How much do domestic rats eat? - briefly
A pet rat typically consumes 10–15 % of its body weight daily, about 3–5 g of high‑quality dry pellets, complemented by fresh vegetables and water. Proper balance prevents obesity and supports dental health.
How much do domestic rats eat? - in detail
Domestic rats typically require between 10 and 15 grams of food per 100 grams of body weight each day. An adult pet rat weighing 300 grams therefore consumes roughly 30‑45 grams of combined feed daily. Caloric intake averages 60‑80 kilocalories per day for a healthy adult, with juveniles demanding up to 100 kilocalories due to rapid growth.
Nutrient distribution should approximate 60 percent carbohydrates, 20 percent protein, and 20 percent fat. A balanced diet includes:
- Commercial rodent pellets formulated for rats, providing a reliable base; offer 1‑2 tablespoons (≈ 15‑30 grams) per day.
- Fresh vegetables such as carrots, broccoli, or leafy greens; limit to 5‑10 grams daily to avoid excess water content.
- Small portions of fruit (e.g., apple or banana) once or twice a week; keep servings under 5 grams to prevent sugar overload.
- Occasional protein treats like boiled egg, cooked chicken, or mealworms; restrict to 1‑2 grams per serving.
Water must be available at all times in a clean bottle or dish. Rats drink 10‑15 milliliters per day, increasing with higher ambient temperature or diet rich in dry pellets.
Feeding schedule benefits from two‑daily portions: one in the morning and one in the evening. This mimics natural foraging behavior and helps maintain stable metabolism. Monitor body condition by feeling the ribs; a thin layer of fat over the ribs indicates appropriate intake, while prominent ribs suggest under‑feeding.
Adjustments are necessary for pregnant or lactating females, which may require up to 30 percent more calories and increased protein. Similarly, elderly rats often reduce appetite and may need softer, highly digestible foods.
Regularly inspect food for spoilage and replace uneaten portions within 24 hours to prevent bacterial growth. Maintaining the outlined quantities supports optimal health, growth, and longevity in pet rats.
