Why Fresh Water Matters
Rodents, like all pets, need constant access to clean, fresh water. Stale or contaminated water can lead to bacterial growth and illness. Change water daily and wash the bottle or bowl weekly with mild soap and warm water.
Water Replacement Schedule
- Daily: Empty old water, rinse the container, and refill with fresh water.
- Weekly: Disassemble the water bottle or bowl, scrub all parts, and rinse thoroughly.
- As needed: If the water looks cloudy, has debris, or has an odor, replace immediately.
Feeding Schedule by Age
| Age | Meals per Day | Portion Size (for average hamster) |
|---|---|---|
| Baby (0-4 weeks) | 3-4 small meals | 1-2 tsp pellets + milk replacer |
| Juvenile (4-12 weeks) | 3 meals | 1-2 tbsp pellets + veggies |
| Adult (12+ weeks) | 2 meals | 2-3 tbsp pellets + 1 tbsp veggies |
Adjust portions based on species and activity level. Dwarf hamsters need less; guinea pigs need more hay and vitamin C.
Essential Nutrients
Protein
Rodents need 12-20% protein. Pellets provide balanced protein. Insects can be treats for hamsters and rats.
Fat
4-8% fat is typical. Nuts and seeds offer healthy fats but in limited amounts to prevent obesity.
Carbohydrates
Whole grains like oats and barley are good. Avoid sugary cereals and fruits high in sugar.
Fiber
Guinea pigs and chinchillas require 15-20% fiber from hay. Hamsters and gerbils need lower fiber (~8-10%).
Vitamins & Minerals
Guinea pigs cannot synthesize vitamin C; provide supplements or foods rich in C (bell peppers). All rodents need calcium, but too much can cause bladder stones.
Toxic & Harmful Foods
- Chocolate, caffeine – toxic to all rodents.
- Onions, garlic – cause anemia.
- Citrus fruits – may cause mouth sores in guinea pigs.
- Raw beans/peas – contain toxins.
- Dairy – lactose intolerant.
- High-sugar treats – lead to obesity and diabetes.
Hydration Tips
Most rodents drink 10-20 ml per 100g body weight daily. For example, a 200g hamster needs ~20-40 ml. Offer water in bottles to prevent spilling. Check the ball bearing regularly.
Supplements
- Vitamin C – essential for guinea pigs, given in water or tablets.
- Probiotics – after antibiotic treatment or stress.
- Oxbow Natural Science – supplements for specific needs.
Age-Specific Feeding
Babies
Newborns rely on mother's milk. If orphaned, use rodent milk replacer (e.g., Esbilac). Transition to softened pellets around 3 weeks.
Adults
Feed commercial pellets as staple (80-90% of diet). Add fresh vegetables (10-20%) and occasional fruit treats. Limit sunflower seeds.
Seniors
Older rodents may need softer food, more fiber, and weight management. Reduce protein slightly (15% max). Offer easy-to-eat foods like cooked squash.
Signs of Healthy Diet
- Shiny coat and bright eyes.
- Consistent weight and good appetite.
- Normal droppings (firm and regular).
- Active behavior.
Signs of Poor Diet
- Lethargy, weight loss or gain.
- Dull coat, skin issues.
- Diarrhea or constipation.
- Teeth grinding (pain).
- Excessive thirst or urination (diabetes).
Regular vet check-ups help monitor health. Adjust diet gradually over a week to avoid digestive upset.
