What can I feed a mouse in a domestic setting? - in detail

A domesticated mouse requires a balanced diet that supplies carbohydrates, protein, fat, vitamins and minerals. Commercially formulated mouse pellets or blocks provide a complete nutritional base; they should constitute the majority of the daily intake.

Fresh foods can supplement pellets, offering variety and additional nutrients. Suitable items include:

  • Small pieces of apple, banana, or pear (remove seeds)
  • Berries such as blueberries or strawberries, offered in moderation
  • Leafy greens like romaine lettuce, spinach or kale, washed thoroughly
  • Carrot or cucumber slices, cut into bite‑size portions
  • Cooked, unseasoned lean meats (chicken, turkey) or boiled egg white for protein enrichment

Treats must be limited to prevent obesity. Acceptable occasional treats are:

  • Sunflower or pumpkin seeds (unsalted, unshelled)
  • Small amounts of plain oatmeal or whole‑grain cereal
  • Low‑fat cheese cubes or plain yogurt (no added sugars)

Foods that pose health risks and must be excluded are:

  • Chocolate, caffeine, alcohol
  • Citrus fruits, raw onions, garlic
  • Processed snacks, salty or sugary foods
  • Nuts with high fat content, moldy or spoiled produce
  • Dairy products beyond occasional low‑fat options, as many mice are lactose intolerant

Water should be available at all times in a clean, spill‑proof bottle. Replace daily and disinfect the bottle weekly.

Feeding schedule: provide pellets continuously, replenish fresh foods daily, and remove uneaten perishables after 24 hours to prevent spoilage. Monitor body condition; adjust portions if weight gain or loss occurs.
