Can Humans Really Eat Cat Food? The Shocking Truth

Dangers of Eating Cat Food

There are potential health risks associated with humans eating cat food regularly. Some of the key dangers include:

Nutritional Imbalance

Cat food is formulated to meet the specific nutritional needs of cats, which differ greatly from human requirements. Cat food tends to be very high in protein and fat but low in carbohydrates and fiber. Eating cat food could lead to nutritional deficiencies or imbalances in humans over time.

High Fat and Protein Content

The high fat and protein content of cat food exceeds the recommended intake for humans. Too much protein stresses the kidneys while excess fat intake raises cholesterol levels and the risk of heart disease (Can Humans Eat Cat Food? | Meow or Never, 2023).

Low Fiber

Cat food is very low in fiber, which aids healthy digestion in humans. Inadequate fiber could lead to constipation and other gastrointestinal issues.

Bacterial Contamination

Raw or undercooked meats in some cat foods may contain dangerous bacteria like Salmonella or E. coli that can cause food poisoning in humans (Will eating pet food kill you?, 2022).


Cats are the definitive host for Toxoplasma gondii, the parasite that causes toxoplasmosis. Eating undercooked infected meat in cat food significantly increases the risk of humans contracting toxoplasmosis, which can lead to flu-like symptoms or neurological issues (Will eating pet food kill you?, 2022).

Nutritional Content of Cat Food

Cat food is formulated to meet the specific nutritional needs of cats, which differ from human nutritional requirements in a few key ways:

Cat food is generally high in protein and fat, but low in carbohydrates and fiber compared to human diets. Cats are obligate carnivores, meaning they evolved to get most of their nutrients from meat. A healthy feline diet derives the majority of calories from animal-based proteins and fats. Commercial cat foods typically contain 30-45% protein and 20-35% fat on a dry matter basis.[1]

Cat foods have added vitamin and mineral fortification to meet micronutrient requirements. Taurine, an essential amino acid for cats, is often deficient in meat sources and must be supplemented in commercial diets. Other vitamins like A, D, E, and B vitamins are added to create a nutritionally complete cat food.[2]

Overall, commercial cat foods provide balanced nutrition tailored to cats’ unique needs. Their specialized formulation makes them nutritionally inadequate for human consumption.


Reasons People Eat Cat Food

Some people eat cat food out of curiosity or for a thrill, wanting to know what it tastes like. Though just a few bites to satisfy curiosity likely won’t cause harm, it’s still not recommended as cat food is formulated for feline nutritional needs.

In severe cases of poverty or desperation, some people may resort to eating cat food simply because they lack other options for obtaining food. This is an unfortunate reality for some struggling with homelessness, hunger, and food insecurity.

In rare cases, some individuals with mental illness or dementia may accidentally or intentionally ingest cat food. Dementia can cause confusion, memory loss or unusual behavior that leads a person to eat pet food. Certain mental illnesses that affect perception, impulse control or judgment may also contribute to incidents of eating cat food.

While curiosity, desperation and mental health conditions help explain some cases, eating cat food on a frequent basis poses health risks for humans and should be avoided. Safe, nutritious food intended for people should always be the first choice.

Health Risks

There are several health risks associated with humans regularly eating cat food.

One major risk is malnutrition. Cat food does not contain the necessary vitamins and nutrients that humans need for a balanced diet. Cat food lacks adequate amounts of vitamin B, vitamin C, vitamin D, folic acid, and niacin that are essential for human health. Deficiencies in these can lead to anemia, fatigue, poor immune health, and problems with nerves and digestion.[1]

Another risk with consuming cat food frequently is obesity. Cat food contains more calories per serving compared to human food. The high-calorie density combined with lack of portion control can easily lead to unwanted weight gain in humans over time.[2]

Increased cholesterol from eating cat food puts humans at greater risk of heart disease. Cat food contains more fat and cholesterol than the recommended daily amounts for humans, which can negatively impact cardiovascular health.[3]

The high-protein, low-fiber content of cat food can also lead to constipation issues in humans. Without adequate fiber, stools become harder and bowel movements more difficult.[1]

Finally, foodborne illnesses are a risk if the cat food becomes contaminated with bacteria like salmonella. Pet food does not undergo the same safety standards as human food, so deadly pathogens may be present.[3]

Safety Standards

Cat food produced in the United States must meet standards set by the Food and Drug Administration (FDA). The FDA regulates pet food similar to food for humans under the Federal Food, Drug, and Cosmetic Act (FDA). This means cat food must be safe to eat, produced under sanitary conditions, contain allowed ingredients, and be truthfully labeled.

The FDA provides an approved list of ingredients that can be used in cat food, including meats, grains, vitamins, and minerals. Any new food additive must be approved by the FDA before being added to cat food. Cat foods cannot contain harmful levels of contaminants like heavy metals, pesticides, or drug residues.

Pet food manufacturers must follow Current Good Manufacturing Practices (CGMPs) for producing, processing, and holding animal food. This covers facility and equipment standards, production and process controls, and warehousing practices. Unannounced FDA inspections verify adherence to CGMPs (FDA).

