When the kitten is three weeks old, it can be properly fed with liquid food, and it is best to add vitamin A, vitamin D or cod liver oil.
In the weaning stage, kittens' gastrointestinal absorption and digestion function is relatively fragile. Don't completely feed cat food. The owner should feed them with cat food and milk powder.
But also pay attention to milk powder, such as baby milk powder and milk, which can't be fed to cats, because these milk powders contain a lot of lactose, which will cause cats to have diarrhea, so it is best to feed cats with special goat milk powder. In addition, during the weaning of cats, we should pay attention to the hygiene of intestines, otherwise it will easily cause diarrhea in cats.
