The reasons why cats scratch the ground:
1. Cats scratching the ground may be because their nails are too long. If you want to sharpen their claws, owners can trim their cats' nails regularly.
2. When cats are in a bad mood, they will also vent their emotions by scratching the ground and soothe themselves.
3. When a cat feels bored, it will also dig on the ground to pass the time. The owner should prepare more toys for the cat.
4. When a cat’s toes are injured or itchy, it will dig on the ground. The owner needs to check whether there are any abnormalities in the cat’s claws. If there are any abnormalities, seek medical attention in time.
5. When a cat doesn’t like eating a certain food, it will also scratch the ground. This is a protest to the owner and wants to change the food.
