Can Rats Eat Cashews? [Is It Healthy?]

Can Rats Eat Cashews

Cashews are a type of nut that comes from the cashew tree, which is native to Brazil. They are widely popular as a snack and ingredient in many cuisines around the world.

Cashews are kidney-shaped nuts with a sweet and buttery flavor. They are often used in cooking, baking, or simply eaten as a snack.

But can rats eat them too?

Yes, rats can indeed eat cashews, but it should be given to rats in small, infrequent amounts as a treat, and they should be plain, unsalted, and unroasted. Rats can enjoy a variety of foods, but their primary diet should consist of specially formulated rat food to ensure they receive the necessary nutrients for their health.

So, should you feed cashews to your pet rats?

Let’s find out!

Can Rats Eat Cashews?

Cashews are okay for rats to eat, but they should only have a tiny piece once in a while as a treat. Cashews are pretty high in fat, and too much fat isn’t good for little rat tummies. If rats eat too many cashews, they might get a tummy ache or become overweight, just like people can if they eat too many snacks.

So, it’s best to give your pet rat a small piece of cashew now and then, like a special treat, but not as their main food.

Rats have their own special rat food that’s much better for their daily diet. And don’t forget, always make sure the cashews are unsalted, as salt isn’t good for rats either.

Just remember, treats are nice, but too many treats can be a little like eating too much candy for us – not the healthiest choice.

Rats are pretty small animals, and when it comes to cashews, you should give them only a very tiny amount.

You can think of it like giving them just one or two small pieces of cashew. Rats are quite sensitive to the fat content in nuts like cashews, so it’s essential to be careful not to overdo it.

It’s best to use cashews as an occasional treat, not a regular part of their diet. Most of their food should be their specially designed rat food, which has all the right nutrients they need.

So, to sum it up, a little piece of cashew now and then is okay, but not too much, to keep your rat happy and healthy.

A typical serving of cashew (28-gram) offers:

  • Calories: 157 kcal
  • Protein: 5 grams
  • Carbohydrates: 9 grams
  • Dietary Fiber: 1 gram
  • Sugars: 2 grams
  • Fat: 12 grams

Other health benefits of cashew may include:

Cashews provide a decent amount of protein, which is important for growth and overall health in rats.

While the high fat content can be a concern in excess, the fats in cashews include heart-healthy monounsaturated fats and polyunsaturated fats that are beneficial for energy and cell function.

Cashews are a good source of essential minerals such as magnesium, phosphorus, and zinc, which are vital for maintaining bone health and overall well-being.

Cashews contain antioxidants like vitamin E, which can help protect cells from damage caused by free radicals.

Potential Risks of Overfeeding Cashews to Rats

Risks of Overfeeding Cashews to Rats

While cashew is highly nutritious, they can be bad for your rats too. Overfeeding cashews or any high-fat treats to rats can pose several risks to their health.

Here are some risks of giving too many cashews:


Cashews are rich in fats, and excessive consumption can lead to weight gain.

Just like in humans, obesity in rats can lead to various health issues, including heart problems, diabetes, and reduced lifespan.

Digestive Problems

Rats may have difficulty digesting a high-fat diet, which can result in diarrhea, upset stomach, or other digestive issues.


High-fat foods like cashews can be dehydrating for rats. This can lead to increased thirst and more frequent urination.

Kidney and Liver Issues

The high fat content can put extra strain on a rat’s kidneys and liver, potentially leading to long-term health problems.

Dental Problems

Cashews and similar hard treats can wear down your rat’s teeth excessively if fed in excess, leading to dental issues.

Thus, it’s crucial to offer treats like cashews sparingly and make sure they make up only a tiny portion of their diet.

Can Rats Eat Salted or Roasted Cashew?

It’s not a good idea to give rats salted or roasted cashews.

Here’s why,

Rats are very sensitive to salt. Too much salt can harm their health and lead to problems like dehydration or kidney issues. Salted cashews have added salt, which is not safe for rats.

So, it’s best to avoid giving them salted cashews.

On the other hand, roasted cashews are cooked with heat, and sometimes they have added oil, which makes them higher in fat.

While a tiny piece of roasted cashew once in a while probably won’t hurt your rat, it’s still better to give them raw, unsalted cashews or other healthy treats that are safer for their little tummies.

So, it’s always best to stick with unsalted, raw cashews or other rat-friendly treats in moderation.

Can Rats Eat Cashew Shell?

No, rats should not eat cashew shells. Cashew shells can be toxic and even harmful to rats.

The shells contain a substance called urushiol, which is a natural chemical that can cause skin rashes and other health problems. This substance can be especially harmful if ingested.

To keep your pet rat safe and healthy, always make sure that you only give them the nut part of the cashew without the shell.

The nut itself can be an occasional treat, as long as it’s unsalted and in moderation, but it’s important to avoid the shell altogether.

Other Treat Options for Rats

There are many safe and healthy treat options for pet rats. Here are some great alternatives to cashews:

  • Fresh Fruits: Rats love fresh fruits like apples, pears, bananas, and berries. Just be sure to cut them into small pieces, and remove any seeds or pits because some fruit seeds can be harmful.
  • Fresh Vegetables: Rats also enjoy veggies like carrots, broccoli, peas, and sweet potatoes. These provide essential vitamins and minerals.
  • Unsalted Nuts: Besides cashews, you can offer unsalted almonds, walnuts, or hazelnuts in moderation.
  • Whole Grains: Rats can nibble on small amounts of cooked whole grains like rice or pasta. These can be great as occasional treats.
  • Yogurt Drops: Special yogurt treats made for rats can be a fun and safe option. They come in various flavors and can be a good source of calcium.
  • Herbs: Fresh herbs like basil, cilantro, and parsley can add variety to their diet and provide some essential nutrients.
  • Cheese: Small amounts of unsweetened, plain, or low-fat cheese can be an occasional treat.
  • Mealworms: Dried mealworms or small bits of cooked chicken or scrambled eggs can be a source of extra protein.

Remember that treats should only make up a small portion of your rat’s diet. The majority of their food should be a well-balanced rat pellet or block.

Always offer fresh water, and monitor your rat’s reactions to new foods to ensure they tolerate them well.

Providing a variety of treats can keep your pet rat happy and healthy.

Final Thoughts

To sum up, rats can eat cashews, but there are some important considerations to keep in mind.

Cashews should only be given as an occasional treat in very small portions.

While cashews do offer some nutritional benefits, particularly in terms of protein, healthy fats, and essential minerals, their high fat content can be a concern if overfed.

To maintain your pet rat’s health, it’s crucial to prioritize their regular rat food, which is specially formulated to meet their nutritional needs.

Always choose plain, unsalted, and unroasted cashews and ensure they are fresh and cut into small, manageable pieces to avoid choking hazards.
