What can be fed to a mouse? - in detail

Mice thrive on a diet that balances carbohydrates, protein, fat, fiber, vitamins, and minerals. Commercial rodent blocks or pellets supply the necessary nutrients in a consistent ratio and should form the core of daily intake.

Fresh items can supplement the base diet:

  • Small pieces of apple, carrot, or broccoli (remove seeds and cores)
  • Cooked, unseasoned lean meat such as chicken or turkey
  • Hard‑boiled egg, finely chopped
  • Low‑fat plain yogurt (no added sugar)

Protein‑rich treats, given sparingly, include:

  • Mealworms or dried insects
  • Small amounts of cottage cheese
  • Unsalted, unflavored nuts (almonds, peanuts) broken into tiny fragments

Fiber sources support digestion:

  • Whole‑grain cereal flakes
  • Oats, unsweetened
  • Small amounts of bran

Foods that must be excluded because they cause toxicity or digestive distress:

  • Chocolate, caffeine, nicotine
  • Citrus peels, onions, garlic
  • Raw potatoes or green tomatoes
  • Processed snacks high in salt, sugar, or fat
  • Alcohol and any fermented products

Feeding guidelines:

  1. Provide fresh water at all times; replace daily.
  2. Offer commercial pellets in a measured amount (approximately 3‑5 g per 30 g body weight).
  3. Introduce fresh foods gradually, monitoring for adverse reactions.
  4. Remove uneaten fresh items after a few hours to prevent spoilage.
  5. Adjust portions based on activity level, age, and health status.

By adhering to these recommendations, a mouse receives a nutritionally complete regimen while minimizing the risk of illness.
