Here are scientifically-backed feeding frequency recommendations for hamsters, adjusted by age and needs:

1. Feeding Frequencies by Age
Baby Hamsters (0-2 Months)
4-6 feedings daily with small portions, prioritizing easy-to-digest baby hamster food.
Each serving is about 1-2 grams (roughly the size of a pinky nail).
Adult Hamsters (2-18 Months)
1-2 feedings daily at fixed times (e.g., 8:00 AM and 8:00 PM).
3-5 grams of main food per feeding, ideally consumed within 10 minutes.
Senior Hamsters (18+ Months)
2-3 feedings daily with softened food (e.g., crushed pellets or steamed pumpkin).
2. Key Precautions
Nocturnal Feeding
Feed between 6:00-7:00 PM for optimal results, aligning with their natural circadian rhythm.
Supplementary Diet Balance
Fruits & veggies: 2-3 times weekly, 1 thumb-sized portion each.
High-protein treats (e.g., mealworms): 1-2 pieces weekly to prevent obesity.
Water Management
Change drinking water daily, more frequently in summer.
3. Common Mistakes to Avoid
Overfeeding
Hamsters hoard food—stale leftovers can cause diarrhea.
Human Food Taboos
Avoid sugary, salty, or processed foods with additives.
Pro Tip: Adjust portions based on your hamster’s size and activity level. Adult daily intake typically ranges from 5%-10% of their body weight.
