Hamsters don't need to peel sunflower seeds before eating them. Hamsters can use their well-developed incisors to crack open the shells of sunflower seeds. This not only helps them wear down their teeth but also exercises the sharpness of their teeth.

Precautions When Feeding Hamsters Sunflower Seeds
Choose Raw Sunflower Seeds: Don't feed hamsters roasted sunflower seeds or sunflower seeds with various flavors, because these may cause allergies or gastrointestinal intolerance in hamsters, leading to symptoms such as diarrhea.
Feed in Moderation: Sunflower seeds have a relatively high oil content. They cannot be fed as the main food but can only be given as snacks in small amounts every day to avoid problems like excessive internal heat and obesity in hamsters.
Pay Attention to the Sharp Parts of the Sunflower Seed Shells: When feeding, you should help the hamsters peel the shells and break off the sharp tips of the sunflower seeds to prevent the hamsters' gastrointestinal tracts from being injured.
Dietary Suggestions for Hamsters
The diet of hamsters should mainly consist of hamster food, and sunflower seeds can only be fed as snacks in small quantities. In addition, hamsters are omnivorous animals. You can also supplement their nutrition and water by feeding them fruits and vegetables regularly. However, be careful not to feed fruits and vegetables with too much water content, as this may cause diarrhea.
