What can be fed to mice and rats? - briefly
Commercial rodent pellets, supplemented with small amounts of fresh fruits, vegetables, and protein sources such as boiled egg or mealworms, provide a balanced diet for laboratory and pet mice and rats. Toxic items—including chocolate, caffeine, citrus peels, onions, and raw beans—must be excluded.
What can be fed to mice and rats? - in detail
Mice and rats require a balanced diet that supplies protein, carbohydrates, fats, vitamins, minerals, and fiber. Commercially prepared rodent pellets are formulated to meet these nutritional standards and should form the core of the diet. Pellets provide consistent nutrient ratios, reduce the risk of deficiencies, and minimize waste.
Fresh produce can complement the base diet. Suitable items include:
- Small pieces of apple, carrot, broccoli, or cucumber (remove seeds and pits).
- Leafy greens such as spinach, kale, or romaine lettuce (offer in moderation to avoid excess calcium).
- Berries (blueberries, strawberries) as occasional treats.
Grains and legumes add carbohydrate and protein content. Acceptable options are:
- Cooked oatmeal, rice, or quinoa (cooled to room temperature).
- Cooked lentils or beans (well rinsed, no added seasoning).
Protein sources enhance growth and maintenance. Viable choices consist of:
- Cooked chicken, turkey, or lean beef (no skin, bones, or seasoning).
- Hard‑boiled eggs (peeled, chopped).
- Low‑fat cottage cheese or plain yogurt (unsweetened).
Treats may be offered sparingly to maintain weight control. Examples include:
- Small amounts of unsalted nuts (almonds, peanuts) – limit due to high fat content.
- Plain popcorn (air‑popped, without butter or salt).
Foods that pose health risks must be excluded. Dangerous items are:
- Citrus fruits (high acidity can cause gastrointestinal upset).
- Chocolate, caffeine, nicotine, or alcohol (toxic to rodents).
- Processed foods containing artificial sweeteners, especially xylitol.
- Raw potatoes, raw beans, or any plant material with known toxins (e.g., nightshade family).
Water should be available at all times, preferably via a clean bottle with a sipper tube to prevent contamination. Regularly inspect water sources for blockage or leakage.
Monitoring body condition and adjusting portion sizes ensures optimal health. Replace spoiled food promptly and maintain a consistent feeding schedule to reduce stress.
