Which Of These Foods Should You Never Feed A Cat?

Do you ever catch yourself wanting to share your meal with your feline friend? As much as we love our cats and want to include them in our meals, it’s crucial to know which foods are safe for them. Unfortunately, many common human foods can be toxic to cats and cause severe health issues, or even death.

As cat owners, it’s our responsibility to understand the potential dangers of feeding our furry friends certain human foods. From chocolate to onions, there are many harmful substances that can wreak havoc on a cat’s delicate system. These can range from vomiting and diarrhea to more severe conditions such as liver damage and death.

In this article, we’ll delve into the world of cat nutrition and explore Which of these foods should you never feed a cat. We’ll cover everything from commonly known harmful foods to lesser-known items that could harm even the most resilient cats. Whether you’re new to cat ownership or an experienced caretaker, this information could make all the difference in your furry friend’s health and longevity.

So let’s dive in and learn about Which of these foods should you never feed a cat. Be prepared to be surprised by what you discover about feeding your feline companion.


While chocolate may be a beloved indulgence for humans, it can be deadly for cats. Chocolate contains theobromine, a compound that can cause vomiting, diarrhea, seizures, and even death in cats. The darker the chocolate, the more dangerous it is for cats. Baker’s chocolate and dark chocolate are the most toxic forms of chocolate for cats and should always be kept out of reach.

Chocolate isn’t the only food that poses a threat to our feline friends. Xylitol, an artificial sweetener found in many sweets like candy and gum, can lead to liver failure if ingested by cats. Onions and garlic, common ingredients in many dishes, can also be toxic to cats and cause anemia when consumed in large quantities.

Caffeine is another substance that cat owners should keep away from their pets. Ingesting caffeine can lead to restlessness, heart palpitations, muscle tremors, and even death. Coffee, tea, energy drinks, and any other caffeinated products should never be given to cats.

Alcohol is yet another no-go for our feline friends. Even small amounts of alcohol can be dangerous for cats and cause vomiting, diarrhea, difficulty breathing, coma or death.

It’s crucial to understand that even small amounts of these substances can be harmful to your cat’s health. To ensure your cat’s safety, it’s essential to keep all potentially harmful foods out of reach and contact your veterinarian immediately if you suspect your cat has ingested any of these substances.


While it may be tempting to share a piece of chocolate or candy with your cat, it’s crucial to resist those pleading eyes and keep all sugary treats out of reach.

Why is this so important? For starters, most sweets contain sugar, which is not suitable for cats’ digestive systems. Cats cannot digest sugar properly, leading to a host of health problems such as obesity, diabetes, and dental issues. These health concerns can cause long-term damage to your cat’s overall well-being.

But the dangers don’t stop there. Chocolate, in particular, poses a significant threat to cats. This seemingly innocent treat contains a chemical called theobromine that is toxic to cats and can cause seizures, tremors, and even death in severe cases. So while you may be tempted to share your chocolate bar with your furry friend, it’s essential to resist the urge.

Candy and gum are also off-limits for cats as they often contain xylitol. This sweetener can cause insulin release in cats and lead to hypoglycemia (low blood sugar), which can be particularly dangerous for diabetic cats or those with underlying health conditions.

Artificial sweeteners found in sugar-free products are equally harmful to cats. For example, aspartame can lead to neurological damage if ingested in large quantities.

So what can you do to keep your feline friend safe? Firstly, keep all sweets out of reach and educate children about the risks of feeding cats treats. It’s also crucial to contact your veterinarian immediately if you suspect your cat has ingested something harmful.

Onions and Garlic

When it comes to food, it’s important to remember that not all human treats are safe for cats. Onions and garlic are two such foods that you should keep far away from your kitty.

These ingredients may seem harmless to us, but for cats, they can be downright dangerous. Onions and garlic contain a compound called thiosulphate which can cause severe health issues in felines. This toxic component can damage red blood cells leading to anemia, which can cause symptoms like weakness, lethargy, and difficulty breathing. In severe cases, it can even prove fatal.

