I like to use mealworms, pumkin seeds, dried shrimp, fresh vegetables, walnut, flax seeds (linseeds), chia seeds, baby food (hamster safe, no garlic, spices, pork) and I also like to smear peanut butter on my finger. I like to do this beacause it’s a great way to get your hamster used to you. Make sure it’s just a smear on your finger so he has to lick it off. Try to get a peanut butter that has only roasted peanuts. Make sure not to get a peanut butter with xylitol it may be toxic to hamsters.
