Hamsters can eat vegetables. Hamsters are omnivorous animals and can eat a small amount of vegetables. Green vegetables can supplement them with rich vitamins, trace elements and minerals and improve their immunity. But don't feed too much. Green vegetables have high water content. Eating too much will cause hamsters to have diarrhea. Green vegetables also contain too much potassium. Eating too much can easily lead to hamster poisoning. Therefore, greens should be fed to hamsters in small amounts.

Precautions for hamsters eating green vegetables:
1. Green vegetables may contain a large amount of pesticide residues. They need to be scalded with boiling water before feeding them to hamsters.
2. When feeding vegetables, you need to wipe off the water before feeding the hamster to avoid causing diarrhea in the hamster.
3. Vegetables that have been left for too long or have rotted must not be eaten by hamsters to avoid poisoning or death of the hamsters.
4. If your hamster eats green vegetables and develops diarrhea, vomiting or other adverse symptoms, it needs to be sent to a doctor immediately for treatment.
