Are Cats Animals That Can Eat Fruit?

It is well known that cats like watermelon, but not all fruits. Cats being purely carnivores and hunters concentrate all their interest in foods that have protein content, which is why their interest in fruits, in general, is quite low. That said, it is important to mention that it does not mean that cats have any problem with fruits, what it means is that they will always prefer other types of food before leaning towards this option, which is very good when you understand their high content of natural sugars and the damage that their excessive consumption would imply for the health of cats.

Can Watermelons Kill Cats?

A cat consuming watermelon is definitely not at risk of death if its consumption is done in moderation under the supervision of its owner, however, it is important to thoroughly investigate some important aspects regarding watermelons. Watermelon is a sweet fruit that is in the pumpkin family. It has very high water and vitamin content and contains no fat or cholesterol. Its pulp has up to 13% of digestible sugars made up mainly of glucose and fructose.

Watermelon is an adjuvant in strengthening the body and normalizing metabolic processes. However, it should be taken into consideration that watermelon can also accumulate in its interior a large number of nitrates due to incorrect agricultural practices by its growers, which generates that in very specific occasions its ingestion is dangerous. This situation could cause in statistically very low cases food poisoning by nitrates, causing symptoms of vomiting and diarrhea in cats.

Some other risks associated with the consumption of watermelon in cats are directly related to certain parts of this fruit that should be totally avoided, which is why the intake of the watermelon should be controlled and supervised by the owner of the animal, who should prepare each portion or reward of this fruit by removing the following elements.


Unfortunately, the seeds have certain compounds inside, such as cyanide, which make them totally toxic for cats, in case of ingesting them, the cat will present severe vomiting and diarrhea. This is explained by the fact that, unlike humans, cats are very small animals, so the effects of these substances will always be more intense and dangerous. Another point against the seeds is that they cannot be digested and in an extreme case could cause choking of the feline or respiratory obstruction.


The rind is 100% indigestible by the digestive system of cats, its accidental consumption by the cat would not be fatal, however, it is better to be safe than sorry, it is recommended that before giving watermelon to your cat you completely remove the rind and all the seeds and thus avoid future stomach discomfort to the cat.
