Can Cats Eat Sweetcorn?

Sweetcorn is a common food that might spark curiosity in cat owners wondering if it's safe for their pets. Understanding its benefits and potential risks can help you make informed decisions about sharing this snack with your feline friend.

Sweetcorn is a popular choice for humans, enjoyed in many forms like creamed, on the cob, or in chowders, but can your feline companion eat corn safely? While corn is a common filler ingredient in cat food, the type of corn humans eat, such as corn chips or sweetcorn, raises questions about its Nutritional Value for carnivore cats.


Before offering any type of corn to your cat, it’s important to understand what they truly need in their diet. Cats are obligate carnivores, meaning they need protein rich foods and specific vitamins and minerals. Corn husks and some forms of corn can be difficult for cats to digest and may even cause Vomiting. Is corn a good option or a bad choice for your cat? Read on to learn whether corn is safe for your feline companion.

Is Corn Good for Cats?

Fortunately, corn is not toxic to cats, but it doesn’t offer much nutritional value for your feline companion either. Cats are obligate carnivores, meaning they need most of their vitamins and minerals from meat based proteins to thrive. While corn is often added to cat food as a filler ingredient or a source of fatty acids, it is specially processed to make it easier for carnivore cats to digest. However, the type of corn humans eat, such as corn chips or sweetcorn on the cob, is not always a good option for your pet. If not thoroughly processed, corn can be tough for cats to digest and may even cause vomiting.

How Much Sweetcorn Can Cats Eat?

Now that we’ve answered the question, "Can cats eat sweetcorn?" with a cautious "yes, but in moderation," how much is safe for your cat to eat?


Sweetcorn doesn’t offer significant nutritional value for your feline companion, so it should be treated as an occasional snack rather than a dietary staple. According to the PDSA, treats should make up no more than 10-15% of your cat’s daily caloric intake, ensuring their primary cat food provides the Essential Nutrients they need.


Each cat’s caloric needs vary based on size and activity levels. For an average 4kg Indoor Cat, the daily caloric requirement is about 190 calories, meaning treats should not exceed 28.5 calories. This equates to roughly 35g of sweetcorn, keeping moderation key to maintaining a healthy, balanced diet.

Can Corn Be Bad for Cats?

Corn is high in carbohydrates, which cats don’t require in their diet. It can lead to digestive issues and, over time, may contribute to Obesity or even Diabetes in your feline companion. Additionally, repeated exposure to corn can sometimes result in Allergies in certain cats. With minimal nutritional value for cats, corn is considered empty calories and is not a suitable option for a regular treat.

How Much Corn Can Cats Eat?

Offering sweetcorn to your cat as an occasional treat is generally safe, but it’s important to exercise moderation. Can cats eat sweetcorn? Yes, but too much can pose risks since it lacks the essential nutrients cats need to thrive.


Here are some of the risks associated with overfeeding sweetcorn to your feline friend:

1. Nutritional Deficiencies

Cats are obligate carnivores, meaning their diet must be rich in animal protein to provide vital nutrients. Taurine, an essential amino acid found only in animal meat, supports heart, eye, and digestive health. Corn doesn’t contain taurine, and a diet high in this vegetable could lead to serious complications such as blindness and heart disease. That’s why cat food is specially formulated with the taurine cats need to stay healthy.

2. Digestive Issues and Allergies

Although can cats eat sweetcorn in small amounts? Yes, but large quantities are hard for cats to digest due to their carbohydrate content. Corn is also a common allergen among pets, meaning some cats may react poorly to it, leading to tummy upsets or allergic reactions.

3. Feline Obesity

Sweetcorn should never make up more than 10-15% of your cat’s daily calories. Overfeeding this carb heavy treat can result in Obesity, putting your cat at risk of Diabetes, joint problems, and other health issues.

4. Dental Health Concerns

The carbohydrates in sweetcorn can contribute to plaque buildup, increasing the risk of dental disease and tooth loss if your Cat’s Teeth aren’t brushed regularly or monitored by a vet.

While sweetcorn can be a tasty and safe treat in moderation, it should never replace the meat based nutrients your cat needs for optimal health.

Can Cats Eat Corn on the Cob?

Corn cobs can pose serious risks to cats. If a cat ingests part of a cob, the size and texture may prevent it from passing through their digestive system, potentially causing a gastrointestinal blockage that requires emergency surgery. Even smaller pieces of the cob can be a choking hazard.


To keep your feline safe, never allow your cat to eat corn on the cob. If your cat does manage to chew on a cob when you’re not watching, contact your veterinarian immediately for guidance. Should your cat show signs of distress such as lethargy, Vomiting, Diarrhea, or any other unusual behavior, seek veterinary care without delay.

Can Cats Eat Corn Husks?

