My neighbor has a cat, but it always runs to my sand pile to poop, what should I do?

1. Cover the sand pile: put a protective layer on the surface of the sand pile, such as plastic film or a grid, so that the cat can't have direct access to the sand pile and reduce the chance of pooping.

2. Use deodorant: Spray some odors around the sand pile that cats don't like, such as orange peel, lemon juice, or chili water. This can create an aversion in cats, thus reducing their desire to poop on the sand pile.

3. Set up a litter box: Offer your neighbors to set up a special litter box near their own homes, tell them about the nuisance of cats pooping on your sand piles, and explain that the practice is good for both parties.

4. Install protection: put some barriers around the sand pile, such as a low fence or barbed wire, to stop cats from entering the sand pile area
