Can Cats Eat Cucumbers? 4 Surprising Benefits

Last updated
Updated by Laura Martin

I’ve often encountered this question from fellow cat parents: “Can cats eat cucumbers?”

It’s a simple question that warrants a straightforward answer: Yes, they can. However, there’s more to it.

As an experienced cat parent, I’d advise you to proceed cautiously. Here’s why.

Cats are obligate carnivores, meaning their bodies are designed to thrive on a meat diet. While some fruits and vegetables can be a healthy addition to their diet, it’s important to remember they’re not necessary.

Cucumbers, for instance, are low in calories, contain several vitamins, and are high in water, making them a potentially hydrating snack.

But does this mean it’s a good idea to include cucumbers in your cat’s diet? Let’s delve deeper.

Short Answer: Can Cats Eat Cucumbers?

Yes, cats can eat cucumbers. Plain cucumbers are safe for your cat to consume in moderation. These green vegetables offer health benefits such as hydration and low-calorie snacks.

What is in a Cucumber

Cucumbers are primarily composed of water—about 96%, to be exact! This high water content can help keep your cat hydrated.

Plus, they are low in calories, making them an excellent choice for weight-conscious kitties.

Cucumbers are also rich in essential vitamins like vitamin K and vitamin C, which help promote overall cat health.

And let’s not forget about antioxidants—those little warriors that wage a constant battle against cell-damaging free radicals.

Health benefits of cucumbers for cats

1. Feeding Cucumbers for Hydration

We all know that cats aren’t the most enthusiastic water drinkers. Some are downright divas when it comes to their water bowls.

Because cucumbers are so hydrating, they can help supplement your fur baby’s water intake, especially on hot summer days when dehydration can quickly become a concern.

Remember, cucumbers aren’t a substitute for water, but they’re a fantastic way to sneak in a little extra hydration.

2. Low-Calorie Cat Treat Options

Cucumbers are a perfect low-calorie snack, at only 15 calories per 100 grams.

Substituting high-calorie cat treats with cucumber slices can be a great way to maintain your cat’s weight without depriving them of their beloved snack time.

Of course, every cat has unique preferences, so monitor their reactions to ensure they’re enjoying this new occasional treat.

3. Cucumbers Contain Antioxidants

Antioxidants are like the unsung heroes of the nutritional world. They fight off harmful free radicals and help maintain your cat’s overall health.

Cucumbers happen to be a source of antioxidants, making them a brilliant addition to your cat’s diet.

While research on the benefits of antioxidants for cats is still ongoing, some studies suggest that they help support the immune system, enhance cardiovascular health, and even slow the aging process.

4. Chewing Exercise

Beyond the nutritional benefits, cucumbers also have a satisfying crunch, making for a great chewing exercise.

As your cat bites into a cucumber slice, the crunching action can help remove plaque, leading to healthier gums and teeth.

So, next time you’re slicing up a cucumber, consider setting aside a piece for your feline friend to munch on.

How to Feed Cucumbers to Your Cat

What to Keep in Mind When Serving Cucumbers to Your Cat

There are a few things to remember before tossing your furry friend a cucumber slice.

First and foremost, remember to wash the cucumber thoroughly.

Like us, our feline friends can be affected by pesticides and other harmful substances often found on the skin of fruits and vegetables.

So, remember to give that cucumber a good rinse before moving on to the next step. Next, be sure to slice and peel the cucumber.

Why peel it, you may ask?

While the skin of a cucumber isn’t harmful to cats, it can be difficult for them to digest. Plus, it’s much easier for them to munch on a peeled cucumber slice. Lastly, keep it simple—no salt, no spices, and definitely no dressings. Our feline friends don’t need these additions to enjoy their cucumbers.

Not to mention, certain seasonings and dressings can be harmful to cats.

Observing Your Cat’s Reaction

You’ve prepared the cucumber, and it’s time for the taste test. It’s crucial to observe your cat’s reaction to this new treat. Not all cats react the same way to new foods. While some gobble up the cucumber slices, others may turn their noses up.

And that’s okay. Just like us, cats have their unique taste preferences.

For those finicky cats, especially the adventurous outdoor cats, finding the right balance in their diet is key to ensuring they get all the nutrients they need.

If your outdoor cat is one of the pickier eaters, finding the best cat food for outdoor cats can make all the difference in meeting their nutritional needs. More importantly, monitor your cat for signs of allergies or digestive issues. Although rare, some cats may be allergic to cucumbers.

If you notice any changes in your cat’s behavior, eating habits, or bathroom routine, it might be time to consult your vet.

Potential Risks of Feeding Cucumber to Cats

A Cat’s Nutritional Requirements

While the occasional vegetable cat treat (like a sliver of cucumber) won’t harm your feline friend, it’s essential to remember that cats thrive on a high-protein diet.

This means they depend on nutrients found only in animal products. Overloading your cat’s diet with too many plant-based foods, including cucumbers, can lead to deficiencies in essential nutrients like taurine, arachidonic acid, and vitamin A—nutrients they cannot obtain from plants.

This can then disrupt their nutritional balance and potentially lead to health issues down the line.

How Much Cucumber Can My Cat Eat?

Now, here’s where a lot of us cat parents go wrong.

It’s tempting to shower our cuddly companions with cat treats, but remember, moderation is key.

As a general rule of thumb, cucumbers (or any vegetable treat) should only make up about 10% of your cat’s total diet.

Serving cucumber once or twice a week is enough for your cat to enjoy this crunchy treat without interfering with their nutritional needs.


Yes, cats can eat cucumbers, but they should do so sparingly and under your watchful eye. As with any new cat food, it’s best to introduce it slowly and monitor your cat for adverse reactions.

Remember, your cat’s diet should primarily consist of high-quality, balanced cat food that meets their nutritional needs. If you’re considering adding new foods to your cat’s diet, it’s always a good idea to consult your vet first.
