The cats are likely not the ones crapping on the grass because they need to bury their scat.
We’ve got a number of felines who were using my flower bed for a litter box and I solved the problem easily.
Included some marigolds, which cats dislike.
And put a couple of boxes of clear plastic forks to good use in the clear spots in the flower bed.
Take the fork, slide the handle into the dirt so that the tines stick up. And use a lot of them.
You won’t see the forks, especially after your plants are established. And after the kitties get their prats poked, they get the idea to jog on.
I haven’t had a problem since I started doing that.
Good advice. Thanks.
I had the problem once of neighborhood cats crapping in a flowerbed just outside my front door. I got a lot of ground cayenne pepper and applied it liberally to the area, a few ounces at a time. After a while, the cats learned to go somewhere else.
In this case, the guy should live-trap every cat he can and either take them to the pound or relocate them far away. We have five cats and they all stay indoors. I don’t shoot the few feral cats around here (no need, coyotes get them before long), but I do chase them out of our yard.
