Providing optimal nutrition is crucial for the health, well-being, and longevity of pet rats. While commercially available rat foods offer convenience, some rat owners are drawn to the Shunamite diet, a homemade approach that emphasizes variety and fresh ingredients. This article delves into the Shunamite diet for rats, exploring its principles, benefits, challenges, and practical considerations.
Understanding the Shunamite Diet
The Shunamite diet, pioneered by Alison Campbell, is a nutritionally balanced homemade diet designed to provide rats with a diverse and enriching eating experience. Unlike commercially produced pellets, which offer a consistent nutritional profile in every bite, the Shunamite diet consists of two main components: a dry base mix and a daily fresh meal.
The Base Mix
The base mix typically comprises 50-60% of the total diet and consists of a blend of whole grains, seeds, nuts, cereals, and fortified foods. It provides a foundation of carbohydrates, proteins, and fats, along with essential vitamins and minerals.
The Fresh Meal
The fresh meal, which makes up the remaining portion of the diet, consists of a variety of fresh fruits, vegetables, fungi, and cooked grains or cereals. This component adds moisture, fiber, and a wide range of micronutrients to the diet.
Benefits of the Shunamite Diet
- Enrichment: The Shunamite diet offers unparalleled enrichment due to the wide variety of ingredients it incorporates. Rats have access to a diverse range of flavors, textures, and nutrients, stimulating their senses and encouraging natural foraging behaviors.
- Customization: The Shunamite diet allows owners to tailor the diet to their rats' individual preferences, ages, and life stages. Protein, fat, and carbohydrate levels can be adjusted to meet the specific needs of growing pups, pregnant or lactating mothers, or senior rats.
- Fiber Diversity: Shunamite diets are typically rich in diverse types of fiber, which can be harder to come by in pellet foods. Different fibers feed different beneficial microbes in the gut, promoting a healthy digestive system.
- Promotes natural behaviors: Encourages natural foraging behaviours by scattering food around their enclosure.
- Choice: Provides rats with choices and control over their environment.
Challenges of the Shunamite Diet
- Complexity: Creating a balanced Shunamite diet requires significant research, knowledge, and careful planning. Owners must understand the nutritional needs of rats and be able to calculate the appropriate ratios of protein, fat, and carbohydrates.
- Time Commitment: Preparing a Shunamite diet involves sourcing a variety of ingredients, measuring portions, and preparing fresh meals daily. This can be time-consuming, especially for owners with busy schedules.
- Risk of Imbalance: Without careful attention to detail, Shunamite diets can easily become nutritionally imbalanced, leading to deficiencies or excesses of certain nutrients. Multivitamin and calcium supplements are often necessary to ensure adequate nutrition.
- Spoilage: Fresh foods can spoil quickly, so it's important to monitor the cage and remove any uneaten portions promptly to prevent bacterial growth.
Practical Considerations for Implementing the Shunamite Diet
Base Mix Ingredients
A well-formulated base mix is essential for providing a solid nutritional foundation. Here are some ingredients to consider, based on the information provided:

- Straights Mix (Maize (whole), Barley (whole), Barley (rings), Oats (whole))
- Processed Grains (20-25% by volume):
- Pearl barley (organic)
- Rice (brown)
- Pasta (wholewheat)
- Shredded wheat
- Rice puffs
- Cornflakes
- Protein (5-10% by volume):
- Soya flakes
- Peas (flaked)
- Lentils
- Linseed
- Hemp seed
- Pumpkin seed
- Herbs and Veg (5-10% by volume):
- Carrot
- Beetroot
- Bell pepper
- Parsnip

- Nettle
- Mint
- Dandelion
- Thyme
- Rosehips
- Oregano

- Linseed
- Hemp seed
- Pumpkin seeds
- Seed mix [Panicum millet, White millet, Canary seed, Red Millet, Niger seed, Japanese millet]
- Quinoa
- Other:
- Rice/Corn Cakes - Whole Grain
- Noodles - Whole grain is better. Pasta - Whole grain is better. Try going Fish or insect based as they are kinder on the kidneys. The higher the quality the better, although this can come at expense but worth paying more for.
Fresh Meal Ideas
The fresh meal should consist of a variety of safe and nutritious options, such as:
- Vegetables: Broccoli, carrots, sweet potatoes, kale, spinach, peas, bell peppers
- Fruits: Berries, apples, bananas, melons, peaches
- Cooked Grains: Brown rice, quinoa, oats
- Other: Cooked beans, tofu, small amounts of cooked meat or eggs
Supplementation
Consult with a veterinarian or experienced rat breeder to determine the appropriate supplementation for your rats. Multivitamins and calcium supplements are often recommended to prevent deficiencies.
Monitoring and Adjustment
Closely monitor your rats' weight, body condition, and overall health. Adjust the diet as needed to maintain optimal health and address any specific needs or concerns.
Transitioning to a Shunamite Diet
If you're considering switching your rats to a Shunamite diet, do so gradually to avoid digestive upset. Start by mixing small amounts of the base mix and fresh meal into their existing food, gradually increasing the proportion over several days or weeks.
Important Considerations
- Protein and Fat Levels: Aim for a protein content of 13-14% and a fat content of 4.4-5.5% in the overall diet. Adjust these levels based on your rats' age and life stage.
- Avoid Harmful Foods: Never feed your rats foods that are toxic or difficult to digest, such as raw sweet potatoes, raw beans, chocolate, carbonated beverages, or excessive amounts of citrus fruits.
- Water: Always provide your rats with access to fresh, clean water.
Other important aspects of rat care
Enrichment
Feeding enrichment is one of the easiest and most accessible ways to increase mental stimulation for your rats, increase choice and control, and encourage natural foraging behaviours. There are many different ways to do feeding enrichment, from Shunamite diets (pioneered by Alison Campbell), scatter feeding, foraging toys, treat mixes, and fresh feeding.

Social Stress
Social stress refers to any stress that an animal experiences as part of having social relationships. The most severe social stress that a rat will experience is losing in a social encounter with another rat. It is essential as rat guardians that we understand the importance of social stress, recognise it in our own rats, and can mitigate against it.
Choice
Choice can mean many things to many people, and I think that when people say choice, they often mean a choice between available options. So, choosing between the things that they see as possible. We’re not talking about ‘heart’s desires’ - or the thing we’d do if every possible option was available - we are using a choice to mean showing preference.
The Rat’s Ancestral Diet
The rat’s ancestral diet comprises fresh, whole foods, which would have been eaten raw. However, some fresh food can be lightly cooked. A rat’s ancestral diet would not have been grain-heavy, because for most of their history rats lived independently of humans.
