Can Rabbits Eat Acorns?

Rabbits are herbivores, so they should not eat acorns.

Acorns can be toxic to rabbits and cause them to develop potentially fatal liver disease. Acorns also contain a high-fat content that is unhealthy for rabbits.

Rabbits need more fiber in their diet than just grass and hay, but they cannot digest the high-fiber foods like vegetables or grains on their own because they lack the enzymes necessary to break down these substances.

A rabbit’s digestive system does not have a cecum or appendix like humans do, which makes it difficult for the rabbit to get nutrients from plants other than grasses and weeds. So while some people think it’s ok for a rabbit to eat an occasional acorn here and there, the reality is that acorns are not good for rabbits.

What Are Acorns And What Do They Look Like?

Acorns are the fruit of oak trees. They are small and round, with a hard shell. The inside of an acorn is filled with a soft, edible kernel.

What are some health risks related to eating acorns?

One of the biggest concerns is that acorns are naturally high in tannins. Tannins can cause gastrointestinal upset when they are eaten. If you suspect that your rabbit has consumed any amount of acorn, it is important to watch for signs of an upset stomach. Other reported health concerns from eating acorns include diarrhea, vomiting, and general malaise.

What To Do If Your Rabbit Eats An Acorn?

Rabbits that eat acorns can develop a condition called acorn poisoning. This is caused by the tannins found in acorns. Tannins are natural chemicals that can cause liver damage and other health problems in rabbits. Eating just a small amount of acorn could cause rabbits to become extremely ill and, in some cases, may even prove fatal.

A rabbit can consume enough tannins from as little as 10g of raw acorns to cause harm. Acorns also contain very low amounts of protein and fiber so they aren’t beneficial for rabbits to eat at all. They should not be fed to rabbits as a treat and never in large enough amounts to cause poisoning.

A single feeding of acorns will not harm your rabbit, but if they eat them regularly, you may find that their poo becomes very loose and smelly.

If your rabbit eats acorns or other nuts, it’s best to monitor them for any signs of illness. Signs that your rabbit may be suffering from acorn poisoning include:

  • Diarrhoea
  • Lack of appetite
  • Vomiting

Symptoms can last up to a week, but you’ll likely see improvement in the first 24 hours after the acorns have been eaten.

If your rabbit shows any of these signs, take them to a vet as soon as possible for treatment. If left untreated, potentially fatal liver damage could occur and your rabbit may need supportive care including fluid therapy and even blood transfusions.

How To Prevent Your Rabbit From Eating Acorns?

There are a few things you can do to prevent your rabbit from eating acorns.

  1. First, try to keep your yard cleaned up and free of acorns.
  2. Second, make sure your rabbit has a healthy diet and is not missing any essential nutrients.
  3. Third, provide your rabbit with plenty of distractions to keep them occupied.
  4. And finally, if all else fails, you can always have your rabbit vaccinated against oak poisoning.

Vaccines are available for both domestic and wild rabbits. If you have indoor/outdoor rabbits, be sure to talk with your veterinarian about vaccinating them against oak poisoning.

Even if you don’t live where acorns are abundant, it is best to make sure your rabbit is protected from any unknown dangers. Prevention is the best cure.

The most important thing you can do to protect your rabbit from acorns is to make sure they are not missing any essential nutrients in their diet.

Rabbits should always have a healthy and nutritious diet full of hay, vegetables, and freshwater. Make sure they get plenty of exercises so that they don’t become obese or overweight.

Rabbits that are missing any essential nutrients may seek out other food sources, like acorns. They might also turn to eat their droppings, which can lead to intestinal problems and even death in rare cases.

If your rabbit seems interested in acorns (or anything else for that matter), make sure to discourage this behavior. If you find your rabbit eating acorns, immediately try to distract them to keep them occupied.

Water bottles filled with hay, fresh vegetables, and other distractions can help keep your rabbit busy until the acorn craving passes.

A Healthy Alternative To Acorn As Treats?

Oak trees produce acorns, which are a healthy source of nutrients for wildlife. However, acorns are not a healthy food choice for rabbits. While they may enjoy nibbling on the occasional acorn, acorns contain tannins that can make them sick.

There are many healthy alternatives to acorns that rabbits can enjoy as treats instead. Some good options include fresh vegetables, chopped fruit, and specially made rabbit treats.


While acorns are not toxic to rabbits, they should not be a significant part of their diet. Acorns are high in tannins which can cause gastrointestinal problems for rabbits.

A small amount of acorns as an occasional treat is okay, but make sure that the majority of your rabbit’s diet consists of hay, fresh vegetables, and a small number of pellets specifically designed for rabbits.
