Dangers of Feeding Human Food to Cats

Cats are beloved members of our families, and as pet owners, we always want to ensure their well-being. While it may be tempting to share our meals with our feline friends, it is crucial to understand that feeding human food to cats can be dangerous and should not be encouraged. There are several human foods that are toxic to cats and can pose serious health risks. In this article, we will explore the potential dangers of feeding human food to cats and the adverse effects it can have on their health.

Dangers of Feeding Human Food to Cats

Toxic Foods for Cats

It is essential to be aware of the specific foods that are toxic to cats in order to prevent accidental ingestion. Here are some common foods that can be toxic to cats:

Green Tomatoes

Green tomatoes contain solanine, a toxic substance that can lead to gastrointestinal distress in cats. Symptoms may include vomiting, diarrhea, and abdominal pain. It is best to refrain from feeding tomatoes to your feline companion.

Raw Green Potatoes

Similar to green tomatoes, raw green potatoes contain solanine. Ingesting raw green potatoes can cause severe digestive upset in cats. Ensure that your cat does not have access to raw potatoes to avoid any potential health complications.


Chocolate contains theobromine, a stimulant that can be toxic to cats. Even small amounts of chocolate can cause symptoms such as vomiting, diarrhea, increased heart rate, and even seizures. It is crucial to keep all chocolate products out of your cat’s reach.

Grapes and Raisins

Grapes and raisins have been known to cause kidney failure in cats. Even small amounts can lead to symptoms like vomiting, diarrhea, lethargy, and decreased urine production. Make sure to keep grapes and raisins away from your curious feline companion.


Avocado contains a substance called persin, which can be toxic to cats. It can cause vomiting, diarrhea, and even heart congestion. Keep avocados safely stored away from your cat to avoid any potential health risks.

Alcohol can negatively affect cats in the same way it affects humans. Even a small amount of alcohol can cause severe intoxication, leading to symptoms such as disorientation, lack of coordination, lethargy, and even coma. It is crucial to ensure that your cat does not have access to any alcoholic beverages.

Other Common Toxic Foods

In addition to the items mentioned above, there are several other human foods that can be toxic to cats. These include onions, garlic, raw eggs, caffeinated beverages, artificial sweeteners, high-fat foods, and meat trimmings. It is best to avoid feeding these foods to your cat to prevent any potential health complications.

Toxicity Symptoms and Risks

Feeding toxic foods to cats can result in various symptoms and pose significant health risks. It is important to be vigilant and recognize any signs of toxicity in your cat. Here are some common symptoms and risks associated with ingesting toxic foods:

Toxicity Symptoms and Risks in cat

Vomiting and Diarrhea

One of the most common symptoms of toxicity in cats is vomiting and diarrhea. If you suspect your cat has ingested something toxic, observe for any signs of gastrointestinal distress.

Loss of Appetite

Toxic foods can cause a loss of appetite in cats. If your cat suddenly refuses to eat, it may be an indication of toxicity.


Feeling lethargic and sluggish is another potential symptom of toxicity in cats. If your usually energetic cat becomes unusually tired and lacks enthusiasm, it could be a cause for concern.

Abdominal Pain

Toxic foods can lead to abdominal pain in cats. They may exhibit signs of discomfort, such as pacing, restlessness, or even aggression when their stomach is touched.

Muscle Tremors and Seizures

In severe cases, ingesting toxic foods can cause muscle tremors and seizures in cats. These involuntary movements can be distressing and require immediate veterinary attention.

Kidney Damage

Certain toxic foods, such as grapes and raisins, can cause kidney damage in cats. Kidney failure can have serious long-term consequences and may require extensive medical intervention.

Liver Failure

Some toxic foods, like onions and garlic, can damage a cat’s liver. Liver failure can lead to a range of health issues and may require specialized treatment.

Respiratory Distress

In some cases, toxicity can result in respiratory distress in cats. They may experience difficulty breathing, coughing, or wheezing, indicating a potentially life-threatening situation.

Cardiac Issues

Certain toxic foods can affect a cat’s heart, leading to irregular heartbeats or even cardiac arrest. If your cat shows signs of rapid breathing or an irregular pulse, seek immediate veterinary assistance.

