First, the education of female cats is very important.
It turns out that cats are all wild, so they need certain wild hunting and survival skills. Before cats were used as pets by humans, these survival skills were taught by female cats. So now many cats can't catch mice, can't go to the toilet, and it takes some time to learn to fly over the eaves and walk over the walls. These actually need education. But now sometimes when raising cats, there are only kittens, and there is no mother cat to teach them, so they need the owner's education and guidance.
Second, the kitten has never seen the stairs.
This requires climbing or skill, so the kitten can't judge whether she can do it or not, so she will hesitate at the stairs. If the owner has taught it, the kitten can judge that she can go down the stairs or go down the stairs in other ways. If you don't teach, the kitten is afraid and can't judge whether it is safe, so naturally she doesn't dare to go downstairs. Just like a kitten eating canned food or snacks, it is afraid to eat if it has not been seen at first. As long as the owner feeds it and it tastes delicious, it naturally likes it. So is going downstairs. As long as the kitten can judge that it is safe to go down the stairs, it will naturally learn gradually.
As owners, we should be more patient with kittens, observe their daily performance, find that kittens can't go down stairs, try to teach them patiently, and then try to solve problems patiently, then we must be a qualified owner.
