Rats are bright, restless animals who are known to like a wide range of meals. So, can rats eat granola? Is granola safe for the pet rat? Let’s find out in this article.

Granola is a breakfast and snack meal that is made up of rolled oats, nuts, honey, or other sweeteners like brown sugar, and often puffed rice, that is baked till crisp, toasted, and golden brown.

However, the mixture is mixed while baking to prevent burning and retain a loose breakfast. 

Granola contains protein, minerals, and fiber. To be specific, it might offer vitamin E, B vitamins, zinc, selenium, copper, magnesium, and iron. 

However, the nutritional profile of granola varies a lot depending on the precise ingredients used.

Alternatively, granola offers other nutrients like vitamin E, selenium, B vitamins, iron, copper, and magnesium. 


Is Granola Safe for the Pet Rat?

Even though granola contains a lot of calories and is not really healthy for the pet rat, oats, flax seeds, almonds, and chia seeds, are important ingredients in granola associated with a wide range of health benefits.

The majority of granola is high in protein and fiber, both of which help rats feel full.

Granola may contain nuts like almonds, walnuts, and cashews, including seeds like hemp, pumpkin, and sesame.

Additionally, high-fiber foods such as oats, nuts, and seeds prolong digestion time and slow down stomach emptying, which can help the pet rat feel full for longer and may help regulate their appetite.

What Cereals Can Rats Eat?

Rats have similar eating behaviors to babies in that they consume everything they see. Rats will eat anything, including jewelry and apples, but they require a responsible owner around them to prevent them from eating foods that are toxic or otherwise, harmful. 

By no means can this be considered a comprehensive list, but it might help you get started on a healthy nutritional journey with your pet rat. 

Here is a list of cereals that the pet rat can eat:


Yes, rats can eat cheerios. They can consume honey nuts, whole grains, and multiple grains of cheerios. However, cheerios should be given to the pet rat occasionally because of their high sugar content. 

Cheerios can make rats poop depending on their body system. The pet rat can also develop a stomach upset if it consumes too many cheerios. Pet rats can give out foul poop if this happens. 


Rats can eat cornflakes. Cornflakes are low in sugar and high in carbohydrates, which makes them a healthy and good snack for the pet rat. 

Rice Krispies Cereal

Rice Krispies contain additional sugar, which makes them and healthy choice of cereal for the pet rat. Rats can eat rice Krispies, but only in small amounts.

Other healthy and safe cereals that the pet rat can eat include:

  • Bran flakes
  • Weetabix
  • Fruit and fiber
  • Shredded wheat
  • Oats
  • Puffed rice

What Nuts Can Rats Eat?

All rodents enjoy nuts, including almonds, hazelnuts, walnuts, peanuts, and peanut butter. In fact, rats can get enough nutrition from almost any nut. As a result, these protein energy sources are often preferred. Here is a list of nuts that the pet rat can eat:


Rats can eat walnuts, but only in moderation. They are a good source of protein, which can help keep pet rats strong and healthy as they age.

Additionally, walnuts contain healthy vitamins and minerals that the pet rat may need for optimum health, including vitamins E and B6, folic acid, and phosphorus.

Walnuts also contain antioxidants, which are essential for preventing diseases like cancer. Rats can rely on the energy boost that walnuts provide to actively get through the day.


Rats can eat hazelnuts as a treat. The pet rat can only consume hazelnuts in moderation because of their high salt content.

It goes without saying that rats enjoy eating nuts, but they should not be permitted to eat too many hazelnuts at a time. 

Brazil Nuts

Yes, rats can eat Brazil nuts. Brazil nuts are One of the biggest nuts on the highest nutritional source of selenium. The health of the immune system and the function of the thyroid gland depends on the mineral selenium. It also functions well as an antioxidant.

Rats can eat Brazil nuts unsalted and raw. They are large nuts and if you feed them often, a sixth to an eighth of a nut is enough. 

Brazil nuts are a good source of vitamin E, thiamine, copper, iron, calcium, and zinc, in addition to selenium.

Pine Nuts

Pine nuts are smaller than any other nuts, and are the ideal size for rats to eat one or two as a treat.

In addition to other vitamins and minerals, pine nuts are a rich source of antioxidants, vitamin K, iron, zinc, and copper. However, they do have a tendency to cost a little more than most other nuts.

Cashew Nuts

Yes, rats can eat cashew nuts. The cashew nut is another medium-sized nut that easily separates into two halves. It boasts a high mineral concentration, including selenium, iron, copper, and zinc.

Like all nuts, cashew nuts are also high in protein, polyphenols, antioxidants, and omega-6 fats.

Cashews are regarded as having anti-cancer, anti-anemia, and anti-infection properties.

You should restrict the rat’s consumption if it is old or exhibiting symptoms of kidney problems because they are high in phosphorus. If not, feed the rat around half of a nut once or twice a week, rotating it with other nuts.


Bottom Line

Rats are prone to gain weight easily when they consume foods high in fat and sugar. Even though rats can eat granola, it is still not the best option for them, and there are still so many varieties of human food to choose from for the rat.
