The pet food industry has undergone an amazing boom and changes in the last decade. We have learned that the industrial, over-processed, pet foods that we have simply picked off the shelves because they caught our eyes are maybe not the best food for our pet rats and other pets. People are trying to look at ingredients and %s and find the best possible food. But what foods are actually good for our pet rats? What is true nutrition and what is filler?

Pet rats will flourish on a simple kibble or block diet that should ALWAYS be available to nibble on.  Due to their high metabolism rats should be able to nibble every few hours.  I DO recommend adding twice a week a mix of other healthy foods, just enough that they will finish them in one night, I will be adding varied recipes for these soon. And I do feed my rats some of my healthy food scraps and occasional junk food(like once a month they will get part of a cookie).

Do NOT buy any foods that have seed mixes or other added ingredients to make the bags seem more appealing. NEVER feed cat or dog food as a staple diet. The ingredients and %s are not made for rodents.  These foods are unbalanced and may include some not so healthy ingredients.

Growing rats need approximately 18-23% protein  5-10%fat   3-7% fiber

Adult rats 10-18% protein   4-6% fat   3-7% fiber

Simplified, What I recommend:

The brand of diet that I use is Mazuri Rodent Breeder. I have only found it in 50 lb. bags. Most people don’t have enough rats to eat this much food before it goes bad.

The brand of diet that I recommend to most of my pet buyers is Adult Rat Oxbow. It is readily found in most pet stores and has a good balance of protein, and ingredients. It is also low in fillers (foods that cannot be digested by rats), however does need a little added protein. Here are some of the available rat foods, their percentages of protein, fat, and fiber. I have also listed the 5 top ingredients, which are the main ingredients of the food. Foods in italic are generally considered filler with little nutrition.
