Can cats eat watermelon?

After discussing the nutritional facts and health benefits of watermelons, it is with pleasure to announce that yes, cats can actually enjoy the goodness of the tropical fruit, but with a catch: they can only eat them in moderation.

Feeding them in small amounts is the key to keep your cat safe from possible harms due to the fact that watermelons may upset your feline friend’s stomach. If moderation is not taken seriously, it can cause digestive problems which you don’t want your cat to experience. As a responsible pet owner, it is vital to always consider your little’s furry companion’s safety as the first and foremost priority.

Apart from that, there are also other factors to consider before actually feeding them with the mouthwatering treat, specifically the risks.

  1. Your cat’s digestive system is much smaller and more sensitive.
  2. If your cat indulges in watermelon more than usual, it may result to digestive problems.
  3. Your cats’ digestive system cannot digest sugar as efficiently and properly as humans do.

The seeds and rind can be very harmful

Whenever we think of watermelons, we always consider the process of eating them. We remove the seeds and we do not usually eat its rinds.

The rind is the green hard shell of the watermelon while the seeds are found inside the fruit scattered all over the red juicy fruit. As we humans avoid them, it is relative to also do the same for our lovable pet cats.

In this part of the summary, I will educate you with the possible harms these two components of the watermelon for your pet cat.

The rinds

In some studies, eating the rinds of the staple summer fruit can be beneficial for humans. It helps stimulate better and healthier heart and even suggests better performance in bed. However, these benefits do not concern your cat’s health and in reality, even do more harm than good.

Because the rind can be hard for your cat to digest, it is safe to be cautious and just remove them before it causes problems such as gastrointestinal upset.

The seeds

The seeds found in the watermelon must also be removed to avoid complications when you feed this fruit to your cat. This primary reason is to avoid the possibility of an upset stomach to your cat.

  1. It may result to intestinal blockage.
  2. The seeds contain harmful compounds such as cyanide also known as cyanogenic glycosides.
  3. Digesting the seeds may result to cyanide-based poisoning.

And even though it actually takes quite a massive amount of seeds before it can cause severe harm, it is still highly advisable to be precautious at all times, especially if it is your cat’s first time to try the delicious treat.

Apart from these facts, the seeds may even result to allergies because different types of cats have a certain allergic reaction to specific food including fruits and meat.

Symptoms of watermelon allergies or toxicity

As humans, we are also sometimes picky with the food we eat. We try to avoid indulging ourselves with treats that do not interest us. Moreover, we completely disregard food that may lead us to harm such as rashes caused by an allergic reaction.

As responsible pet owners such as yourself, it is wise to feed your furry feline friend with an ample amount, especially if it’s their first time. After which, study and examine how your cat reacts to the watermelon.

This is to avoid the following:

  1. Vomiting
  2. Diarrhea
  3. Indigestion
  4. Poisoning
  5. Intestinal blockage
  6. Choking
  7. Internal damage

Meanwhile, if these symptoms will continue, stop feeding watermelons to your cat because clearly, they are neither comfortable nor compatible with the said fruit.

What to do if my cats have allergic reactions to watermelons?

As pet owners, it is our duty to always care for them. This includes overseeing their habits and always taking into consideration their wants and needs. This trait will help us become closer with our loving little pal.

And as we try to understand their needs and wants, sometime we overlook important details because we really want them to try some things that we do. In this case, letting our feline friend eat watermelons  without cautioun may lead to complications.

One possible reason for allergic reactions is the fact that cats are not all the same, and furthermore their digestive system is totally different from ours. Some cats are more compatible with certain types of food compared to others.

Here’s a step-by-step plan for you to become a more responsible cat owner:

  1. All cats are hunters. They prey on meat and not fruits. You should be aware of this fact because these cats, being carnivores draw back from their ancestors who used to feed on small rodents.
  2. To avoid a possible allergic reaction, make sure the watermelon is fresh and clean. Assure that the watermelon you want them to eat is not rotten.
  3. Always make sure to remove the seeds and the rinds to avoid complications.

  • Stop feeding your cat watermelons.
  • Go to your veterinarian and have your cat checked.


Going back to the first question, the answer is yes. Your furry cat companion can enjoy munching on watermelons, as long as you feed them in moderation. Furthermore, since most domestic cats such as your house pet have easily adapted to their environment and feeding on the food from our table.

It is always safe to note the following safety precautions such as removing the seeds and rinds, as well as examining whether your cat is allergic to watermelons or not. Remember, an observation can give you a lot of possibilities, so be sure to keep a close eye on your pet. Lastly, your cat is a carnivore and watermelons cannot replace meat.
