Can Rabbits Eat Sunflower Seeds?

Share the love of Rabbits!

Rabbits are wonderful pets who enjoy eating a variety of hays and grasses to maintain a healthy diet. Rabbits can eat sunflower seeds as an occasional treat, but it is essential to differentiate between conventional sunflower seeds and black oiled sunflower seeds, which are by far the healthier option. Commercially available seed blends and mixes are advertised as being vitamin-rich. However, many are too high in fat content to provide any real health benefits for your rabbit.

Giving your rabbit the occasional black sunflower seed treat is perfectly alright and safe and often has great benefits. Black oiled sunflower seeds can provide the right amount of fiber, fat, and protein to keep your rabbit healthy and growing.

Is There a Difference Between Traditional Sunflower Seeds and Black Oiled Sunflower Seeds?

In general, black oiled sunflower seeds are the preferred treat option for your rabbit. These seeds are higher in nutritional content and do not have much fat as traditional sunflower seeds. Plus, black oiled sunflower seeds offer plenty of other valuable minerals that can keep your rabbit healthy. Some key nutritional content in black oiled sunflower seeds includes:

  • Fat – black oiled sunflower seeds have about 28% fat content. Fat helps absorb specific vitamins like vitamins A, D, E, and K. Plus, the oils help reduce shedding and make your rabbit’s fur softer.
  • Fiber – These seeds have 25% fiber which helps keep your rabbit’s digestive tract healthy.
  • Protein – Although rabbits eat entirely plant-based matter, they need a healthy share of protein. Not only does protein help keep muscles strong, but it helps fight disease too. Black oiled sunflower seeds contain about 15% protein.
  • Vitamins and Minerals – In conjunction with the necessary fiber, fat, and protein, black oiled sunflower seeds contain high levels of B vitamins, calcium, iron, and vitamin E. All of these nutrients are necessary to fight off bacteria and infection and keep toxins out of your rabbit’s body.

Understand that any form of seeds, particularly black oiled sunflower seeds, make an excellent treat and supplemental option for your rabbit and should never be the sole source of your rabbit’s nutritional intake for the day.

Can I Give My Rabbit Seed Mixes?

Many seed mixes are readily available for rabbits. These mixes are usually called mueslix and contain a variety of seeds and grains that are held together with some sort of bonding agent, usually sugar. These hard seed mixes are advertised as an excellent way to give your rabbit a “vitamins and mineral” enriched diet, all the while providing a snack and enrichment for your rabbit.

However, despite how mueslix seed mixes are advertised, these blends are unnecessary for your rabbit. Many blends contain upwards of 4% to 5% fat content. Rabbits’ bodies are designed to run on an extremely low-fat diet, so these mixes can end up causing more harm than good. Veterinarians who treat rabbits that regularly eat seed mixes report seeing more fatty liver disease cases, and many are overweight and generally unhealthy. Although the hard mueslix mixes give your rabbit something to chew on, the same can be achieved with a simple box or basket made of untreated wood.

How Do I Maintain a Healthy Diet for my Rabbit?

Maintaining a healthy diet for your rabbit is essential to give your rabbit a long and healthy life. Your rabbit should eat a balanced diet rich in hays and grasses, with some supplemental leafy green vegetables for needed vitamins and minerals. A rabbit should always have continuous access to hay and grass, making up about 80% of its total diet. 15% of your rabbit’s diet should come from leafy vegetables, like spinach, kale, or broccoli. The remaining 5% of your rabbit’s diet can come from high-quality pellet foods that are rich in fiber.

Treats are perfectly alright for your rabbit, as long as they are given in moderation. Treats can help provide enrichment and encourage good behaviors. While black oiled sunflower seeds should certainly not be the main source of nutrition for your rabbit, the occasional seed a few times a week given as a reward is not only safe for your rabbit but will help encourage a strong bond between you and your pet.

What Are Some Safe Treat Options?

When given in moderation, treats are essential training tools that can help encourage good behavior from your rabbit. There are several healthy treat options that your rabbit will love. Some great treat ideas include:

  • Dried Pineapple – Be sure to give dried pineapple in very small doses because of the high sugar content. This treat is great when your rabbit is shedding because the enzymes in pineapple can help break down fur ingested while your rabbit is grooming.
  • Dried Flower Mix – Commercially available dried flower mixes are ideal for your rabbit because they mimic a wild rabbit’s diet. Dried flower mixes often combine dandelion, marigolds, peppermint, and nettle into a tasty and healthy blend that makes an ideal treat.
  • Herbs – Certain herbs are safe for your rabbit and make a wonderful treat. Lemongrass is a particularly fun herb because it is thick and crunchy for your rabbit to chew through. Basil (see also ‘Can Rabbits Eat Basil?‘) can also be a great treat, and many rabbits enjoy eating it directly from the plant.
  • Fresh Fruit – Some fresh fruits, when fed in small amounts, can be a wonderful treat for your rabbit. You’ll want only to use fruit as a training tool since they are high in calories and sugar. Rabbits love apples, berries (see also our article on blueberries), pears, and cherries. Your rabbit may also enjoy lemons in small amounts.

Are Certain Foods Dangerous for Rabbits?

Unfortunately, some foods are dangerous for your rabbit, which could cause your rabbit to become extremely sick or more prone to disease. While special foods are great as a treat, others could be dangerous. Some foods to stay away from for your rabbit include:

  • Fruit Pits and Seeds – Before giving your rabbit any fruits, be sure to remove the seeds altogether. Some fruits contain trace amounts of cyanide in the seeds, especially cherries (see also ‘Can Rabbits Eat Cherries?‘) and apples.
  • Avocados – Although avocados are a great snack for humans, they can be toxic for rabbits. Persin, a main component in avocados, can be toxic and make it difficult for your rabbit to breathe.
  • Raw Onions – Not only are raw onions dangerous but so are raw leeks and garlic as well. Components in these vegetables can create an oxidant that attacks the red blood cells. Prolonged diets with raw onions can lead to hemolytic anemia, which could be fatal for rabbits.
  • Rhubarb – It may be surprising to learn that rhubarb is not a safe vegetable for your rabbit. Parts of the plants are high in oxalic acid. This compound can impact your rabbit’s ability to absorb calcium in large quantities. In turn, the rabbit’s body will absorb other minerals, some of which can be dangerous. Oxalic acid toxicity leads to abdominal discomfort, diarrhea, swollen mouth, and decreased appetite.
  • Iceberg Lettuce – While leafy greens are definitely preferred for rabbits, iceberg is a lettuce rabbit owners should stay away from. A chemical called lactucarium can be harmful when ingested in large quantities. Compared to other lettuce varieties, iceberg lettuce has very limited nutritional value.
  • Mushrooms – Store-bought mushrooms that are safe for humans can be dangerous for rabbits. If the rabbit eats raw mushrooms, they could ingest even small amounts of mycotoxins which can be dangerous. These toxins lead to diarrhea, organ damage, and even neurological deficits.


Rabbits can eat plenty of different foods that can help supplement their diet and give them a tasty treat. While giving your rabbit fresh fruits and vegetables is common, many people don’t think of using sunflower seeds as a rewarding treat. Black oiled sunflower seeds are high in fiber, fat, and protein which can help keep your rabbit healthy and happy if given in small quantities. Black oiled sunflower seeds are preferred over traditional sunflower seeds. Always use treats sparingly for your rabbit and only give a few sunflower seeds a couple of times per week. Although healthy and safe for your rabbit, Sunflower seeds should never be the main staple of any rabbit diet.
