What should not be fed to rats? - in detail
Rats require a diet that excludes several categories of food because of toxicity, digestive incompatibility, or nutritional imbalance.
High‑fat and high‑sugar items such as chocolate, candy, and fried snacks contain compounds that can cause liver damage, obesity, and dental problems.
Citrus fruits, including oranges, lemons, and grapefruits, introduce excessive acidity, leading to gastrointestinal irritation and potential electrolyte disturbances.
Raw or undercooked beans, especially kidney beans, contain phytohemagglutinin, a lectin that induces severe vomiting and diarrhea.
All dairy products, even small amounts of cheese or milk, lack the necessary lactase enzymes in rats, resulting in persistent diarrhea and dehydration.
Processed meats, cured sausages, and deli slices contain high sodium levels and preservatives that strain renal function and elevate blood pressure.
Alcoholic beverages and any fermenting substances cause rapid intoxication, respiratory depression, and can be fatal at low doses.
Caffeinated drinks, energy drinks, and foods containing caffeine stimulate the cardiovascular system, produce arrhythmias, and increase stress hormone release.
Artificial sweeteners, particularly xylitol, trigger rapid insulin release, leading to hypoglycemia and potential liver failure.
Salty snacks, potato chips, and pretzels contribute to electrolyte imbalance, kidney overload, and hypertension.
Avocado flesh and pits contain persin, a toxin that can cause respiratory distress and cardiac issues in rodents.
Onion, garlic, leeks, and chives belong to the Allium family; their sulfur compounds cause hemolytic anemia by damaging red blood cells.
Raw eggs present avidin, a protein that binds biotin and creates a deficiency affecting skin, coat, and neurological health.
Moldy or spoiled food introduces mycotoxins, which impair liver function and suppress the immune system.
In summary, a safe rat diet consists of fresh vegetables, limited fruits, high‑quality rodent pellets, and occasional protein sources such as cooked lean meat or boiled eggs, while avoiding the items listed above to maintain optimal health and longevity.
