Hamsters love nibbling on a range of different foods in addition to their standard pellet diets. That said, not every kind of food is safe for them, so it’s good to be clued up. As for tomatoes, hamsters can eat a little bit of ripe tomato on occasion, but these fruits shouldn’t be a mainstay of their diets. Read on to learn more.
Are Tomatoes Safe for Hamsters?
If fed completely ripe, in small amounts, and only from time to time to hamsters over 12 weeks of age, tomatoes are okay for hamsters to eat. However, avoid feeding green, unripe tomatoes or any parts of the tomato plant, as this may make your hamster sick.
It’s also essential to bear in mind that tomatoes are acidic, so feeding a hamster too much could cause digestive upset. In severe cases, the diarrhea caused by an upset stomach can be life-threatening if your hamster becomes dehydrated and can’t rehydrate itself. Hamsters are very little and can quickly be affected by dehydration as a result of diarrhea, so be careful.
This is why it’s so crucial to stick to feeding very small amounts of tomato as a treat on occasion if your hamster has a taste for them. They’re not ideal for inclusion in your hamster’s daily diet.
What Do Hamsters Eat?
The base of a hamster’s diet should be hay and a pellet mix, though it’s wise to avoid muesli-style mixes. These might look pretty, but as explained by the PDSA, it’s common for hamsters to pick out the fibrous pieces and only eat the sugary pieces, which can lead to obesity and dental problems.
A complete pellet mix from a high-quality brand is a better choice. You can ask your vet for diet recommendations if you’re not sure which brand of pellets to choose.
Hamsters are omnivorous animals, so they enjoy a wide range of different food types in addition to their regular pellet-style diet, including timothy hay, small amounts of vegetables and fruits, seed mix (hamsters eat seeds in the wild but they’re high in fat, so moderation is best), and even protein sources like mealworms and small amounts of boiled egg as treats now and again.
Avoid overindulging your hamster in fruits and vegetables; a teaspoon’s worth per day is plenty. Too much fresh produce can cause diarrhea, which can be dangerous for hamsters. For some variety, you can cut different fruits and vegetables into very small pieces.

Hamsters love variety; it keeps things interesting and helps them reap multiple nutritional benefits. As a guideline, here are some examples of safe foods (to be fed in small amounts) for hamsters to supplement their pelleted diet with. Below that, we’ll share some popular treats to feed on occasion. Don’t forget to wash fresh produce before feeding it to your hamster!
Reminder: A teaspoon’s worth of fresh foods per day is enough for hamsters. Offering too much can cause a stomach upset. If fruits contain any seeds, stones/pits, or leaves, remove these before feeding.

Hamster Feeding Fun
Hamsters like to have a good time as much as the next furry mammal, and greatly appreciate variety and little challenges. Feeding time is perfect for offering your hammy some mental stimulation.
- Vary the fruits, veggies, and herbs you offer.
- Stuff hay in toilet roll tubes or a box and let your hamster munch it out.
- Hide treats (like little bits of safe fruits, veggies, and greens) in tubes or boxes.
- Put some of the food pellets in different areas around the cage so your hamster can search for them.
- Provide items your hamster can gnaw and chew on like wooden hamster chew toys, cardboard, coconut shells, pumice stone, sun-bleached loofah, hay cubes, and seagrass. Gnawing mentally stimulates your hamster and helps keep their teeth healthy.
Final Thoughts
To recap, hamsters can eat tomatoes, but only in very small amounts and on occasion. When you introduce new fresh foods, be sure to do so gradually and in moderation. Keep an eye on your hamster to make sure they don’t develop diarrhea or other changes.
If your hamster does experience diarrhea, please contact your vet, and ensure your hamster has access to clean water to rehydrate. A needle-free syringe can be useful for getting your hamster to drink until you can get to the vet.
