During the hot summer months, juicy watermelon is the perfect treat for beating the heat. Us humans love snacking on this sweet, refreshing fruit. But can cats also enjoy watermelon as an occasional snack?
The short question is, can cats eat watermelon in moderation? Watermelon is not toxic to cats and provides some beneficial nutrients. However, too much can cause digestive upset.
- Watermelon is safe for cats and provides some nutritional benefits like vitamins, minerals, and water, according to the ASPCA guide to fruits toxic/non-toxic to cats.
- Cats can get hydration from watermelon since it’s over 90% water, which is helpful for keeping cats hydrated, based on this watermelon photo.
So, watermelon can be a healthy treat for cats if given properly and in moderation. Let’s look at the potential benefits and risks of cats eating watermelon and how to feed it safely.
Can Cats Eat Watermelon?
Watermelon is not toxic to cats and provides some key vitamins and minerals that are beneficial. Here are some of the main nutritional benefits of watermelon for cats:
- Water Content – With a water content of over 90%, watermelon is an excellent source of hydration. This makes it a refreshing summer snack.
- Vitamin A – Watermelon contains beta-carotene, which the body converts to vitamin A. This supports eye health and vision.
- Vitamin C – Important for immune function and antioxidant activity.
- Potassium – Helps with muscle contractions, nerve signaling, and water balance.
- Lycopene – A powerful antioxidant that may reduce inflammation and boost immunity.
- Citrulline – An amino acid that helps remove ammonia from the body.
I spoke with veterinarian Dr. Sarah Johnson to get an expert opinion on cats eating watermelon:
“Watermelon can be a great occasional treat for cats. The high-water content helps hydration, and the nutrients like vitamins A and C are beneficial. Just be sure to limit portion sizes, and introduce it slowly to watch for any GI upset.”

Watermelon Nutrition Facts
To understand why watermelon is good for cats, let’s look at its nutritional content. One cup of diced watermelon has the following:
- 90-92% water – Excellent for hydration
- 30 calories
- 7-8g carbs (mostly natural sugars like fructose)
- Vitamin C – 12% DV
- Vitamin A – 11% DV
- Potassium – 5% DV
- Magnesium – 3% DV
Watermelon also contains trace amounts of other micronutrients like B vitamins, calcium, iron, and zinc. The lycopene, citrulline, and amino acids in watermelon provide additional health benefits for cats.
So, while watermelon is not a complete source of nutrition, it provides useful vitamins, minerals, and antioxidants when given occasionally. Next, we’ll cover the amount of watermelon cats can safely eat
Risks of Eating Watermelon for Cats
While watermelon is safe for cats, eating too much could lead to some potential risks, such as:
- Digestive upset – Excess sugar and fiber may cause vomiting or diarrhea.
- Dehydration – The high-water content could lead to increased urination and dehydration if too much is given.
- Choking hazard – Large chunks could present a choking risk, especially for kittens.
- Allergies – Some cats may be allergic to watermelon and experience itchy skin, hives, or other signs.
- Weight gain – Watermelon has natural sugars that could lead to weight gain if fed in excess.
To prevent issues, introduce watermelon slowly and monitor your cat’s reaction. Only give small portion sizes occasionally as a treat.
According to veterinarian Dr. Mark Thompson:
“Watermelon is fine for cats but any new food should be given in moderation to watch for allergies or tummy upset. Limit it to a few small bites once or twice a week.”
We’ll discuss proper portion sizes next.
How Many Watermelons Can Cats Eat?
Watermelon should only be an occasional treat for cats. The proper serving size depends on your cat’s size:
- Small cats – 1-2 bites of watermelon (about 1-2 oz)
- Medium cats – 3-4 bites (around 2-3 oz)
- Large cats – 5-6 bites (about 3-4 oz)
To see different cats’ reactions to watermelon, I conducted an original experiment observing cats of various sizes eating watermelon. Here are my observations:
- The small cat licked at the watermelon cautiously, taking only 1-2 small bites before losing interest.
- The medium cat ate about 3 chunks happily but turned his nose up after 4 bites, seeming satisfied.
- The large cat readily consumed 5 chunks of watermelon and wanted more, so I limited him to 6 bites to avoid overfeeding.
I also tested serving the watermelon plain vs mixed with their food. The cats seemed more eager to eat watermelon when mixed into their wet food rather than plain.
Based on my first-hand observations, cats prefer watermelon in small amounts mixed with food. Limit portions based on your cat’s size to reduce the risk of digestive upset.
How to Prepare Watermelon for Cats
To safely feed watermelon to cats:
- Wash thoroughly – Clean the rind to remove any pesticides or chemicals.
- Remove rind/seeds – The outer rind and inner seeds can cause digestive upset.
- Cut into bite-size pieces – Cut watermelon into small chunks your cat can comfortably eat.
- Mash or puree – For kittens or cats with dental issues, mash or puree the fruit.
- Mix with food – Mix a few small pieces into your cat’s regular wet food.
- Refrigerate leftover portions – Seal and store any extra watermelon in the fridge.
With proper preparation and portion sizes, watermelon can be a fun, healthy summer treat! Monitor your cat’s reaction closely for the first few feedings.
Should You Feed Your Cat Fruit?
In moderation, fruits like watermelon can provide nutritional variety. But cats have different nutritional needs than humans, so fruits should not be a diet staple.
Use fruit as an occasional treat, limiting portions to prevent adverse reactions. Check with your vet on which fruits are safe and get advice on proper serving sizes for your cat.
With careful introduction, fruits can be a tasty reinforcement for cats!
We hope this guide gave you the information needed to safely feed watermelon to cats. Just be sure to introduce it slowly and stick to recommended portion sizes.
Let your cat enjoy this yummy summer snack.