What’s more, even small amounts of onions or garlic can be toxic for cats. As little as one small onion or a clove of garlic can cause toxicity in cats weighing 5 kilograms (11 pounds) or less. It’s important to note that all forms of onions and garlic are harmful to cats- cooked, raw, powdered, or dehydrated – so even small amounts of onion or garlic powder added to your cat’s food can be harmful.

If you suspect that your feline has ingested onions or garlic, don’t hesitate to seek veterinary care immediately. The symptoms of onion or garlic toxicity may not show up right away. It’s better to play it safe than sorry.


While caffeine may be a beloved morning ritual for us humans, it can be downright dangerous for our feline friends. Caffeine is a stimulant found in coffee, tea, chocolate, and energy drinks, and though it’s safe for moderate human consumption, cats are much more sensitive to its effects. Here’s what you need to know about caffeine and your cat:

Caffeine toxicity symptoms in cats include restlessness, rapid breathing, heart palpitations, muscle tremors, and seizures. These symptoms can quickly escalate to coma or death in severe cases. Even small amounts of caffeine can be toxic to cats.

Cats metabolize caffeine much more slowly than humans, which means even a small amount can build up in their system and cause serious health problems. This is why it’s crucial to keep all caffeine-containing products out of their reach.

Common sources of caffeine that cat owners may not be aware of include coffee grounds, tea bags, dark chocolate, and certain medications. It’s essential to read product labels carefully and store them securely away from your furry friends.

Curiosity can get the best of cats, so it’s important to keep an eye on your beverages and ensure they’re not left unattended. A sip of your morning coffee or tea could lead to severe health problems for your feline friend.

If you’re looking for a way to provide your cat with a little extra energy boost, opt for toys or treats that are specifically designed for feline stimulation. Avoid using caffeinated products altogether as they pose a significant risk to your pet’s health.


This may come as a surprise, but even a small amount of alcohol can cause serious health problems for your cat. Let’s explore why alcohol is so toxic to cats.

First and foremost, alcohol is poisonous to cats. The symptoms of alcohol poisoning in cats include vomiting, diarrhea, difficulty breathing, tremors, and in severe cases, coma or death. Unlike humans, cats have a slower metabolism and cannot process alcohol efficiently. Therefore, even a small amount of alcohol can quickly accumulate in their system and lead to severe health consequences.

It’s vital to understand that alcohol is not only present in alcoholic beverages. Some foods like fruitcake or rum-soaked raisins may contain alcohol as well. Additionally, some household products such as cleaning solutions or hand sanitizers also contain alcohol and must be kept out of reach from cats.

If you suspect that your cat has ingested alcohol, immediate veterinary care is crucial. Your vet may induce vomiting or use activated charcoal to help remove the alcohol from your cat’s system. In severe cases, hospitalization and supportive care may be necessary.

To ensure your feline friend’s safety and wellbeing, it’s essential to keep all alcoholic beverages and products containing alcohol out of reach. Instead, opt for toys or treats designed specifically for feline stimulation.

Other Toxic Foods to Avoid

However, it’s crucial to remember that not all human foods are suitable for cats. In fact, some can be toxic and even fatal to our furry companions. So, what are the other toxic foods that you should avoid when feeding your cat?

First on the list are grapes and raisins. These seemingly harmless fruits can cause kidney failure in cats. Even a small amount of these fruits can have severe consequences. So, make sure you keep your cat away from any dishes or desserts containing grapes and raisins.

Next up is avocado. While this fruit is a popular ingredient in many human dishes, it contains persin which can cause vomiting and diarrhea in cats. In severe cases, it can even lead to breathing difficulties and fluid accumulation around the heart. So, while you might love a good guacamole dip, make sure your cat doesn’t get a taste.

Caffeine and alcohol are also big no-nos for cats. Both substances can cause severe health problems and even death. Caffeine can cause restlessness, rapid breathing, heart palpitations, muscle tremors, and even death. Similarly, alcohol can cause vomiting, diarrhea, difficulty breathing, tremors, coma, and even death.

Lastly, xylitol is another toxic substance that you must keep away from your cats. This sugar substitute is commonly found in sugar-free gum and candy but can also be present in other products like peanut butter or toothpaste. Xylitol can cause insulin release in cats, leading to hypoglycemia (low blood sugar), seizures, and liver failure.

