Watermelon contains antioxidants and vitamins, among other valuable compounds. Theyâre not that valuable to your cat, though. As a carnivore, they rely on the nutrients in animal products only. They can synthesize their own vitamin C, and antioxidants are abundant in fish and eggs. So, can cats eat watermelon for any health benefits?
Health Benefits of Watermelon for Cats
Watermelon is unlikely to provide any health benefits for cats. Vitamin C is an important nutrient for all animals, and watermelon does contain this vitamin. However, cats can synthesize it in their bodies and donât need to get it from fruits or vegetables.
Watermelon also contains lycopene, a carotenoid that protects animal cells from damage. This can be beneficial to cats, but thereâs not much lycopene in watermelon. In fact, eggs contain carotenoids too â they give the yolk its orange color. Animal products are always better sources of nutrients for cats than plants, which are difficult for their digestive system to process.
What About Hydration?
Can cats eat watermelon as a hydrating snack? Cats are prone to dehydration, especially if their diet mainly consists of dry food. They may like watermelon because itâs wet, but itâs not the best option. The high sugar content can actually lead to dehydration in cats. If your cat isnât drinking enough, try installing a kitty water fountain or feeding them wet food more often.
Risks of Feeding Your Cat Watermelon
The sugar in watermelon can be harmful to cats and lead to weight gain, as catsâ bodies arenât optimized to use carbohydrates for energy. Itâs not as risky as feeding them chocolate, but too much can give your pet an upset stomach or worse. As with any new food, introduce it gradually and only offer a small piece at a time.
Watermelon seeds can also be dangerous â your cat may choke on them or the seeds can get stuck in their digestive system. Make sure to remove all seeds before giving your cat watermelon. Itâs best not to let them play with the seeds, either, as they may chew them and ingest the cyanide thatâs found inside them.

What to Do if Your Cat Eats Watermelon?
If your cat has eaten watermelon, monitor them for any adverse reactions. If they start to vomit, have diarrhea, or seem generally unwell, take them to the vet. These symptoms can also be caused by other things your cat has eaten, so itâs best to be safe and rule out stomach irritation or poisoning by other plants.
Which Cats Should Never Eat Watermelon?
Diabetic cats are more sensitive to the sugar in watermelon and can get sick from eating it. If your cat has diabetes, avoid giving them watermelon. Also, if your cat is overweight or has a liver disease, consult with your veterinarian before feeding them this fruit. In general, itâs best not to give watermelon to cats â they can get all the nutrients they need from their regular diet.
Editorâs Note
A perfect feline diet is based on animal products. Fruits like watermelon can be an occasional treat, but they shouldnât replace your catâs regular food. It is because the sugar content in watermelon can be harmful to cats and their digestive system is not designed to process plant-based foods. If you want to give your cat a special treat, opt for cooked pieces of meat or fish instead.
Can Kittens Eat Watermelon?
Like adult cats, kittens shouldnât eat this fruit either. Their digestive system is still developing, so they canât process plant-based foods very well. Even seedless watermelon can give them an upset stomach and diarrhea. If you want to give your kitten a treat, try feeding them a small piece of cooked chicken instead.
Can Cats Eat Watermelon Rind?
What about the green rind? Is it safe for cats to nibble on the watermelon rind? The rind is actually more nutritious than the flesh, as it contains high concentrations of vitamins B and C. However, itâs still not something that cats need in their diet. The hard texture makes it difficult for them to digest.
If your cat is trying to eat watermelon rinds, they may need more fiber in their diet. In that case, potted grass is a more natural option for your feline friend. You can easily grow your own wheatgrass or oat grass and let your cat munch on it whenever they want.
Can Cats Drink Watermelon Juice?
No, cats should not drink watermelon juice. The sugar and acid can upset their stomach and cause diarrhea. If youâre looking for a refreshing treat to share with your cat, try freezing some water in an ice cube tray and adding it to their water bowl on a hot day. Theyâll love playing with the ice cubes and stay hydrated at the same time.
Are Other Melons Safe for Cats?
The answer is the same for all melons: no, cats should not eat them. This includes cantaloupe, honeydew, and other varieties of melon. All of these fruits are too sugary for cats and can cause digestive problems.
Your Cat Doesnât Need Watermelon â Try These Treats Instead
Can cats eat watermelon on occasion, or just once? Itâs not toxic to them, but if you want to give your cat a special treat, try one of these options cats can eat safely:
- cooked chicken;
- canned tuna (in water);
- salmon (cooked or canned);
- a boiled egg;
- a teaspoon of plain yogurt.
Again, if your cat has any health issues, check with your vet before giving them any new food. Some of the above options are high in fat, which makes them bad choices for obese cats.

Donât Feed Your Cat Watermelon â But Donât Panic if They Steal Some
In conclusion, can cats eat watermelon? While it wonât kill them, itâs not necessary or particularly beneficial. Watermelon does contain sugar, which can be harmful in large quantities. If your cat has eaten watermelon, monitor them for any adverse reactions and call the vet if they seem unwell.
