Our Rats Diet

Diet in a rats short life is very, very important. Rats should be given no sugars, low salts, low or no soy and fresh grains, vegetables and fruits on a daily basis. Store bought diets (most of them) are horrible. They are full of corns, and sugars that are unnecessary fillers. You can really make the diet for your for your babies as elaborate or as simple as you wish.

I feed my rat a mix I make here. It contains everything I know a rat needs to sustain a long healthy life. The rats are offered fresh fruits and vegetables every day. I also fodder seeds for the rats I find the fresh sprouts to be much more fulfilling. My rats are given "chop" every other day that I make once a month and freeze up to have ready for them.

The diet is designed to be lower in protein (@18%), sugar and salt.  You may find some recipes call for cereal and have for years. I find almost all these cereals to contain very high levels of sugar and would recommend you stay away from these they can and do cause tumors.  You can always add a high grade fish based kibble to our mix for younger rats otherwise this diet is great for the life of our rats. Your best bet is to just purchase RRRA Dry food from our Etsy store the link is located in our navigational menu at the top of our site. If you would like to purchase a pelleted diet then Oxbow would be best. I include this in my mix and think it’s a wonderful food on its own. I suggest getting a bag of Oxbow and a bag of my food and mixing these two to last longer for both and have a bit of a mix. *Freeze any food that wont be used with in a few weeks* These ingredients are fresh made mixed with animal grade that sometimes contain weevils - to combat this freeze food - I am told they for for more fresh foods.

Rats only need about 2 tablespoon per rat per day.If you supplement with fresh items then even less required. Rats can pick out what they like first and come back for what they need later. The food may contain husks that the rat will remove and leave the shell over. These can be dumped with each new feeding. 


RRRA Dry Food:

@Two tablespoon per rat per day is a good general rule for feeding. I offer this mix as free fed here at my house and feed every other day, to ensure they are even eating those they may stash.


Ingredients: Barley, Oats, Rat Lab Block, lentils, dried peas, split peas, millet, groats, black sunflower, pasta, coconut flake, brand cereal, wheat cereal, rice cereal rainbow pasta, mealworms- treats


RRRA Mush (warm food)

RRRA Mush is a mix grains and helpful herbs for immune support. This is a very easily made food for your lil’ones that is prepared just as you would rice. One part mush to two-parts water. You can prepare on the stovetop or in a instapot- just do not over cook. Serving size is only about a tablespoon per rat. *This mix may slightly change from batch to batch as I find what may be best for rats*I suggest making up a cup of this mush then take an ice cube tray and once its prepared lay it out in the tray and freeze the tray, once frozen you can pop them out and they are serving sizes ready for 2-3 rats.  Healthy add in’s I also suggest are yogurt, raw egg (shell included), chicken (bone too!) cottage cheese, coconut oil, or yogurt.

Turmeric: is an anti-inflammatory, one of the strongest anti-inflammatory compounds in the world. Science suggests it to be up to 10 times stronger than prednisone. It also relieves pain. It's safe for rats too.

Ginger: treatment may have a protective effect against liver damage and oxidative stress in rats through free radical scavenging and anti-inflammatory activity as well as regenerating endogenous antioxidant defense system mechanisms.

Honey: Honey has antimicrobial and antioxidant properties, useful in stimulation of wounds and burns healing and gastric ulcers treatment

Chia Seed: The dietary chia seeds prevented the onset of high lipids and fats in the blood, and helped to reduce abdominal fat.

Senior Supplement

I use this blend for my older Rats(18 months plus). All thats needed is 1/2 hot water, mix and serve. However, I like to add a small amount of coconut oil and a small amount of CoQ10. I offer this 3x a week for support and daily for a rat with a tumor. A little goes a long way.

Coriolis have been found to support and enhance Natural Killer cell function, to stimulate depressed lymphocyte proliferation, and to support the healthy growth of white blood cells. Also, the research shows these constituents to be effective in supporting normal cell growth, improving cell-mediated cytotoxicity, and increasing interleukin-2 production and T-cell proliferation.*


Power Mushrooms used to treat cancer and immune deficiency. May slow growth of tumors extremely non toxic makes it very safe.


Turmeric, the bright yellow of the spice rainbow, is a powerful medicine that has long been used in the Chinese and Indian systems of medicine as an anti-inflammatory agent to treat a wide variety of conditions.


CoQ10 Many claims are made about CoQ10. It is said to help heart failure, as well as cancer, muscular dystrophy, and periodontal disease. It is also said to boost energy and speed recovery from exercise. Some people take it to help reduce the effects certain medicines can have on the heart, muscles, and other organs.


Pau d’arco is also used for cancer. Interest in this use was intensified by extensive research in the 1960s that focused on the possible anti-cancer activity of lapachol, one of the chemicals in pau d’arco. However, research studies were stopped because, at the amounts needed to be effective against cancer, pau d’arco might well be poisonous. Among other things, it can cause severe internal bleeding.


Milk thistle used for fatty liver disease and an antioxidant. Great for liver health through out life.

Grape Seed is a wonderful antioxidant 


Glucosamine is a natural chemical compound found in the body. As a supplement, glucosamine is most often used to try to ease the  joint pain caused by  arthritis.


Helpful Herbs:

You can see I use a lot of herbs in my foods for my rats. I find them to work wonderful for the little ones immune support to make them live happy and healthy. I like to save using any antibiotic’s for the rats when they really, really need them so that they will do their job properly.




Because rats can really have just about anything, rather then list what they can have here is a list of foods rats shouldnt have:

  • Bitter Almond – Bitter almonds may yield from 6 to 8% of hydrogen cyanide

  • Blue Cheese – Contains Toxic Mold (thought to be incorrect – 08/25/2013)

  • Fats (from meats) – Rats do not have gall bladders and therefore they do not have the enzymes needed to digest the fat of meat.

  • Green Bananas – Inhibits starch digestion

  • Green Potato Skin and Eyes – Contains solanine, a toxin

  • Orange Juice – May contain d-limonene which can cause kidney cancer in male rats

  • Poppy Seeds – Can cause neurological damage, or may cause death.

  • Raw Artichokes – Inhibits protein digestion

  • Raw Bulk Tofu – May contain bacteria (packaged tofu is safe)

  • Raw Dry Beans or Peanuts – Contain anti-nutrients, causes red blood cell clumping

  • Raw Onion – Can lead to anemia and an upset stomach

  • Raw Red Cabbage and Brussels Sprouts – Contains an anti-nutrient that destroys thiamin

  • Raw Sweet Potato – Contains cyanide-forming compounds

  • Rhubarb – Contains high levels of oxalates that bind up calcium.
