Is Kaytee Gourmet rat and mouse food okay for my hamster's diet?

Hello, This is a great question. This food should be fine for your hamster since they have similar teeth to rats and mice. However, seeds are very high in fat and have little vitamin content. Therefore, they’re considered “junk food” and really should be a minority of the diet. A rodent block type food (the ones that are very boring looking, tan, and all look the same) would be idea as he majorly of the diet. These rodent blocks come in different sizes for rats vs hamsters but they’re likely the same formulation.
