Reasons why cats cannot wear bells:

1. It affects the cat’s mood. Cats are quiet animals. There are always sounds in their ears, which will make the cat very uncomfortable and even very irritable.

2. Affect the cat’s hearing. When the sound of bells rings in a cat's ears for a long time, it will affect the cat's hearing.

3. Affect the cat’s judgment. Cats mostly judge things through hearing, and the sound of bells can affect cats’ judgment.

4. Make the cat feel uncomfortable. Because cats can also sense things through their hair, some bells have a certain weight, and hanging around the cat's neck will make it feel like something is pressing on it.

5. It will cause danger to cats. If a cat doesn’t like to wear a bell, it will keep pulling it with its claws, which can easily strangle the cat’s neck. Some cats may even bite the bell off, making it easy for them to accidentally swallow it.
