These are typical average values. Use "Enter from label" to match your exact product.
Look for "Calorie Content" or "Metabolizable Energy (ME)" — usually near the ingredients list on the back or side of the bag or can. It reads something like "3,500 kcal/kg" or "350 kcal/cup". Match the toggle above to whichever unit your label shows. Can't find it? Use the list option — it's accurate enough for most foods.
We'll subtract this from the daily food portion.

About the Dwarf Hamster
Dwarf hamsters (Campbell's, winter white, Roborovski) are tiny and, crucially, prone to diabetes — so their diet must be strictly low-sugar with no fruit. A typical adult weighs about 0.02–0.05 kg.
How much should a Dwarf Hamster eat?
Calorie needs use the veterinary formula 70 × weight(kg)0.75 (the Resting Energy Requirement), multiplied by a lifestyle factor of ×1.5 for a typical hamster at the life stage shown. Enter your own animal's details in the calculator for an exact figure.

What to feed
A good hamster diet is a quality seed-and-pellet mix as the base, plus small amounts of fresh vegetables and occasional protein (a mealworm or piece of plain cooked egg). Syrian and dwarf hamsters differ: dwarves are prone to diabetes and need low-sugar diets with no fruit.
Hamsters are nocturnal and eat mostly at night. Offer a measured daily portion — roughly a tablespoon for a Syrian, a teaspoon for a dwarf — and remove perishable fresh food before it spoils in the hoard.
