Can Rats Have Peanut Butter?


Although peanut butter is rich in protein, which is fantastic, it also includes approximately 50% fat, which can have a long-term detrimental impact on your pet rat’s health if consumed in excess—as they would if left to their own ways.

As a result, peanut butter is a nice treat for your pet rat occasionally in moderation, but it should not replace a varied, balanced diet.

What to Consider When Feeding Rats Peanut Butter


Here are some things you must take into account before feeding rats peanut butter:

Rats are Omnivorous

First, it’s important to note that rats are omnivores, meaning that they eat a wide variety of foods, including both plants and animals. This means that, theoretically, rats could eat peanut butter without any problems.

However, it is important to consider the specific nutritional needs of rats and whether or not peanut butter would provide them with the necessary nutrients and vitamins they need to stay healthy.

High in Fat


One concern is that peanut butter is high in fat. Rats, like all animals, need a certain amount of fat in their diet to stay healthy, but too much can lead to obesity and other health problems.

Additionally, many commercial brands of peanut butter contain added salt and sugar, which can be harmful to rats in large amounts.

Because of these concerns, it is best to feed rats peanut butter in moderation and to choose a brand that is made with natural ingredients and has minimal added salt and sugar.


Another important consideration is that rats are prone to a condition called obesity. They can consume a lot of food because they have a very fast metabolism, so providing them with a lot of high-calorie foods can be harmful to their health.

Also, peanut butter can be a choking hazard for rats and can potentially block their airways. So the peanut butter should be served in small amounts and in a smooth paste consistency to avoid any risks.

Balanced Diet

In terms of nutritional value, peanut butter is a good source of protein, healthy fats, and a variety of vitamins and minerals.

However, it is important to note that rats also need a balanced diet that includes a variety of fruits and vegetables, as well as a source of protein from animal sources.

Do Rats Like Peanut Butter?


Rats are known to be opportunistic eaters, which means that they will eat a wide variety of foods and often eat whatever is available to them.

This means that, in theory, rats should like peanut butter just as much as they like other foods. However, just because a rat will eat something, doesn’t necessarily mean that it likes it.

Many rats do enjoy eating peanut butter, but others may not be particularly fond of it.

Factors that can influence a rat’s preference for peanut butter include their individual taste preferences, as well as the texture, smell, and other qualities of the peanut butter itself.

One reason that rats may like peanut butter is that it is a high-energy food that is rich in fats and protein. Rats have a fast metabolism and need a lot of energy to stay active, so peanut butter can be a good source of fuel for them.

Additionally, the high-fat content of peanut butter can be appealing to rats, as they need a certain amount of fat in their diet to stay healthy.

Another reason that rats may like peanut butter is that it has a strong, distinctive smell and taste that can be appealing to them.

Rats have a keen sense of smell, and they use it to locate and identify different types of food. Peanut butter has a strong, nutty smell and taste that can be attractive to rats, even if they have never tasted it before.

It’s difficult to make generalizations about whether rats like peanut butter or not, as every rat is an individual with its own personality and preferences.

It can be useful to offer a small amount of peanut butter to your rat as a treat and observe its reaction, this can help you get a sense of whether or not your rat likes it. 

Also, providing a variety of food options for your rat is important, as it can help ensure that your rat is getting a well-balanced diet and will also give them the opportunity to try new things and explore different tastes and textures.

Can Rats Eat Peanut Butter Shells?


Rats can technically eat peanut butter shells, but it is not recommended. Peanut shells, like any kind of nutshell, are hard and indigestible, and they can cause blockages in their digestive tracts and cause gastrointestinal issues.

Ingesting large amounts of shells can also lead to blockages in the intestines and even death.

Peanut shells also have a high-fiber content, which can cause digestive upset and gas in rats. Additionally, feeding your rat peanut shells could also lead to an unhealthy obsession with foraging for shells instead of eating a balanced diet.

What Other Foods Can Rats Not Resist


There are certain types of food that rats seem to particularly enjoy and find irresistible. Understanding the types of food that rats like to eat can help you ensure that your pet rat is getting the nutrients it needs to stay healthy and happy.

Fruits and Vegetables

Rats are known to enjoy a wide variety of fruits and vegetables. Some popular choices include apples, bananas, berries, carrots, broccoli, and leafy greens such as spinach or lettuce.

These foods are high in essential vitamins and minerals, such as vitamin C, vitamin A, and folate, that rats need for optimal health.

It’s important to note that rats can’t digest certain fruits and vegetables very well, like raw potatoes or uncooked beans, which could cause health problems.

Protein Sources

Rats require protein in their diet to support growth, repair, and maintenance of their body. Good sources of protein include cooked meat, such as chicken, turkey, or beef, cooked eggs, and high-quality, low-fat cat or dog food.

Also, many rats enjoy insects and worms as part of their diet. It’s best to avoid processed meats, like bacon and sausages, which are high in salt and other additives that can be harmful to rats.

Whole Grains


Rats require carbohydrates to provide energy. Whole grains like oats, wheat, barley and corn are a good source of carbohydrates for rats.

Whole wheat bread and pasta, quinoa and brown rice are also great options. Avoid refined grains, like white bread and white pasta, which have had many of the nutrients removed.

Seeds and Nuts

Rats enjoy a variety of seeds and nuts as treats, such as sunflower seeds, pumpkin seeds, and almonds. These foods are high in healthy fats and protein and can be a good source of energy for rats.

However, it is important to note that many nuts and seeds are high in fat and should be offered in moderation as part of a balanced diet.


Rats also enjoy a variety of treats that can be used to provide a source of variety and excitement in their diet. Treats like yogurt drops, dried fruit, and cereal can be great choices, but it is important to avoid high-sugar treats.