Signs of Food Poisoning in Cats

However, food poisoning is a common problem amongst cats that can lead to severe health complications if not addressed on time. This is why it’s important to be aware of the signs and symptoms of food poisoning in cats.

Vomiting and Diarrhea: If your cat is experiencing frequent vomiting or diarrhea, it could be a sign of food poisoning. Although it’s natural for cats to occasionally vomit or have loose stools, if these symptoms become persistent or severe, it’s time to seek veterinary care.

Loss of Appetite: Has your cat suddenly lost interest in their favorite foods? A sudden loss of appetite is a common symptom of food poisoning in cats. It’s essential to take note of their eating habits and seek professional help if you notice any changes.

Lethargy: If your once lively cat has suddenly become uninterested in playtime and cuddles, it could be a sign that they’re feeling unwell. Lethargy is another common symptom of food poisoning in cats that should never be ignored.

Dehydration: Food poisoning can cause cats to become dehydrated quickly. Signs of dehydration include dry mouth, sunken eyes, and lethargy. If you observe any of these symptoms, it’s time to seek veterinary care immediately.

It’s important to note that certain foods can trigger food poisoning in cats, such as onions, garlic, chocolate, and caffeine. These foods can cause mild upset stomachs or severe reactions in cats.

To prevent food poisoning in your cat, always store their food in a clean, dry place and discard any expired or spoiled food. When introducing new foods to your cat’s diet, always consult with your veterinarian before making any significant changes.

What to Do if Your Cat Has Eaten a Toxic Food

However, despite your best efforts, accidents can still happen, and your cat may consume something toxic. In such cases, it’s crucial to take immediate action and follow these steps to ensure your cat’s safety:

Contact Your Veterinarian Right Away

If you suspect that your cat has eaten something toxic, don’t hesitate to contact your veterinarian immediately. Delaying could be life-threatening to your pet. The sooner you seek help from a professional, the higher the chances of saving your cat’s life.

Gather Information About What Your Cat Ate

While waiting for the veterinarian’s response, try to gather as much information about what your cat ate as possible. The more information you provide, the better the veterinarian can determine the best course of action. If you have the packaging or know the name of the food item, share this information with the vet.

Know the Common Toxic Foods for Cats

Educate yourself on what foods are safe for your cat and which ones are toxic. Some common toxic foods for cats include chocolate, caffeine, onions, garlic, grapes, raisins, and alcohol. Keeping such items out of reach is crucial in preventing toxic food ingestion.

Induce Vomiting (Under Veterinarian Supervision)

In some cases, the veterinarian may instruct you to induce vomiting in your cat. However, this should only be done under their guidance as certain foods can cause more harm when vomited back up. Never attempt to induce vomiting without consulting a professional.

Hospitalization and Treatment

If your cat has ingested a large amount of a toxic substance or if their symptoms are severe, they may need to be hospitalized for treatment and monitoring. Keep a close eye on your cat’s condition and follow all instructions provided by the veterinarian.

Prevention is Better Than Cure

Preventing toxic food ingestion is always better than trying to treat it. Keep all toxic foods, plants, and household chemicals out of your cat’s reach. Always ensure that your furry friend has access to safe and healthy foods.


In conclusion, we all want to treat our feline companions to a special snack or meal every now and then. However, it’s crucial to be aware of the foods that can cause harm and even death to our beloved cats. It’s our responsibility as pet owners to educate ourselves on what is safe for our furry friends.

From chocolate to onions, there are many toxic substances that can wreak havoc on a cat’s delicate system. These harmful foods can cause vomiting, diarrhea, loss of appetite, lethargy, dehydration and even worse health issues. Even small amounts of these substances can be dangerous for your cat’s health.

To ensure your cat’s safety, it’s essential to keep all potentially harmful foods out of reach and contact your veterinarian immediately if you suspect your cat has ingested any of these substances. Prevention is always better than treatment when it comes to toxic food ingestion in cats.

It’s important to be vigilant about what we feed our cats and keep them away from harmful foods such as onions, garlic, chocolate, caffeine, grapes, raisins, alcohol and xylitol. By following these guidelines and providing only safe and healthy foods for our furry friends, we can help keep them healthy and happy for years to come.
