What should domestic rats not eat? - in detail
Pet rats require a diet that excludes several common foods because they can cause acute poisoning, chronic health problems, or digestive upset. The following items should be avoided entirely.
- Chocolate, caffeine‑containing products, and any candy with theobromine – toxic to rodents, leading to tremors, seizures, or death.
- Raw or undercooked beans, especially kidney beans – contain phytohaemagglutinin, which can cause severe vomiting and diarrhea.
- Citrus fruits and juices – high acidity irritates the stomach lining and may lead to ulceration.
- Processed meats, bacon, and deli slices – high salt and preservative content strain kidneys and can trigger hypertension.
- Avocado flesh and pits – contain persin, a compound that can cause respiratory distress and heart damage.
- Nuts in large quantities – excessive fat leads to obesity, liver disease, and pancreatitis.
- Dairy products such as milk, cheese, and yogurt – many rats are lactose intolerant; consumption results in diarrhea and dehydration.
- Sticky or hard candies, gum, and chewing gum – pose choking hazards and can adhere to teeth, causing dental problems.
- Seeds from apple, cherry, peach, or plum pits – contain cyanogenic glycosides that release cyanide when metabolized.
- Alcohol and any fermented beverages – depress the central nervous system and can be fatal even in small doses.
- High‑sugar treats, including fruit-flavored yogurts and sweetened cereals – promote rapid weight gain, insulin resistance, and dental decay.
In addition to the items listed, any food that is moldy, spoiled, or contains artificial sweeteners (especially xylitol) must be discarded. Fresh vegetables and fruits should be offered in moderation, washed thoroughly, and introduced gradually to monitor tolerance. A balanced diet of high‑quality rat pellets, supplemented with safe fresh produce, provides the nutrients required for optimal health without exposing the animal to preventable dangers.