Corn husks are also unsafe for cats. While they may enjoy chewing or playing with the fibers, corn husks are indigestible and can lead to gastrointestinal blockages. Their rough texture can irritate the lining of the intestinal tract, potentially causing vomiting, diarrhea, and abdominal discomfort.


If you catch your cat playing with a corn husk, remove it immediately and offer a safer, more suitable toy instead. If you think your cat has ingested part of a corn husk, contact your veterinarian for advice on the best course of action.

Can cats eat corn chips?

Corn chips are not suitable for cats because they often contain harmful ingredients, including:


1. Excessive salt

2. Spices

3. Preservatives


The high fat content in corn chips can contribute to rapid weight gain, increasing the risk of obesity, diabetes, and other serious health issues in cats.

Why does your cat eat corn?

Carnivores like cats typically don’t crave sweetcorn or any other type of corn. If your cat seems unusually interested in eating it, it could be due to:


  • A rare preference for the taste.
  • A nutritionally insufficient diet, causing them to seek out whatever is available.

Since corn offers no real benefit to your cat’s diet, it’s essential to understand why they’re drawn to it. A more likely reason is that their current food lacks essential nutrients. Feeding poor-quality cat food over time can lead to nutritional deficiencies, which might result in the following symptoms:


Bald patches or thinning fur.

A dull or brittle coat.

Irregular stools, such as diarrhea or constipation.

Sudden behavioral changes, including lethargy.

Unusual skin pigmentation.

Fragile or weakened bones.

Significant weight or muscle loss.

Decreased appetite.

Recurrent eye infections.

Lack of coordination.


If you notice any of these signs, consult your veterinarian to review your cat’s diet and overall health.

FAQ

Is it safe to feed a cat raw sweetcorn?

Is it safe to feed a cat raw sweetcorn? While cats can eat sweetcorn in moderation, offering it raw is not recommended. Raw sweetcorn can be difficult for cats to digest, potentially leading to stomach upset, vomiting, or diarrhea. Cats are obligate carnivores, meaning they require nutrients primarily from animal based proteins, and raw sweetcorn offers little to no nutritional value to support their health. Additionally, raw corn husks or kernels can pose a choking hazard or risk of gastrointestinal blockage. If you choose to give your cat sweetcorn, ensure it is cooked, plain, and served in small amounts as an occasional treat, ensuring your feline companion's primary nutrition comes from balanced cat food.

Is it okay for cats to eat sweetcorn?

Is it okay for cats to eat sweetcorn? Yes, cats can eat sweetcorn, but only in moderation and as an occasional treat. Sweetcorn is not toxic to cats, but it provides little nutritional value for their diet since cats are obligate carnivores and require nutrients like taurine and protein from animal sources. Feeding too much sweetcorn can lead to issues such as digestive upset, obesity, or even nutritional deficiencies if it replaces essential cat food. Always ensure the sweetcorn is cooked, plain, and free of additives like butter, salt, or spices to make it safe for your feline companion. While sweetcorn is generally safe, it should not become a regular part of your cat’s diet.

Is corn good for cat teeth?

Is corn good for cat teeth? No, corn is not beneficial for a cat’s teeth and can actually contribute to dental issues. The high carbohydrate content in corn can lead to plaque buildup on a cat’s teeth, increasing the risk of dental disease, tartar, and gum problems if not managed with regular brushing or dental care. Unlike a cat’s natural diet of meat, which can help maintain oral health through chewing, corn lacks the abrasive texture needed to clean teeth. If your cat consumes foods containing corn, it’s important to monitor their dental health and consult your veterinarian for advice on maintaining proper oral hygiene.

Why do cats like sweetcorn?

Why do cats like sweetcorn? While not all cats enjoy sweetcorn, some are drawn to its taste and texture. Cats may like sweetcorn because its natural sweetness and crunchy texture appeal to their curiosity and senses. However, another reason could be that their diet is lacking essential nutrients, prompting them to seek out additional food sources, even those that aren't species-appropriate. Cats are obligate carnivores, meaning they don’t require sweetcorn or any plant-based foods for nutrition, so their interest in it is likely due to novelty rather than a dietary need. If your cat consistently seeks out sweetcorn, it may be worth reviewing their cat food to ensure it meets all their nutritional requirements.

Can cats eat tinned sweetcorn?

Can cats eat tinned sweetcorn? Yes, cats can eat tinned sweetcorn, but it’s not the healthiest option and should only be offered in moderation. Tinned sweetcorn often contains added salt, preservatives, or other seasonings that are not safe for cats and could lead to dehydration or digestive issues. Cats are obligate carnivores and don’t need sweetcorn in their diet, as it provides little nutritional value and lacks the essential nutrients they require from meat-based proteins. If you choose to let your cat try tinned sweetcorn, ensure it is rinsed thoroughly to remove excess salt and serve only a small amount as an occasional treat. Always prioritize high-quality cat food to meet your feline companion’s nutritional needs.
