Can dwarf hamsters eat dry corn and dry peas from hamster food for example fiesta or no since they contain sugar?

Dwarf hamsters can eat dry corn and dry peas in moderation, as these are often included in commercial hamster food mixes like Fiesta. While they do contain some sugars, the amounts are generally low enough that they won't harm your hamster if given occasionally. However, it's important to ensure that the majority of their diet consists of high-quality pellets and fresh vegetables to maintain their health. Always monitor your hamster's overall diet and weight to prevent obesity.
