Neighborhood cats shit right in the middle of my lawn. It stinks and the robot lawn mover makes it even worse.
I do NOT like cats, and this is not helping.
What works to keep them from shitting on my lawn?
The votes have spoken. Some people are cat lovers; thanks for the great advice from the rest of you! I will not go out of my way to accommodate other people's pets that aren't welcome on my property. My first weapon of choice will be chili because it's simple and cheap. Other ideas have been noted.
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.
