Solutions to the problem that German curly cats cannot use cat litter:

1. First, choose the appropriate cat litter. Some cats have never used tofu cat litter, so they can choose the more commonly used bentonite cat litter, which is closer to the look of sand. At the same time, most cats do not like scented cat litter, so owners should avoid it.

2. Place the cat litter box in a suitable location. Cats like to urinate in hidden places, and they should not be too close to where cats eat and drink.

3. Let the cat’s familiar smell appear in the cat litter. You can place your cat's waste in the litter box to let it know this is where it goes.

4. Train German curly cats to use cat litter. Ten minutes after the cat has finished eating, you can place it in the litter box and let it out after it has finished going to the toilet.

5. Reward system. When the cat uses the litter box correctly, the owner can reward the cat with small snacks to let the cat know that it is right to do so.
