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.
depending on your jurisdiction, but especially in rural and farm areas you may be permitted to cull feral animals on your property.
In ecologically sensitive areas, (basically Islands, the Americas, Australia) cats are a invasive species, and put local small animal species in extreme danger. There may be a government program to assist in your effort. i.e. Australia's Cat Free Kangroo Island initiative https://conservationbytes.com/2021/05/20/killing-feral-cats-quickly-and-efficiently/
I want to cull even non-feral ones, like these...
In most places which have these laws, any cat which is allowed to roam free is considered feral unless it has a collar or something.
