Hamster Food Calculator
This hamster food calculator shows how much to feed your hamster each day — dry seed mix, fresh veg, fruit and protein — by species, from Syrian to dwarf to Roborovski. It also includes a seed-mix macro checker so you can test any food or DIY mix against hamster protein, fat and fibre targets.
How the Hamster Food Calculator Works
| Species | Dry food / day | Fresh veg | Protein |
|---|---|---|---|
| Syrian | 10–15 g (~1 tbsp) | ~1 tbsp daily | Pea-size 2–3x/week |
| Dwarf | 5–7 g (~1–2 tsp) | ~1 tsp daily | Pea-size 1–2x/week |
| Roborovski | 4–6 g (~1 tsp) | ~½ tsp daily | Small insect 1–2x/week |
Daily Hamster Food by Species (Chart)
The chart shows roughly how much dry food each hamster species needs per day. Syrians eat about three times as much as a tiny Roborovski — one reason you should never just fill a bowl to the same level for every hamster.
How Much Food Does a Hamster Need Per Day?
A hamster needs only a small amount of dry food each day: a Syrian about 10–15 g (one tablespoon), and a dwarf or Roborovski about 5–7 g (one to two teaspoons). On top of that, give a thumbnail-size piece of fresh vegetable daily, a pea-size protein treat once or twice a week, and fruit only as a rare treat. It is easy to overfeed, because hamsters stuff food into their cheek pouches and hide it, so the bowl looks empty when there is actually a full hoard in the bedding. The best approach is to scatter the dry food so your hamster forages for it, and to refill only when the stash runs low.
What Should Be in a Hamster’s Food Mix? (Protein, Fat & Fibre)
A good hamster mix hits three nutrition targets: protein of at least 16% (18–24% for dwarf, growing or pregnant hamsters), fat of about 4–9%, and fibre of 6% or more. The best mixes are varied — often 30 or more different grains, seeds, legumes and a protein source such as dried mealworms — rather than a cheap filler base. Many owners add a plain rat-and-mouse lab block or a few mealworms to lift the protein. Use the Seed-Mix Macros tab to check the percentages printed on your food’s label, or the figures of a homemade mix, against these targets.
Can Hamsters Survive 3 Days Without Food?
A healthy adult hamster can often survive a couple of days by living off its hidden food hoard, and because they stash so much, a short absence may not leave them truly without food. But “survive” is not “safe”: hamsters have fast metabolisms, dwarfs especially can decline quickly, and water is the bigger risk than food — a blocked or empty bottle for even a day is dangerous. Never deliberately leave a hamster for three days without checking. For any trip beyond a night, top up a large scatter of food and a full working water bottle, or far better, have someone look in daily.
What Is a Good Feeding Plan for a Hamster?
A good plan is simple and consistent. Each evening (hamsters are nocturnal), scatter the daily portion of dry seed mix in the bedding for foraging. Daily, add a small piece of fresh veg and check the water. One or two times a week, offer a pea-size protein treat such as mealworms or plain cooked chicken, and a fruit or seed treat only occasionally. Weekly, weigh your hamster and clear out any perishable food from its hoards — but leave the dry stash, since hoarding is natural and removing it causes stress. Keeping to this rhythm protects their sensitive digestion.
What Veggies Can Hamsters Eat Daily?
Safe daily vegetables, in thumbnail-size pieces, include broccoli, carrot, cucumber, courgette (zucchini), bell pepper, and a little spinach or romaine. Dandelion greens and a small amount of kale are fine occasionally. Always wash and dry veg, offer only a small piece, and remove anything uneaten within a few hours so it does not rot in a hoard. Avoid citrus fruits, onion, garlic, raw potato, rhubarb, and anything sugary, salty or processed. Introduce each new vegetable in a tiny amount first, since sudden diet changes can upset a hamster’s stomach.
