Did You Know Tomato Leaves Are Toxic to Hamsters? Some "Healthy" Foods Can Be Deadly!

Tomatoes may be a staple in our healthy diets, but when it comes to your hamster — it’s not that simple.
While the ripe tomato fruit is safe in moderation, the leaves and stems are highly toxic to hamsters. The culprit? A natural compound called tomatine.
 

Can Hamsters Eat Tomatoes?

Yes — but only the ripe red flesh, and in very small amounts.
Never feed the whole tomato, especially not the leaves or stems. These parts contain tomatine, which is poisonous to small animals like hamsters. Even a small amount can lead to symptoms like diarrhea, lethargy, or worse.
 

"Healthy" Foods That Are Actually Harmful to Hamsters

Here are some common items that look healthy but are dangerous to your little pet:

• Tomato leaves/stems: Contain tomatine, toxic
• Potato sprouts/unripe potatoes: Contain solanine, also toxic
• Onions, garlic, chives: Can damage red blood cells
• Citrus fruits (oranges, lemons): Too acidic for hamsters
• Almonds, cherry pits: May contain cyanide

Just because it’s healthy for humans doesn’t mean it’s safe for hamsters!
 

Safe Feeding Tips for Hamsters

• Stick to vet-approved vegetables like carrots, cucumbers, bok choy
• Always wash, peel, and remove seeds from fresh foods
• Offer in small portions to prevent upset stomachs
• Don’t leave large fruits or veggies in the cage — hamsters may stash and let them rot

Final Thoughts:

When It Comes to Hamster Health, Food Safety Comes First

While tomato flesh can be a rare treat, keep your hamster far away from tomato leaves and stems.
