Can Rabbits Eat Watermelon? How Much and How Often

Yes, a rabbit can eat watermelon as an occasional treat. The Rabbit Welfare Association and Fund (RWAF) lists "Watermelon (seedless)" under "Fruit (Occasional Treats Only)," and the House Rabbit Society says to limit fruit and carrots, which it calls treats, to "a very small amount once or twice per week."

Rabbits primarily need a diet rich in hay, with a balance of vegetables and a limited number of pellets, and treats like watermelon should only make up a small portion of their overall intake.

Can rabbits eat watermelon?

The RWAF names the fruit. Its page of safe vegetables and herbs for pet rabbits has a section called "Fruit (Occasional Treats Only)." The list reads: apple (seeds removed), banana (green or under-ripe preferred), blueberries, cantaloupe melon, honeydew melon, raspberries, strawberries, and watermelon (seedless).

The House Rabbit Society, the RSPCA, and PDSA do not name watermelon. Their rule for fruit in general is the one that applies. The House Rabbit Society says "All fruits are considered “treats” because of their high sugar content." The RSPCA says "Certain fruits and vegetables can be given in moderation as an occasional treat." PDSA's safe treats "to be given in very small amounts, and avoided in overweight rabbits" include squash, apples, bananas, kiwi fruit, melon, pears, plums, and strawberries.

How much watermelon can a rabbit have?

Very little, and not often. The RWAF says fruits are counted as treats because they are "generally high in sugars," and that a treat should be "no more than once or twice a week." The House Rabbit Society gives the same weekly limit and adds a share of the diet: "Fruits should be considered a treat and be less than 5% of your bunny’s daily diet."

The House Rabbit Society puts carrots in the same treat category as fruit, so one weekly limit covers them all. If your rabbit gets a few blueberries on Monday, that counts as one of the week's treats. The RWAF's examples of a treat are "a grape or a slice of apple."

The San Diego House Rabbit Society gives sizes: fruit "needs to be limited to very small piece: one grape (cut in half), 1/4” slice of banana, a 1-inch cube of apple or carrot, etc." VCA says fruit can be fed in "very limited quantities," no more than one to two tablespoons of "high-fiber fresh fruit such as apple, pear, or berries," once or twice a week. Neither page names watermelon.

PDSA ties a treat to the rest of the day's food: "When you give your rabbit a treat, make sure you adjust their meal size accordingly, so that they don’t have too many calories that day." It says treats are to be avoided in overweight rabbits, and that a pet parent who is worried about a rabbit's weight, body shape, or diet should ask a vet.

What should a rabbit eat every day?

Hay and grass come first. The RSPCA says "A rabbit diet should consist mostly of fresh hay and grass (85%), with some leafy greens (10%) and a few pellets or nuggets (5%)." The House Rabbit Society's breakdown is 80 percent hay, 10 percent vegetables, 5 percent pellets, and less than 5 percent fruits and treats.

Rabbits require a diet high in fiber to keep their digestive systems in check. PDSA says "A balanced diet, high in fibre, is essential for rabbits," and that feeding the wrong thing can lead to "serious problems such as dental disease and gut stasis."

Water goes with every meal. The RSPCA says "Make sure they always have fresh water available to drink," and PDSA says rabbits should have "constant access to fresh, clean water that is changed daily." Watermelon is mostly water and provides hydration, but it does not take the place of the bowl.

Why fruit is limited for rabbits

Watermelon is not just water and sugar; it is also a significant source of vitamins and minerals. Like other fruit, watermelon is a treat because of its high sugar content. The House Rabbit Society says bunnies "have a sweet tooth and, if left to their own devices, will devour sugary foods to the exclusion of healthful ones." That is why the weekly limit has to come from the pet parent.

Susan Smith, PhD, writing for the House Rabbit Society, explains where the sugar goes: "excessive sugar is converted to fat, or will pass into the cecum where the bacteria will use it for energy and then rapidly overgrow, possibly leading to bacterial imbalance and gi stasis. The same can occur after feeding too much fruit."

The San Diego House Rabbit Society adds that "too many sweets will cause your rabbit to become obese and can cause soft stools and diarrhea, and dental problems." Too much fruit can lead to digestive issues, including diarrhea and GI stasis. The RSPCA describes gut stasis as "a slowdown or stopping of the normal movement of food through the digestive system," and says it "needs immediate attention."

Can rabbits eat watermelon seeds?

Take them out. The RWAF lists the fruit as "Watermelon (seedless)" and lists apple as "Apple (seeds removed)." The RSPCA's list of foods to avoid includes "Fruit seeds/pits."

Seeds are also a choking hazard, so cut each piece from flesh that has none. A seedless watermelon removes the step, and the RWAF names that kind in its list.

Can rabbits eat watermelon rind?

None of the sources on the small pet list gives a rule for the rind or skin of a watermelon, so this page gives none. The RSPCA says "If you’re planning to change what they eat, speak to your vet first for advice."

Can rabbits eat melon, cantaloupe, or honeydew?

The RWAF lists cantaloupe melon and honeydew melon next to watermelon under "Fruit (Occasional Treats Only)." PDSA lists "Melon" among its safe treats, and the San Diego House Rabbit Society lists melon under "Rabbit-Safe Fruits (in small portions)."

Which foods does the RWAF list as lower in sugar than fruit?

The RWAF list has a separate group called "Botanical Fruits (Lower in sugar than true fruits, but still best fed as part of a varied diet.)" It names courgette (including the flowers, excluding the leaves), cucumber, marrow, pumpkin, squash (all varieties), and ripe tomato flesh.

How do you introduce watermelon to a rabbit?

Start with a very small piece. The RSPCA says "Avoid sudden changes in their diet, as this can upset a rabbit’s digestive system and make them ill." PDSA says to "Start by mixing a small amount of new food with current food" and then "gradually increase the amount of new food and reduce the amount of old food each day." It adds "Fresh foods should also be introduced in this way" and "Monitor for signs of a stomach upset and slow the process down if you notice any problems."

Remember to introduce any new food gradually. The VCA line is about vegetables: "Introduce new vegetables slowly and in small quantities, and monitor for soft feces, diarrhea, or signs of gas pain." Fruit that arrives too fast or in too large a piece can cause diarrhea and other digestive health issues.

Wash the fruit first. The RWAF says "Wash all fresh foods thoroughly," and PDSA says "Never feed your rabbit anything you can’t identify, or that’s been in contact with pesticides or fertilisers, and always wash fresh food before giving it to them."

What if my rabbit ate too much watermelon?

Watch the droppings and the appetite. The RSPCA says "If your rabbit has diarrhoea, is passing soft faeces or the quantity and consistency of their poo pellets doesn’t return to normal within 24 hours, book an appointment with a vet as soon as possible." It also says a rabbit that refuses its food should see a vet to check for problems such as gut stasis, which "needs immediate attention."

Which other treats are on the lists?

The Sacramento House Rabbit Society's special treats list is apple, bananas, blueberries, cranberries (dried), grapes, melon, orange, papaya, peach, pear, pineapple, plums, raspberries, and strawberries. The House Rabbit Society says "High glycemic fruits such as bananas and grapes should be used only as occasional treats." All fruit treats for your bunny share the one weekly limit.
