Can Cats Eat Watermelon

Many cat owners reach for watermelon on hot days—but before sharing, here’s what veterinarians want you to know.

After cucumber, watermelon, with its 92% water content, is an excellent choice for staying hydrated. While this fruit is undoubtedly a great way for humans to maintain hydration, concerns arise when they begin sharing it with domestic cats. However, responsible cat parents first ask the question: Can cats eat watermelon?

Yes, cats can eat watermelon as long as the seeds and rind are removed and only if they’re neither diabetic nor allergic to the fruit. Watermelon not only helps with hydration but is also a good source of vitamin C and potassium. While it may offer some benefits, it shouldn’t be a regular part of a cat’s daily diet.

But what if your kitty often reaches out for a slice when you’re enjoying one? That’s when you really need to know whether it’s safe for cats to eat watermelon this frequently. And the best place to turn for a clear answer is an expert like Pet First, where qualified vets share their professional advice with you.

Are There Any Nutritional Benefits of Watermelon for Cats?

To find the answer, you first need to look at the nutritional profile of this fruit.

Watermelon contains:

  • Vitamins: A, B6, and C
  • Minerals: Potassium and copper
  • Carbohydrates
  • Sugar
  • Plant-based compounds: Citrulline and lycopene

While vitamins and minerals can offer some health benefits, the high content of sugar and carbohydrates makes it a controversial choice.

Watermelon also contains fiber and is low in calories. For these reasons, it can be a safe option for cats but only as an occasional treat.

Is Watermelon Safe for Cats?

Yes, it’s completely safe to feed your cat watermelon as long as you take the necessary precautions. These include starting with small amounts to see how they react, offering only the soft fleshy part (without the rind and seeds), and making sure it doesn’t become a regular part of their diet.

Things to Consider When Offering Watermelon to Cats

  • Cats require a high-protein diet, and watermelon doesn’t contain protein in significant amounts. Therefore, it should never replace their regular meals.
  • The fruit is high in carbohydrates and sugar, which cats don’t need. In diabetic cats especially, these can do more harm than good.
  • Watermelon seeds contain cyanide, which can potentially cause toxicity in felines. Always remove the seeds before offering any to your cat.
  • Large quantities of watermelon may upset your cat’s stomach. Overconsumption can lead to vomiting, diarrhea, and abdominal discomfort.

At What Age Can Cats Eat Watermelon?

Cats over 12 months of age can typically eat watermelon without significant risk.

However, young felines have a more sensitive gastrointestinal system, which makes them more prone to intestinal obstruction and stomach upset.

Similarly, elderly cats often suffer from health issues like obesity and diabetes. Feeding watermelon to such cats may worsen their condition due to its sugar and carbohydrate content.

Can Cats Eat Watermelon Seeds or Not?

No, cats must not eat watermelon seeds under any circumstances. Here are two reasons why you should avoid feeding cats watermelon with seeds:

  • Choking Hazard: Although the seeds are small, they are often present in large quantities. When given to kittens just a few weeks or months old, they may cause choking or even intestinal blockage.
  • Potential Toxicity: Watermelon seeds contain cyanide, a poisonous compound. While the amount is usually minimal, overconsumption can still have harmful effects.

Final Thoughts 

You should never feed your cat anything, no matter how delicious or healthy it seems to you, without a vet’s advice. While some fruits and snacks are both nutritious and tasty for humans, they can have a significant negative impact on cats. Always consult an expert before introducing any new food to your cat’s diet.
