In the walnut diary, there is time to pay attention to eating. Her meal time is eight o'clock in the morning, twelve o'clock at noon and six o'clock in the afternoon. Of course, the time is not particularly accurate, but the difference will not be particularly great. At other times, under normal circumstances, she will not eat.
Because walnuts are eaten every day, you can prepare more food in the refrigerator, avoiding the situation that you have nothing to eat because you have no time to play with walnuts.
Some people are interested in whether walnuts will starve to death without eating for days. In fact, even if people don't prepare food for walnuts for many days, she won't starve to death, but the consequences are not very clear. After all, no one has done this, and bold speculation will lose a lot of intimacy.
