There is probably a family in your neighborhood that calmly lets their cat roam freely.
You can't explain it to an animal, so other people's cats can easily enter your garden and do their dirty deeds there.
How should you act in such a situation to prevent your neighbor's cat from turning your territory into a litter box, a place for games or hunting?
The best way to resolve the problem peacefully is to talk to the cat's owners. They may not even realize that their pet is causing so much trouble to others.
But if the cat’s owners do not take any measures, it is worth using other methods.
Go to other neighbors - it is quite possible that the four-legged hooligan does not give them peace, too. Write a collective letter and hand it to the "guilty" neighbor with a promise to go further if necessary.
No one can take better care of your property than you, so try to make it unsuitable for cat walks by planting herbs that cats don't like or scattering lemon peels around the perimeter.
The last resort is to get your own cat, which will zealously defend its territory from strangers.
