What should not be given to mice? - briefly

Mice must not be fed chocolate, caffeine, alcohol, avocado, raw beans, onions, garlic, moldy or spoiled foods, and any high‑fat or high‑salt processed snacks. These substances contain toxins, stimulants, or irritants that can cause organ failure, severe digestive upset, or death.

What should not be given to mice? - in detail

Mice have specific dietary needs; certain foods and substances can cause acute toxicity, chronic health issues, or fatal outcomes. The following categories should be excluded from their regimen:

  • Chocolate and caffeine‑containing products – methylxanthines interfere with cardiac function and can lead to seizures.
  • Raw or undercooked beans (especially kidney beans) – contain phytohaemagglutinin, a potent toxin that damages the gastrointestinal lining.
  • Citrus peels and high‑acid fruits – cause digestive irritation and can erode tooth enamel.
  • Processed meats, salty snacks, and foods high in sodium – promote dehydration, kidney strain, and hypertension.
  • Dairy products – many adult mice lack lactase, resulting in severe diarrhea and malabsorption.
  • Sugary candies and artificial sweeteners (e.g., xylitol) – rapid blood‑sugar spikes, and xylitol can cause hypoglycemia and liver failure.
  • Alcohol and fermented beverages – depress central nervous system activity, leading to respiratory failure.
  • Petroleum‑based products, oils, and grease – impair lipid metabolism and can cause hepatic toxicity.
  • Moldy or spoiled food – introduces mycotoxins that damage organs and suppress immune function.
  • Metallic objects (e.g., aluminum foil, wire) – risk of ingestion, leading to gastrointestinal obstruction or perforation.

In addition to food, avoid providing:

  • Aromatic essential oils and strong fragrances – inhalation irritates respiratory passages.
  • Household cleaning agents, disinfectants, and pesticides – contain chemicals that are corrosive or neurotoxic.
  • Plastic or rubber toys treated with phthalates – endocrine disruptors that affect reproductive health.

When constructing a diet, prioritize commercially formulated rodent pellets, fresh vegetables (e.g., carrots, broccoli), and limited amounts of whole grains. Regularly monitor for signs of distress—vomiting, lethargy, weight loss—and eliminate any suspect items immediately.
