Can Cats Eat Watermelon?
Cats can eat small amounts of watermelon flesh, but only occasionally. Seeds and rind should be avoided, and watermelon offers no real nutritional benefit for cats.

It’s a common summer occurrence… you’re cutting into a slice of watermelon, and your curious cat suddenly appears to investigate.
So, can cats eat watermelon? In short: yes. But only in small amounts, and only the flesh.
Watermelon isn’t toxic to cats, but there are a few things to be aware of before sharing a slice.
Is Watermelon Safe for Cats?
Yes, watermelon flesh is generally safe for cats in small amounts.
However, some parts should always be avoided:
- Seeds: can cause digestive issues or blockages
- Rind (skin): tough to chew and difficult to digest
If you do offer watermelon, it should always be:
- Seedless
- Rind removed
- Cut into small, manageable pieces
Can Cats Digest Watermelon Properly?
Cats can cope with small amounts, but fruit isn’t something their bodies are designed for.
Watermelon is:
- High in natural sugar
- Not nutritionally necessary for cats
Because cats are obligate carnivores, their diet should be centred around meat rather than fruit.
So, while a tiny taste is unlikely to harm them, it doesn’t add anything beneficial either.
Why Do Some Cats Like Watermelon?
Not all cats will be interested, but some are drawn to:
- The texture
- The moisture content
- The novelty!
This curiosity is completely normal. Cats often investigate unfamiliar foods, even if they don’t actually want to eat them.

Can Watermelon Help Keep Cats Hydrated?
Because watermelon contains so much water, many people wonder if it’s a good way to keep their cat hydrated.
While it may provide a little extra moisture, watermelon shouldn’t be used as a way to keep your cat hydrated. If you’re looking to add more moisture to their diet, Applaws Bone Broth can be poured over meals or served as a tasty treat.
How Much Watermelon Can Cats Eat?
If your cat is interested, only offer a very small amount.
A bite or two of watermelon is more than enough for cats.
Too much can cause:
- Upset stomach
- Loose stools
Watermelon should always be an occasional treat, not part of their regular diet.
What Should You Do If Your Cat Eats Too Much Watermelon?
If your cat has eaten a larger amount, keep an eye on them.
Watch for:
- Vomiting
- Diarrhoea
- Changes in behaviour
If they show symptoms or you’re unsure, it’s always best to speak to your vet.
A Better Way to Treat Your Cat
Cats are naturally curious at mealtimes, but not everything they show interest in is right for them.
If you’re looking to treat your cat, it’s better to choose something designed around their natural needs.
Simple, real-meat recipes, like Applaws, give them something naturally satisfying and healthy for their diet, without the risks that come with human foods.
