What Rabbits Really Eat
Rabbits have a very complex digestive system, and making sure your rabbit is eating a proper diet is very important to your rabbit’s wellbeing. In fact, improper eating habits are closely associated with the most dangerous and common health problems in rabbits. Rabbit.org explains that rabbits, like many animals, naturally gravitate towards high calorie foods that are high in sugar or starch. Foods high in starch and sugars create a change in the pH of the cecum and eventually results in dangerous GI disease. A healthy diet consists of a variety of grass hay (80%), fresh vegetables (10%-15%), and good quality food pellets (5%-10%), all of which need to be given in proper proportions. Anything besides that should be considered a treat and given in limited quantities. Clean, fresh water needs to be available at all times, which can be dispensed in either a bottle or ceramic bowl depending on your rabbit’s preference.
The most important component of your rabbit’s diet is grass hay, rich in Vitamin A and D as well as calcium, protein and other nutrients. A diet of 80% hay can also act as preventative health care for your rabbit, promoting healthy teeth and a healthy digestive tract. Rabbits’ teeth continually grow approximately 12 centimeters a year, even their back ones. Overgrown teeth can cause many issues including eye problems, but the side-to-side motion from eating hay naturally grinds teeth from getting too long. Hay is also essential to a rabbit’s health by providing roughage which reduces the danger of hairballs. Despite regular grooming, rabbits lack the ability to cough up hairballs. Rabbits need to constantly snack on hay throughout the day to keep things moving inside and help prevent blockages which can often be fatal. Apple tree twigs also provide good roughage but should be given as a treat and not a main food source.
You want to provide your rabbit with grass hay such as Timothy, Orchard, or Brome, and be sure to avoid legume hay like alfalfa or clover for adult rabbits. Alfalfa is like rabbit candy and contains too many calories, can cause bladder stones, and put a strain on the kidneys for an adult. However, young rabbits (under a year old) need additional energy and nutrients and should get alfalfa mixed in with their hay.
Offer your rabbit fresh hay every day, multiple times a day. Rabbit.org also recommends varying the type of grass hay or mixing grass hays together. A diversity of hay provides rabbits to small changes in smell and texture, resulting in good, consistent eaters. Different rabbits can like different kinds of hay, be sure to take notice of your own rabbit’s preferences. Bagged hay is readily available at pet stores; however, you will go through a lot of hay in just a day or two. A more affordable option is to go to your local farm feed store and purchase a bale of horse hay (not straw) and store it upright in a large trash can. This will last a long time and save you money in the long run. Hay will last up to a year without losing any significant amount of nutrition as long as it is kept dry and out of the sun. Wet hay will mold which is bad news for your bunny and sunlight decreases the nutritional value.
Pellet Food (5%-10%)
There are many brands and types of feed for rabbits, but the best brand for your rabbit is Oxbow, formulated with the proper vitamins and minerals for your new friend. High quality pellets are a minimum of 18% fiber and less than 2% fat. Look for food that is comprised of plain green pellets and avoid any added colorful pieces. These foods are intended to attract the human buyer, but unfortunately the added pieces are not in the best interest of your rabbit’s health. Food that includes nuts, seeds, or other “treats” and colorful pieces or that use the term “gourmet” are usually very rich and high in fat which can cause serious health issues for your rabbit and should be avoided. Variety in your rabbits diet should be provided by fresh vegetables and not extra ingredients in pellet food.
Besides high quality pellets, make sure not to overfeed your rabbit. Rabbits can easily become overweight if not fed the proper amount, which also leads to many health problems. For an adult rabbit, it is best to feed ¼ to ½ cup of feed per day. Rabbits under a year should be offered more since they are growing, but be sure they are eating a young rabbit formula rich in nutrients. You also do not want to buy a large amount of pellet food at once. Unlike hay, pellets will become spoiled after about 6 weeks.
Fresh Vegetables and Fruit (10%-15%)
Along with pellets and hay, your rabbit needs fresh vegetables and fruit daily. Fresh foods are an important part of your rabbit’s diet and they provide additional nutrients as well as different textures and tastes, which are enriching for your friend as well. Fresh foods are also more hydrating, which is good for kidney and bladder function. If you collect wild foods such as dandelion greens, make sure they are from a pesticide-free area and never give your rabbit grass cut by a lawnmower because chopped grass will ferment. Also try to purchase organic produce if possible, but regardless of the source, Rabbit.org advises that all fresh foods should be washed or scrubbed (as is the case with hard vegetables) before being given to your rabbit.
Suggested daily amount of fresh food is 2 cups per 4-6 Ibs of your rabbit’s body weight. Introduce one new food every three days and keep a watch on the stools. Even root vegetables and fruits with high levels of sugars and starch could become a problem if fed in excess, and should only be fed as a very small part of the diet. Foods that are notorious for causing GI problems for rabbits are grains of any kind, legumes (beans, peas, etc), nuts and seeds, popcorn, garlic, potatoes, rhubarb, chocolate and other “human treats.” Also avoid foods in the onion family such as leeks, chives and onions because eating these foods could cause blood abnormalities. Watch your rabbit for weight loss, soft stool, or any other signs of trouble and consult your veterinarian immediately if there are problems. It’s also a good idea to find a vet familiar with rabbits and have regular checkups, which can also help prevent obesity.
Feed your rabbit at least 3 types of leafy greens a day, and mix it up by rotating between different greens your rabbit will enjoy. Rabbits have a higher risk of calcium problems, so give your rabbit smaller amounts of high calcium greens. Reference the list below to help distinguish between low calcium and high calcium greens. Never feed your rabbit iceberg lettuce.
Low Calcium Greens (pick 2 out of 3)
Kale (all types)
Mint (any variety)
Basil (any variety)
High Calcium Greens (pick 1 out of 3)
Sprouts (from 1 to 6 days after sprouting)
Non-Leafy Vegetables (A recommended daily amount to feed your rabbit is about 1 tablespoon per 2 lbs of body weight).
Edible flowers (roses, nasturtiums, pansies, hibiscus)
Fruits can also be fed in small amounts and make great training treats! Feeding treats by hand is also a great way to develop a close bond with your bunny. Rabbit.org recommends feeding about 1 teaspoon of fruit per 2 lbs of body weight per day. Remember to feed your rabbit a lesser amount of dried fruits which are about 3 times as concentrated as fresh fruit. Usually it is more nutritious to leave the skin on the fruit. However, remove the skin if you are concerned about chemicals.
Cherries (without pits)
Berries (any type, uncooked)
Plum (without the pits)
Pineapple (remove skin)
Banana (remove peel; no more than about 2 1/8 inch slices a day for a 5 lb rabbit)
