What Do Pet Rats Eat?

When it comes to feeding pet rats, it’s important to provide a balanced diet that offers a variety of nutrients. The main component of their diet is a high-quality grain mix, which can be found in pet stores. This mix usually contains a variety of grains, seeds, and nuts, providing a good source of carbohydrates and essential fatty acids.

It’s recommended to purchase a commercial grain mix rather than making it yourself, as pet food manufacturers take into account the nutritional needs of the rats and create mixes with the correct ratios of ingredients. An adult rat typically consumes about 30 grams of grain mix per day.

In addition to the grain mix, it’s important to include fresh fruits and vegetables in their daily menu. Rats enjoy a variety of vegetables such as leafy greens (spinach, kale, and lettuce), bell peppers, carrots, broccoli, and cucumbers. Fruits like apples, bananas, berries, and melons can also be given as occasional treats.

Protein is another crucial component of a rat’s diet. While the grain mix provides some protein, it’s beneficial to supplement their diet with additional sources. Some protein-rich foods that can be given to rats include cooked chicken or turkey, hard-boiled eggs (without the shell), tofu, and small amounts of cheese or yogurt. Be sure to offer these foods in moderation and ensure they are cooked, as rats can have difficulty digesting raw meat or eggs.

Forbidden Foods for Pet Rats

While rats can eat a wide variety of foods, there are some that should be strictly avoided as they can be toxic or harmful to their health. Here are some of the foods you should never feed your pet rats:

Chocolate: Chocolate contains theobromine, a substance that is toxic to rats and can cause serious health problems like heart issues and seizures.

Caffeine: Similar to chocolate, caffeine is toxic to rats and can lead to cardiac problems, muscle tremors, and even death. Avoid giving them coffee, tea, or any caffeinated beverages.

Raw Beans: Raw beans, such as kidney beans, contain a substance called lectin, which can be harmful to rats. It’s important to cook beans thoroughly before giving them to your pets.

Citrus Fruits: Citrus fruits like oranges, lemons, and grapefruits contain high levels of citric acid, which can cause gastrointestinal upset and digestive issues in rats. It’s best to avoid feeding them citrus fruits altogether.

Raw Potatoes: Raw potatoes contain solanine, a toxic substance that can be harmful to rats. Ensure potatoes are properly cooked before offering them to your pets.

Sugary and Salty Foods: Rats have sensitive digestive systems, and foods high in sugar or salt can cause health problems. Avoid giving them candies, chips, cookies, or any processed foods that contain excessive amounts of sugar or salt.

Onions and Garlic: Onions and garlic contain compounds that can damage a rat’s red blood cells and cause anemia. It’s best to keep these foods away from your pet rats.

It’s always important to research and double-check before introducing new foods to your pet rats’ diet. Some foods that are safe for humans may not be suitable for rats, so it’s better to be cautious and consult with a veterinarian if you have any doubts.

Health Tips and Recommendations

In addition to providing a balanced diet, there are some general health tips and recommendations to keep in mind for your pet rats:

Water: Always make sure your pet rats have access to clean, fresh water. Avoid using water bottles with metal sippers, as rats’ teeth can get stuck in them. Instead, opt for water bottles with plastic spouts or use a water dish that can be easily cleaned.

Introduce New Foods Gradually: When introducing new foods to your pet rats’ diet, do it gradually to monitor if they have any adverse reactions or allergies. Start with small amounts and observe their behavior and stool consistency for any changes.

Age and Reproductive Status: Keep in mind that rats have different nutritional requirements depending on their age and reproductive status. Young rats and pregnant or nursing females may require additional protein and nutrients for healthy growth and development.

Regular Vet Check-ups: Just like any other pets, regular veterinary check-ups are important for your pet rats’ overall health. Your veterinarian can provide specific dietary recommendations and address any concerns or health issues.

Feeding Schedule: It’s best to establish a consistent feeding schedule for your pet rats. Divide their daily food into two to three meals and provide fresh food at the same time each day. This can help with digestion and prevent overeating.

Hygiene: Clean your pets’ food dishes and water bottles regularly to prevent bacterial growth and contamination. Dispose of any uneaten or spoiled food promptly.


Proper nutrition is essential for the health and well-being of your pet rats. By providing a balanced diet that includes a high-quality grain mix, fresh fruits and vegetables, and protein supplements, you can ensure that your pet rats receive all the necessary nutrients for optimal health.

Remember to avoid feeding them toxic or harmful foods like chocolate, caffeine, raw beans, and citrus fruits. Follow the recommended feeding tips and incorporate regular veterinary check-ups to keep your pet rats happy and healthy.
