Can Rabbits Eat Macadamia Nuts?

While macadamia nuts are not poisonous to rabbits, you should never intentionally feed them to your rabbits because they are high in fat and starch.

100 grams of macadamia nuts contains 76 grams of fat and 1.05 grams of starch, while rabbits should limit themselves to 0–138 grams of starch, meaning rabbits can be fine with or without any starch in their diet. Rabbits should also limit themselves to 20-50 grams of fat per day.

Feeding fatty and starchy foods like macadamia nuts to your rabbits would do more harm than good.

You should focus on feeding your rabbits high-quality hay instead.

If you notice any changes in your rabbit’s stool, both in size and consistency, immediately bring your rabbit to a veterinarian.

Now that I’ve given you the gist of the article, read on as I explain in more detail why rabbits can’t eat macadamia nuts:

Risk of overfeeding macadamia nuts to rabbits.

Fatty and starchy foods like macadamia nuts should not be fed to rabbits intentionally.

They carry certain risks when fed in large amounts because rabbits’ digestive systems are not really designed to digest large amounts of food like macadamia nuts.

Here are some of the risks associated with feeding your rabbits large amounts of macadamia nuts:

Fatty liver disease

Macadamia nuts are high in fat, feeding your rabbits macadamia nuts long-term could lead to hepatic lipidosis, or fatty liver disease.

Rabbits’ diets should only consist of less than 3% fat, while macadamia nuts are high in fat.

Here are the signs that your rabbit might be suffering from fatty liver disease caused by excess fat:

  • Loss of appetite (anorexia) – may be sudden or gradual.
  • Weight loss
  • Decline in number and size of droppings (feces)
  • Dehydration
  • Depression and lethargy


Diarrhea in rabbits is often caused by the wrong diet or when their diet is changed too fast. 

Feeding your rabbit large amounts of macadamia nuts would check those two boxes I mentioned.

Gastrointestinal Stasis

Gastrointestinal stasis is also possible when a rabbit is fed large amounts of macadamia nuts, which are high in fat.

GI stasis mainly happens when a rabbit is fed a low-fiber diet.

GI stasis happens when the balance of bacteria in your rabbit’s gut is disrupted.

This disruption would cause painful gas that would eventually lead to organ failure and death if not treated immediately.

The signs of GI stasis are:

  • Depressed
  • Hunched posture
  • Bruxism
  • Decreased appetite/anorexia

If you notice any of these signs, immediately bring your rabbit to a veterinarian.

Uneaten cecotropes

Soft uneaten cecotropes are also possible when rabbits are eating large amounts of macadamia nuts instead of hay.

This could lead to softer cecotropes due to the lack of fiber in your rabbit’s diet.


Obesity in rabbits is also possible when fed large amounts of starchy food.

Rabbits that are confined in cages all day without exercise and fed large amounts of a high-carb, low-fiber diet are the most susceptible to obesity.

Healthy alternative to macadamia nuts as treats.

If you are planning on giving your rabbits macadamia nuts as treats, these alternatives are much healthier.

Here are some alternatives that you can give to your rabbits one to two times per week as a treat:

FAQ (Frequently Asked Questions)

Should you panic if your rabbit eats a little bit of macadamia nuts?

While macadamia nuts are not recommended for rabbits, they’re still not toxic.

It’s just that macadamia nuts are too high in fat and starch, both of which are not digested well by rabbits.

If you are worried, just feed them a lot of hay.

The extra fiber would likely fix the problem on its own.

What to do if your rabbit ate macadamia nuts?

Observe their behavior and poop for any changes.

You should also feed them a lot of hay.

The extra fiber would help balance their gut flora.

If you notice any changes in their poop or behavior, consult a veterinarian immediately.


Macadamia nuts should never be fed to rabbits intentionally because they are high in fat and starch.

Also, rabbits that are fed large amounts of fatty and starchy foods like macadamia nuts could experience digestive distress like diarrhea, fatty liver disease, and GI stasis.

It could also lead to obesity, especially in rabbits who are confined in small cages all day without access to regular exercise.

If your rabbit is exhibiting signs of digestive distress, immediately bring them to a veterinarian.
