1. For geomantic numerology, cats represent wealth. If a stray cat comes to the door automatically, it means that there will be unexpected wealth. If your cat is lost, it also means that there will be wealth loss. So the cat at home can't be easily given away. Give people money, even if it is one yuan. From this perspective, killing a cat with a car means that your upcoming wealth has been sent away.
2. If you accidentally drive and kill a cat, you must first make sure whether the cat has an owner, give the owner some compensation, buy the cat from the owner, and then hang the cat on the tree. Drive carefully, drive slowly and be careful in your words and deeds.
