox poop stinks too - really foul stuff. Cat poop generally is quite inocuos once it drys out, although a lawn mowing bot slicing it up would make sense for making it worse.

I have never heard of cats pooping in the middle of a lawn before. Normally they like private and safe spaces to poop as they’re vulnerable when pooping, and normally they’re fastidious about burying it where possible.

iF it really is cats, then maybe get a gravel section next to your lawn that they might prefer to go in? A litter box essentially.

My parents used to have this problem with dogs (our neighbors loved to let them shit everywhere but their own yard) and had a great amount of success with lining the perimeter of the property with moth balls.

@PlutoniumAcid i’m 64, i’ve lived in over a hundred different places, including rural and suburbs with lawns. literally never ever had this problem. not even when i owned cat! so it seems you’re cursed. you need to find the witch or wizard you offended and make amends.

i’m really amazed this would even happen, as cat prefer to bury their waste so they like places they can dig miles more than lawns. i wonder: did your u maybe see one cat, once, poop and now you think all poop is cat poop? because dogs are a lot more likely to be doing this regularly than cats.
