Dried breadworms have no nutrition. Rats and mice don't like to eat either. I suggest going to the flower and bird market to buy live breadworms. Bread shape is hamster's favorite. Give him as much as you can, and he will hide if he can't finish eating. But breadworms don't advocate giving hamsters more food, just like melon seeds. Eating too much and gaining weight will do harm to rats and mice. They don't know how to keep in good health, and they will get sick. So bread bugs should be a reward. For example, if you approach him today and he doesn't bite you, you can reward him with one or two. Don't eat too much. In addition, the mouse has just given birth to a baby, so you can give more, for example, three or four. When the mouse grows up, it can eat one for the mouse every day. Don't give more to the mother mouse in the future, one day 1 piece. Reward two occasionally.
