Solutions for kittens that are too young to use the litter box:

1. Let cats who know how to use cat litter teach. Kittens are usually taught how to use cat litter to go to the toilet by their mother cats. If there is no mother cat around, you can find a cat that knows how to use cat litter and let the kittens watch and learn.

2. Odor induction. You can use a pet-specific fecal attractant, or put the kitten's excrement into the litter box, so that when the cat wants to urinate again, it will look for the smell and find a place to urinate.

3. Look for the pattern of cat excretion. When you see a kitten wanting to urinate, you can put the kitten into the litter box and wait until it has finished excreting before letting it out. Over time, the cat will know where to urinate.

4. Food rewards. When the cat uses cat litter correctly, reward the cat with treats to let it know that it is the right thing to do. If you persist like this for a while, it will learn to use cat litter.

5. Replace cat litter. Some cats don’t like going to the toilet in the litter box because they don’t like the material and smell of the litter. It’s best to use unscented cat litter, as the cat will like it better.