The Effect of Allium Vegetables

Allium vegetables, including onions, garlic, and related root vegetables, can have specific adverse effects on cats. These foods contain compounds that can be toxic and lead to anemia in cats.

The Effect of Allium Vegetables


Onions, in particular, contain a substance called N-propyl disulfide, which can cause oxidative damage to a cat’s red blood cells. This damage can result in anemia, leading to symptoms such as weakness, pale gums, and lethargy.


Garlic, similar to onions, also contains compounds that can be toxic to cats. Ingesting garlic can lead to a breakdown of red blood cells and subsequent anemia.

Related Root Vegetables

Other root vegetables, such as shallots and leeks, can also have similar toxic effects on cats. It is important to be cautious and avoid feeding any Allium vegetables to your feline companion.

Anemia in Cats

Anemia, caused by the ingestion of Allium vegetables, can have serious health implications for cats. It can result in fatigue, reduced oxygen-carrying capacity, and overall weakness. If you suspect your cat has ingested onions, garlic, or related root vegetables, seek veterinary assistance as soon as possible.

Other Harmful Foods

Apart from Allium vegetables, there are several other human foods that can be harmful to cats and should be avoided.

Other Harmful Foods

Meat Trimmings

Feeding cats meat trimmings can lead to digestive upset and potential pancreatitis. The high fat content in these trimmings can cause inflammation in the pancreas and result in severe abdominal pain and discomfort for your feline friend.

Raw Eggs

Raw eggs, particularly when consumed in large quantities, can pose a risk of Salmonella or E. coli infection in cats. These bacterial infections can cause severe gastrointestinal distress and require veterinary attention.

Caffeinated Beverages

Caffeinated beverages, such as coffee, tea, or energy drinks, should never be given to cats. The caffeine content can cause restlessness, increased heart rate, tremors, and even cardiac issues.


Xylitol, a common sugar substitute found in many human foods, can be toxic to cats. Ingesting xylitol can lead to a sudden release of insulin, causing a rapid drop in blood sugar levels. This can result in weakness, seizures, and, in severe cases, liver damage.

Artificial Sweeteners

Artificial sweeteners, like those containing aspartame or saccharin, can be harmful to cats. They can cause digestive upset and, in large amounts, potentially lead to health complications.

High-Fat Foods

Feeding cats high-fat foods can contribute to weight gain and obesity-related health issues. Excessive consumption of fatty foods can lead to digestive upset, pancreatitis, and even liver problems in cats.

Immediate Actions to Take

If you suspect or witness your cat ingesting toxic foods, it is crucial to take immediate action to ensure their safety and well-being. Here are some steps to follow:

Immediate Actions to Take

Contact a Veterinarian

In case of an emergency, contact your veterinarian immediately. They can provide guidance and advise you on the best course of action based on the specific situation. Acting promptly can make a significant difference in your cat’s outcome.

Animal Poison Control Center

If your veterinarian is unavailable or if you need immediate assistance, contact an animal poison control center. They have trained professionals who can provide guidance on first aid measures and whether or not you should seek veterinary care.

Observe and Document Symptoms

While awaiting veterinary advice, carefully observe your cat and document any symptoms they may exhibit. This information will be valuable for your veterinarian in assessing the severity of the situation and determining the appropriate course of treatment.

Prevent Further Ingestion of Toxic Foods

If you can safely do so, remove any remaining toxic foods from your cat’s reach. Preventing further ingestion is essential in minimizing the potential harm caused by toxic substances.

Induce Vomiting (if instructed)

In some cases, a veterinarian or poison control expert may advise you to induce vomiting in your cat. However, it is crucial to note that this should only be done under professional guidance and if it is deemed safe for your cat’s specific situation.

Do Not Administer Home Remedies

While it may be tempting to try home remedies or over-the-counter treatments, it is crucial to avoid administering any form of medication or treatment without professional guidance. These remedies can sometimes do more harm than good and may potentially worsen the situation.

