Rabbits
are eating machines! Thanks to their unique physiology, these
remarkable small herbivores must consume a near-constant intake of
fiber to keep their specialized digestive tracts running smoothly. Just
because rabbits are herbivores, however, doesn’t mean they can eat all
varieties of greens, veggies, and fruits. Their unique dietary
requirements also make many “human treats” (and even some marketed for
rabbits) inappropriate as they can lead to serious health
concerns if consumed.
The list below
outlines the most common foods that should never be fed to
rabbits, but it is always best to check with your favorite
rabbit-savvy veterinarian before introducing any new food to your rabbit’s
diet. Similarly, if your rabbit ever ingests one of the items listed
below (regardless of quantity), call your veterinarian
immediately.
- Avocados
- Chocolate
- Fruit seeds/pits
- Raw onions, leeks, garlic
- Meat, eggs, dairy
- Broad beans and kidney beans
- Rhubarb
- Iceberg lettuce
- Mushrooms
- House plants
- Processed foods (bread, pasta, cookies, crackers,
chips, etc.)
- Raw potatoes
Avocados
Though an
excellent, healthy snack for humans, avocados contain a compound
called persin which can be dangerously toxic to
rabbits. This compound is found in all parts of the avocado: skin,
pit, leaves, and flesh. If a rabbit consumes toxic levels
of persin, it can cause behavioral abnormalities and difficulty
breathing, and, if not properly treated, can lead to congestive
heart failure (fluid around the heart) which can prove fatal.
Chocolate
As is the case
with many other members of the animal kingdom, chocolate is incredibly
toxic to rabbits. This favorite human treat contains theobromine and
caffeine, both of which can be very harmful to our furry friends. The darker
the chocolate, the higher the risk of toxicity. Signs of chocolate toxicity
include diarrhea, restlessness or hyperactivity, trembling,
panting, squirming or difficulty getting comfortable, tachycardia
(elevated heart rate), and hyperthermia (elevated temperature). Without
swift treatment, chocolate toxicity can prove fatal.
Fruit Seeds/Pits
Take care to remove
all seeds and pits before offering fruit to your bunny. While
feeding small amounts of many fruits’
flesh is perfectly safe, the seeds and pits from many
fruit varieties contain trace amounts of cyanide. Apples and
pears are the most notorious examples, but the pits from apricots, peaches,
plums, and mangos also contain cyanide, as do cherry pits. While
the amount of cyanide contained in fruit seeds and pits is generally
scant, it is best to avoid feeding them to rabbits altogether.
Raw Onions, Leeks, Garlic
Raw allium vegetables,
such as onions, leeks, and garlic, contain an oxidant called n-propyl disulfide
that likes to attach itself to red blood cells. While humans are relatively
unaffected by this oxidant, rabbits are more susceptible to “oxidative
damage.” As the body tries to rid the blood of the unrecognized oxidant,
it will destroy the red blood cells in the process. This leads to a condition
called hemolytic anemia which can be fatal if not treated promptly and
aggressively. Symptoms of hemolytic anemia include pale gums, ataxia
(stumbling), weakness, disinterest in food or water, and lethargy.
Meat, Eggs, Dairy
Though this likely
will not come as a surprise, it is worth mentioning that rabbits, as
herbivores, should never be offered meat, eggs, or dairy. Unlike
carnivores or omnivores, whose digestive systems are designed to properly
digest animal protein, rabbits’ sensitive gastrointestinal tracts are
specifically equipped to break down low-fat, high-fiber
vegetation.
Though most rabbits
would turn their nose up at a piece of steak, they do have a notorious sweet
tooth, and often find yogurt drops (or other dairy products) enticing. While it
may seem harmless to offer a sweet, dairy-rich treat from time-to-time, it can
lead to gastrointestinal upset and substantially increase the risk of
obesity or dysbiosis (disruption of the microbiome). For these reasons, it
is best to avoid feeding rabbits any product containing meat, eggs, dairy, or
other animal-derived proteins.
