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.
A robot lawnmower costs between $700 and $3000. A fence starts at around $5000 and can get into the $30,000s easily. It's almost like you have no idea what you are talking about. Additionally, if the person needs a lawnmower then having a robot one isn't a much bigger expense.
Finally, to really highlight how stupid your responses are, you do realize that cats can jump fences, right? A normal house cat can jump 6ft quite easily, and outdoor stray cats jump onto our 8ft tall privacy wall all the time.
