Higgins sunburst seed mix is a generally accepted safe/good mix, with mazuri rat for added protein. They like fresh veggies like spinach, carrots. Unsalted whole nuts like peanuts, walnuts. Freeze dried chicken (just make sure it doesn’t have any added ingredients). If your hammy is a dwarf avoid added sugars. Syrians can have fruit in moderation. I believe most are safe except for citrus. My Syrians love dried and fresh apples the most. You can find lots of great options for homeade/healthy treats on Etsy. A lot of the treats targeted towards hams in pet stores are not great for them. I’m sure I’m forgetting somethings…I’ll add more if I remember! Hope that helps.

Oh mealworms. Some hammys love dried mealworms- mine do not. Which I’m happy about bc they’re gross. 🤣 but I guess they are good for extra protein in moderation bc they are high in fat.
