My hamster ate Kaytee Forti-Diet Pro Health Hamster food for its entire life. She lived to be a very old age for a hamster and never had any health issues. I attribute this to her diet. She was always happy and energetic and had beautiful shiny hair. The food was very affordable compared to other brands and was highly recommended by the pet store that I bought my hamster from. The directions are very clean on the bag so you know exactly how and what you are feeding your pet. I would highly recommend this food.