Potential Long-Term Effects

Feeding toxic foods to cats can result in long-term health complications if not addressed promptly. Here are some potential long-term effects:

Potential Long-Term Effects

Organ Damage

Certain toxic foods can cause damage to vital organs in cats, such as the kidneys or liver. This damage can have long-term consequences and may require ongoing medical management.

Renal Failure

Kidney damage resulting from toxic food ingestion can progress to renal failure in cats. Renal failure can significantly impact a cat’s quality of life and may necessitate specialized treatment and dietary management.

Reduced Lifespan

Chronic poisoning from toxic foods can reduce a cat’s lifespan. The long-term effects of toxicity can lead to a weakened immune system, decreased vitality, and overall reduced longevity.

Chronic Illnesses

Ingesting toxic foods can predispose cats to various chronic illnesses, such as gastrointestinal disorders, heart conditions, or metabolic imbalances. These chronic conditions require ongoing management and can significantly impact a cat’s overall health.

Digestive System Complications

Feeding toxic foods to cats can result in a range of digestive system complications. It is important to be aware of these potential issues:

Digestive System Complications

Upset Stomach

Toxic foods can cause an upset stomach in cats, leading to symptoms like vomiting, diarrhea, and general discomfort. These digestive upsets can be both uncomfortable and distressing for your feline companion.


Ingesting toxic foods can result in diarrhea in cats. Diarrhea can be acute or chronic and may require medical intervention to resolve and prevent dehydration.


Gastroenteritis, inflammation of the gastrointestinal tract, can occur as a result of ingesting toxic foods. This condition can cause symptoms such as vomiting, diarrhea, abdominal pain, and loss of appetite.


Certain high-fat foods can trigger pancreatitis in cats. Pancreatitis is the inflammation of the pancreas and can cause severe abdominal pain, vomiting, and potential complications.

Weight Management and Obesity

Feeding human food to cats can contribute to weight gain and obesity, which can have serious health implications for our feline friends. Here are some factors to consider:

Excessive Caloric Intake

Human food often contains higher calorie content than is suitable for cats. Feeding excessive amounts of human food can result in a high caloric intake, leading to weight gain in cats.

Weight Gain

Weight gain is a leading cause of obesity in cats. Feeding human food, particularly high-fat or high-carbohydrate foods, can significantly contribute to weight gain, increasing the risk of obesity-related health issues.

Obesity-Related Health Issues

Obesity in cats can lead to a range of health problems, including diabetes, joint issues, respiratory difficulties, and a weakened immune system. Maintaining a healthy weight is vital for a cat’s overall well-being and longevity.

Behavioral Changes

Feeding human food to cats can also result in behavioral changes that can impact their daily lives and interactions with their owners. Here are some common behavioral changes to be aware of:

Behavioral Changes

Food Aggression

Feeding cats human food can trigger food aggression, where they become possessive of their food and display aggression towards other animals or even humans. This behavior can lead to tense interactions and make mealtime stressful for both your cat and yourself.

Increased Begging

Cats that are regularly fed human food may develop a habit of begging for food at inappropriate times or from anyone around them. Increased begging can be disruptive to your household and create challenges in maintaining a healthy feeding routine for your cat.

Table Scrapping

Feeding cats table scraps can condition them to expect food whenever you sit down to eat. This can lead to persistent begging and may result in your cat consuming inappropriate or unhealthy foods.

Reduced Interest in Cat Food

Feeding cats human food can reduce their interest in commercial cat food, which is formulated to provide the necessary nutrients for feline health. Over time, this can lead to nutritional imbalances and deficiencies in your cat’s diet.

In conclusion, feeding human food to cats is not recommended due to the potential dangers and health risks involved. Many human foods are toxic to cats and can cause various symptoms, leading to serious health complications. It is crucial to be aware of these toxic foods and take immediate action if your cat ingests them. By providing a balanced and appropriate diet specifically designed for cats, you can ensure their overall well-being and prevent the potential adverse effects of feeding human food. Remember, your veterinarian is always your best resource for guidance and advice when it comes to your cat’s dietary needs. Keep your feline friend safe by offering them a cat-friendly diet and avoiding the temptation to share your human meals.
