What Fruits Can Cats Not Eat?

As a cat owner, it’s natural to want to share your favorite fruits with your feline friend. But before you do, it’s important to know which fruits can be harmful to their health. After all, just because something is good for us doesn’t mean it’s safe for our furry companions.

Did you know that grapes and raisins can cause kidney failure in cats? Or that avocados contain persin – a substance that can lead to vomiting and diarrhea in our feline friends? These are just a few examples of the fruits that should never make it onto your cat’s plate.

Other fruits to avoid include citrus fruits like oranges and lemons, which can cause stomach upset and skin irritations. Cherries can also lead to gastrointestinal issues, while plums and peaches pose choking hazards due to their pits.

But don’t worry – there are still plenty of cat-friendly fruits out there. Bananas, blueberries, and watermelon are all safe options in small portions. Just remember to always remove any seeds, pits, and peels before serving them up.

As a responsible pet owner, it’s crucial to stay informed about what foods are safe for your furry friend. By knowing what fruits cats cannot eat, you’ll be able to keep them healthy and happy for years to come.

Cats as Obligate Carnivores

This means that unlike humans and other omnivorous animals, their bodies are specially designed to consume and digest meat. In the wild, cats hunt and eat small prey like mice, birds, and rabbits. Their digestive systems are perfectly adapted to break down and absorb the nutrients found in animal protein.

It’s important to note that cats do not have the necessary enzymes to break down plant matter efficiently. Fruits and vegetables are not a natural part of a cat’s diet and can even be harmful in some cases. Feeding your cat a diet high in fruits or vegetables can lead to digestive issues such as vomiting and diarrhea. It can also cause nutritional deficiencies as cats require specific amino acids, vitamins, and minerals that are only found in animal-based protein.

While some fruits may be safe for cats to consume in small amounts, it’s vital to understand which fruits should be avoided altogether. This knowledge can prevent accidental poisoning or harm to your cat’s health. Grapes, raisins, citrus fruits like oranges, lemons, and limes, avocado, onions, and garlic should all be avoided when feeding your cat. These foods can cause severe health problems such as kidney failure, vomiting, diarrhea, anemia, and heart failure.

Grapes and Raisins: Toxic to Cats

Grapes and raisins, for example, can cause severe health problems in cats, including kidney failure. In this article, we’ll delve deeper into why grapes and raisins are harmful to cats and what you should do if your cat ingests them.

While the exact substance responsible for their toxicity is still unknown, it’s clear that grapes and raisins can be dangerous to cats even in small amounts. Interestingly, it’s believed that the harmful substance is present only in certain types of grapes and raisins. When ingested, these fruits can cause a range of symptoms in cats, including vomiting, diarrhea, lethargy, loss of appetite, abdominal pain, and decreased urine production. In severe cases, it can even lead to kidney failure.

If you suspect that your cat has ingested grapes or raisins, it’s crucial to act fast by seeking veterinary care immediately. Even if your cat hasn’t displayed any symptoms yet, it’s best to err on the side of caution and get them checked out by a professional. Some cats may not show symptoms until several hours after ingestion, and by then it may be too late to prevent kidney damage.

To protect your cat from accidental ingestion of grapes or raisins, it’s important to be vigilant about keeping these fruits out of reach. This means not only keeping fresh grapes and raisins off of countertops and tables but also being cautious about giving your cat foods that may contain them as ingredients. For example, certain types of trail mix or baked goods may include grapes or raisins.

Citrus Fruits: Unsafe for Cats

While cats may be curious creatures and love to experiment with different foods, it’s crucial to keep them away from certain fruits, including citrus.

Citrus fruits such as oranges, lemons, limes, grapefruits, tangerines, and mandarins contain essential oils and psoralens in their leaves, peels, and seeds. These toxic compounds can result in severe health problems for your furry companion, ranging from vomiting and diarrhea to lethargy, weakness, and tremors. In some severe cases, ingestion of citrus fruits can even lead to liver failure or death.

Therefore, it’s best to keep citrus fruits out of reach of your kitty at all times. It’s not just the fruit itself that is harmful; even the juice and any products containing citrus extracts should be avoided. This includes cleaning solutions with citrus scents. It’s essential to note that cats are sneaky creatures and can sometimes grab a piece of citrus fruit when you’re not looking. Thus it’s crucial to store these fruits safely and away from your cat’s reach.

Avocado: A No-No for Cats

When it comes to caring for your feline friend, providing the best possible nutrition is crucial. However, certain foods that are healthy for humans may pose a serious threat to cats. Avocado is a prime example of this.

Although a delicious and nutritious fruit for humans, avocado can be quite dangerous for cats. This is because it contains a toxin called persin, which is present in all parts of the fruit including the flesh, skin, and pit.

When a cat consumes avocado, the persin toxin can trigger vomiting, diarrhea, and difficulty breathing. In severe cases, it can even lead to heart failure and death. The severity of these symptoms depends on the amount of avocado consumed by the cat.

Avoid giving your cat any avocado products, including guacamole or other dishes that contain avocado. Even if your cat seems to enjoy the taste of avocado, it’s not worth risking their health and wellbeing.

If you suspect that your cat has ingested avocado, contact your veterinarian immediately. They will provide advice on how to proceed and may recommend treatment options based on the severity of the situation.

Being vigilant about what your cat eats is crucial as a responsible feline owner. It’s important to keep toxic foods such as avocado out of your cat’s reach to ensure their long-term health and happiness.

Onions and Garlic: Potential Health Risks to Cats

Although these ingredients are common in human food, they are toxic to our beloved pets.

Onions, garlic, as well as chives and leeks, belong to the Allium family. The compounds found in these ingredients can cause oxidative damage to feline red blood cells, leading to anemia. Large amounts of onions or garlic can cause vomiting, diarrhea, lethargy, and loss of appetite within a few hours or days after ingestion.

If left untreated, onion and garlic toxicity can cause severe health problems like hemolytic anemia or organ damage. As a responsible cat owner, it is essential to be mindful of the potential risks associated with feeding your pet foods that contain onions or garlic. Be cautious when sharing human food with your cat and read ingredient labels carefully before purchasing any commercial cat food products.

If you suspect that your cat has ingested onions or garlic, contact your veterinarian immediately for proper treatment. Your vet will likely recommend inducing vomiting and providing supportive care such as IV fluids or blood transfusions if necessary.


As a loving cat owner, you may be tempted to share your favorite fruits with your furry companion. However, it’s crucial to understand that not all fruits are safe for cats to consume. While some fruits may be okay in moderation, others should be avoided altogether.

Grapes and raisins may seem like healthy snacks for humans, but they can cause kidney failure in cats. Avocados contain persin, a substance that can lead to vomiting and diarrhea in our feline friends. And while we might think of citrus fruits like oranges and lemons as refreshing treats, they can cause gastrointestinal issues for cats.

It’s important to remember that cats are obligate carnivores and require meat-based protein for their nutritional needs. Feeding them a diet high in fruits or vegetables can lead to deficiencies in essential amino acids, vitamins, and minerals.

Other fruits that should be avoided include cherries, plums, and peaches due to choking hazards or digestive problems they may pose.

As responsible pet owners, it’s up to us to stay informed about what foods are safe for our furry friends.
