Rats are highly adaptable creatures with diverse dietary habits that allow them to thrive in almost any environment. Since they can eat various kind of foods, they thrive as both pets and pests. While pet rats require a balanced diet to maintain their health and longevity, wild rats will eat nearly anything they can find, from discarded human food to natural vegetation.In this article, we will get to know everything you need to know about what rats eat, highlighting the differences in what wild rats, pet rats, and household pests consume in various environments.
While pet rats have diverse dietary needs, it’s equally important to avoid feeding them harmful foods that could jeopardize their health. Foods like chocolate, onions, garlic, caffeine, and alcohol are toxic to rats, leading to severe health issues or even death. A balanced diet with safe, nutritious foods is key to keeping pet rats healthy and thriving.
Rats are resourceful foragers, and once they find a reliable food source in your home, they are likely to stay. Ensuring proper food storage and cleaning up spills can help prevent an infestation. 
However, not all fruits are safe for rats. Grapes, for instance, have been linked to kidney issues in rodents if consumed in large quantities. Citrus fruits like oranges, lemons, and limes should also be avoided, as their acidity can upset a rat’s stomach, and certain compounds found in citrus may be harmful to male rats. It’s important to remove seeds and pits from fruits like apples, as they contain small amounts of cyanide, which can be toxic to rats. Offering a balanced variety of fruits ensures your pet rat stays healthy and happy.
While cannibalism is rare in pet rats, it can occur if a rat dies suddenly and its cage mates instinctively consume the body. This is often a survival response rather than aggression. If this behavior is observed in pet rats, it may indicate overcrowding, stress, or nutritional deficiencies, so it’s important to provide a balanced diet and adequate space for them.
If these methods do not improve the situation, it might be a sign of a full-fledged rat infestation. Seek professional pest control help if things seem to go out of control. Our team can provide a customized approach to protect your home effectively.
