The kitten has just brought it home, so it is not afraid of being unfamiliar and unsanitary. Therefore, the use of cat litter should be taught from the beginning. Once it develops a bad habit (such as peeing on a stool), it will have a headache in the future.
First of all, I want to tell you that kittens are smart and can teach quickly with cat litter. Generally, a kitten will remember "Oh, I want to go to the toilet here" within two or three times. When kittens first come back, if they are not taught well, they will basically defecate everywhere, even if they pull in the litter box, it can only be considered a mistake.
Therefore, before you bring it back, the trash can should be ready. As soon as you enter the door, you should hold the kitten and plane it with your claws. The clever kitten knows what it means at a glance.
Education about cats:
Of course, some kittens don't care what you are doing at all, and even defecate everywhere after teaching. At this time, you need to educate it. (corporal punishment is not allowed. The important thing is to educate it carefully and let it know that you are unhappy. It is said that cats have poor memory, so we must seize the on-site education.
Remember, teaching kittens to use cat litter must be taught as soon as possible. If you are lazy, let it solve for a period of time, it will release the "toilet" smell everywhere at home, and it will be confused itself, and it will be difficult to get rid of bad habits over time.