Broad Beans and Kidney Beans
Broad beans (otherwise
known as fava beans) and kidney beans are very high in carbohydrates and can
throw off your rabbit’s delicate gastrointestinal system, resulting in
soft stools or diarrhea, abdominal discomfort, bloating, and
even disruption of the gastrointestinal GI) bacterial flora (Dysbiosis).
They also contain a high level of phosphorus and calcium and tend to be quite
acidic, making them unsuitable to rabbit’s unique nutritional
requirements.
Rhubarb
This tart
vegetable contains an impressive concentration of a compound
called oxalic acid in all parts of the plant. Though oxalic acid is
not toxic if consumed in small quantities, if fed in excess, it
can interfere with calcium absorption and lead to other unpleasant toxic
effects. Rabbits experiencing oxalic acid toxicity can experience a
swollen, painful mouth, decreased appetite, bloating
and abdominal discomfort, diarrhea, and lethargy.
Iceberg Lettuce
While there
are several varieties of dark, leafy lettuces (like romaine and green
leaf) that make wonderful staples in a well-balanced rabbit diet, light-colored
lettuces, like iceberg, contain a chemical called lactucarium that can be
harmful to rabbits if ingested in large quantities. Additionally, iceberg
lettuce is anything but nutrient-dense and will add no nutritional value
to a rabbit’s diet. It’s best to be avoided.
Mushrooms
When people think of
toxic mushrooms, they often envision the toadstools that mysteriously pop up in
their yards overnight. Though these wild mushrooms can certainly be
dangerous, even store-bought mushrooms should not be fed to rabbits. Mushrooms
can contain a variety of mycotoxins that remain present in the fungi whether
raw or cooked and can be harmful to rabbits if ingested in large enough
quantities. Effects of mushroom toxicity can include diarrhea, gastrointestinal
discomfort, organ damage, and neurological deficits.
Houseplants
When adding
a houseplant to the home, it is safest to treat it as though it is
toxic to your rabbit. Even if the plant you’ve purchased is proven safe for
rabbits to consume, it is often difficult to determine whether or not it may
have been exposed to any chemicals (either directly or indirectly) before you
brought it home. As a result, it is generally best to keep all
houseplants well-trimmed and out of reach from curious little bunny
mouths.
Processed Foods (Bread, Pasta, Cookies, Crackers, Chips, Etc.)
As humans, some of our
favorite foods are convenient, highly processed products that barely resemble
the ingredients from which they were made. While it might seem like a wonderful
bonding opportunity to share a potato chip or a cracker with your bunny, it is
never recommended. Many of the processed foods humans eat are high in
carbohydrates and sugar which can lead to digestive upset, abnormal stools,
abdominal discomfort, and dysbiosis while also substantially increasing
the risk of obesity and obesity-related health concerns. If you want to share a
treat with your bunny, try offering a small amount of appropriate
fruits or opt for one of Oxbow’s many nutritionally appropriate treat
options.
Raw Potatoes
Though not as toxic
as some of the foods on this list, raw potatoes are not particularly
healthy for anyone, including humans. Before being cooked,
potatoes contain a toxic alkaloid called solanine which can lead
to decreased appetite, digestive upset, abdominal pain, and
lethargy in rabbits. Even if toxic quantities of solanine are not
ingested, potatoes are calorically dense and high in starch,
which can throw off a rabbit’s delicate gastrointestinal system
and lead to serious digestive concerns.
It can be extremely
hard to resist the temptation to share some of your
meal with your fur baby, but for their health and
well-being, none of the foods listed above should be fed to your
rabbit. Luckily, there are a host of rabbit-approved greens, fruits, and
veggies that will ensure you can keep mealtime interesting
for your rabbit while also making sure you’re providing the
most nutritionally appropriate diet possible. If there is ever a
time you are unsure whether your rabbit may have ingested a food item
from this list, or if they exhibit any of the symptoms listed above, contact
your veterinarian immediately for advice.
