Teaching kittens to use cat litter should start from the following aspects: choosing the right cat litter box, putting it in the right place, monitoring the behavior of kittens, cleaning the cat litter box frequently, and cleaning the cat litter box frequently.

1. Choose a suitable litter box: make sure that the litter box is suitable for kittens and shallow enough for kittens to enter. In addition, choose the appropriate cat litter, such as ordinary sand or caked cat litter.

2. Put the litter box in the right place: put the litter box in the place where kittens often appear, such as living room, bedroom or bathroom. This will make it easier for kittens to find litter boxes and reduce misunderstandings.

3. Monitor the kitten's behavior: When you find that the kitten wants to urinate or defecate, please take it to the litter box immediately. If it starts digging cat litter or crouching down, it means it's time to use the cat litter basin.

4. Clean the litter box frequently: Both young cats and adult cats like to use clean litter boxes. In order to make kittens develop good habits, please clean and replace cat litter regularly and keep the area around the cat litter basin clean and tidy.

5. Clean the litter box frequently: When the kitten successfully uses the litter box, please give it a little reward, such as food, toys or caress. This will encourage it to use garbage bins more in the future.
