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.  I breed my own meal worms for the rats to munch on. The rats also get a lil'bit of our dinner each night I think its the highlight of their day, you can catch them all lined up at the playpen waiting for their share each night. 

Raining Rats typical daily feed day:

AM: Couple pieces of Oxbow Regal Rat

PM: Daily diet/Fresh Veggies and some fruit

Always available in hopper: Halen Tek 18% lab block

Every other day chop and sprouts


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.  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*


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, parrot pellet. brand cereal, wheat cereal, rice cereal  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. 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.


Ingredients: Barley, oats, brown and black rice, couscous, quinoa, wheat germ, green split peas, yellow split peas, lentils, coconut, raisins, cumin, green mush powder, grape seed extract, chia seed, flaxseed, blk seed, orzo, muesli, dried fruits/veggies, melatonin, sage, cloves, teas, bay leaf, flaxseed, chickweed, Dill, milk thistle, garlic, oregano, basil, rosemary, flowers, turmeric, cinnamon, fig, goji berries, *mug bean

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.
