Honey Treat Yogurt My Hamster Is Refusing To Eat Her Regular Food?

My hamster is refusing to eat her regular food? - honey treat yogurt

My hamster has eaten ice cream for two years the same meal, he was with me. He had never liked the other food that I bought.

When I started, there were, these yogurt drops and drops of honey for pet hamsters, stopped eating regular food. I have tried to stop a few days and still not eat. I thought the food packaging could be wrong, but he did not. I bought new and not as a question. What should I do?
