The reasons why cats like to chew on cardboard boxes:
1. When cats are in a bad mood, they will chew on objects to vent their emotions and soothe themselves.
2. When a cat is in the teething period, its teeth are itchy, and it also wants to chew on objects. The owner can prepare molar sticks or molar toys for the cat.

3. When a cat feels bored, it may bite the cardboard box. The owner can play with it for a while or prepare some toys for it.

4. When a cat lacks trace elements, pica will occur. The owner must supplement the cat with an appropriate amount of trace elements.
5. Cats are very curious. If they are curious about a certain item, they will want to bite it.