FDA testing has found instances of unsafe ingredients, mislabeling, and contamination that led to recalls of various cat food brands. However, most cat foods on the market adhere to FDA standards and regulations for safety and nutritional adequacy.

Taste and Texture

Cat food typically has a much stronger flavor compared to human food. As one person who sampled cat food described, it has a “briny, unnervingly fishy” taste with little depth and can be a bit sour ( This is because cat food contains a high amount of meat protein and fat, which gives it a more pungent taste. Cats have a stronger sense of smell than humans, so they are naturally drawn to these intense flavors.

The texture of cat food also differs greatly from human food. Dry kibble has a very crunchy, brittle texture that humans are not used to eating. It is specifically designed this way to help clean cats’ teeth. Canned wet cat food has an extremely soft, mushy consistency that many find unpalatable. It contains a high moisture content, so it lacks the texture of most human foods.

Alternatives for Humans

While eating cat food isn’t recommended, there are healthy and ethical alternatives that people can access instead.

Local food banks and soup kitchens provide free or low-cost food for those in need. These organizations rely on donations and volunteers to feed their communities. Finding your nearest food bank can connect you with essential grocery items.

There are also government programs that provide food assistance, such as:

  • Supplemental Nutrition Assistance Program (SNAP) – Provides funds through an EBT card to buy eligible grocery items. Visit to check if you qualify.
  • Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) – Provides healthy food, nutrition education, and referrals to health services for qualifying pregnant and postpartum women, infants, and children. Check eligibility at
  • National School Lunch Program – Offers free or reduced-price school lunches for qualifying children. Apply through your child’s school.

These programs aim to provide good nutrition for those who need it most. Looking into these alternatives can help avoid the risks of consuming pet food.

When Cat Food May Be Safe

In most cases, cat food should be avoided by humans. However, there are a couple situations where small amounts may be safe to consume:

Emergency Survival Situations: If stranded without other food sources, small amounts of cat food can provide calories and nutrients to survive. According to Quora, cat food contains the macronutrients and micronutrients humans need in a digestible form. However, it lacks fiber and provides too much protein and fat for regular human consumption. In a life or death situation, the risks of malnutrition outweigh the risks of eating cat food in small amounts. It should only be consumed when no other options are available.

Very Small Amounts for Curiosity: Some people try a bite or two of cat food out of curiosity. According to Vice, a few nibbles likely won’t cause harm in healthy adults. The taste is often unpalatable, acting as a deterrent to overconsumption. However, cat food should never be a regular part of the human diet. Consuming more than a taste could lead to vitamin toxicities over time.

In summary, cat food is not designed for human nutrition needs. However, survival situations or taste tests involving tiny portions are lower risk scenarios. It should always be considered an emergency, last resort food option for people.

Ethical Considerations

There are some ethical issues to consider when it comes to humans eating pet food. One concern is that we may be taking food away from pets who need it. Pet food is formulated specifically to meet the nutritional needs of cats and dogs, not humans. If humans start eating significant quantities of pet food, it could lead to shortages or higher prices, negatively impacting pets who rely on it. According to the ASPCA, some low-income individuals already struggle to properly feed their pets. Taking pet food away from animals to feed humans is ethically questionable.

Additionally, promoting pet food as an option for human consumption can encourage unhealthy eating habits. Pet food does not have to adhere to the same safety and quality regulations as human food. Relying on it as a major part of the diet may lead to nutritional deficiencies or other health issues over time. The American Veterinary Medical Association states that pet food should not replace food fit for human consumption. Encouraging people to eat pet food regularly is ethically concerning since it may promote poor nutrition.

While the taste and affordability of pet food may be appealing, we should consider if taking food away from companion animals, who are dependent on humans, is ethical. Promoting nutritional standards below those for humans also raises ethical questions. Carefully consider these factors before making pet food a regular part of your own diet.

The Bottom Line

Occasional tasting or nibbling on cat food is unlikely to cause harm in healthy humans. However, regularly eating cat food as a significant part of the diet can lead to malnutrition and other health issues. Cat food is formulated to meet the specific nutritional needs of cats, which differ from those of humans in key ways. While cat food may be more appetizing or readily available for some, better and safer alternatives exist to combat hunger.

According to nutrition experts, cat food lacks the proper levels of vitamins, minerals, and protein sources that are essential for human health. Over time, vitamin and protein deficiencies can lead to problems like muscle wasting, bone density loss, vision issues, and neurological disorders. The high ash content found in most cat foods can also put someone at risk of kidney and heart damage. Additionally, some ingredients commonly found in cat food like fish products may contain contaminants that can build up to toxic levels in the human body.

cat and human food side by side

For those facing food insecurity, food banks, soup kitchens, and government nutrition assistance programs exist to provide people-appropriate food. These services are designed to meet human nutritional needs in a much healthier and safer way compared to the risks of a cat food diet. While occasional nibbling of cat treats or wet food does not likely pose a serious safety issue, regular consumption of cat food instead of human food can put your health at risk.
