If the kitten is too picky about food, she will only eat egg yolk and nothing else in the morning. It will definitely not work after a long time. Can only be fed with other supplementary foods. If your kitten is young (for example, less than three months old), you must only eat egg yolk once a day, only one-third of the egg yolk at a time, and not more than twice a week, otherwise it will do harm to the kitten's stomach, for example. Generally, kittens can feed cat food because it is relatively easy to digest. If it doesn't eat cat food, don't feed it egg yolk. If it is hungry, it will eat by itself. After a while, it will get used to it. Egg yolk is not the main food for kittens, but it is eaten when the food improves. In short, make the kitten hungry. It will be hungry if it doesn't eat, so it won't be picky about food.
