πŸ“ Summary

Several common foods are unsafe for hamsters, almonds (cyanide), tomato leaves (toxic), unwashed produce (pesticide), sugary food (obesity), onion (blood harm), and seasonings (gut irritation).

1 Unsafe Foods

Almonds seem like a nice nut but contain trace cyanide that can poison and kill a hamster. Tomatoes are fine in small amounts, but the leaves are highly toxic; always remove them from cherry tomatoes. Unwashed produce carries pesticide residue that, though tiny, can kill a small hamster.

2 More to Avoid

Very sugary food causes obesity, breathing trouble, and shorter life. Onion’s disulfides harm all pets, so keep it and its smell away. Seasonings, especially spicy ones, irritate the gut and add preservatives. Stick to safe, well-managed foods and read more on hamster diet.
