Cats can be fed a ketogenic diet, but it is important to be mindful of the risks. Cats are obligate carnivores, meaning they must eat meat to survive. They have no nutritional need for vegetables or carbohydrates, so a ketogenic diet may be suitable, as it is low in carbohydrates and high in fats and proteins. However, it is important to note that a ketogenic diet can increase the risk of pancreatitis in cats if they consume too much fat. Additionally, it is crucial to ensure that the diet meets all the nutritional requirements of a feline, including supplements like taurine if organ meat is not included.

Cats are obligate carnivores and require meat in their diet
Cats are obligate carnivores, meaning they require meat in their diet. Their gastrointestinal tracts and metabolism have adapted to eating meat, and they can't digest plant material well. They require essential nutrients, such as arachidonic acid, cobalamin, and retinol (vitamin A), that only meat can provide. While dogs and humans can turn beta-carotene, a plant product, into vitamin A, cats cannot. They must consume retinol from meat.
Taurine is another example of a nutrient that cats can only get from meat. Dogs and humans can synthesize sufficient taurine, but cats cannot and must consume it in their diet. Without taurine, a cat's heart cannot function correctly, and if deprived for too long, they will become anorexic and eventually die.
Cats also need a high-protein diet, and meat provides them with the protein they need to thrive. Kittens need even more protein than adult cats, putting them above many other mammals. In the wild, cats usually prey on small animals, such as mice and birds, but as pets, they may only eat canned or dry cat food.
It is important for cat owners to mimic the high-protein, low-carbohydrate diet that cats would naturally eat in the wild. Dr. Deb Zoran, a professor at the Texas A&M College of Veterinary Medicine & Biomedical Sciences, recommends feeding cats canned food with a protein content of 40 percent or higher and a carbohydrate content of 10 percent or lower. Canned food also helps cats meet their daily water needs, as they are used to getting a large percentage of their water from their diet.
While it is possible to keep dogs healthy on a plant-based diet, a vegan diet is not appropriate for cats. Cats are not adapted to a plant-based diet, and their digestive systems are not geared to handle it. They will not be able to get all the nutrients they need and may develop deficiencies. Therefore, it is crucial to include meat in a cat's diet to ensure they stay healthy and obtain the necessary nutrients for proper growth, development, maintenance, and reproduction.

The keto diet is low-carb, high-fat, and adequate protein
The keto diet is a low-carbohydrate, high-fat, and adequate-protein diet. The reduction in carbohydrates puts the body into a metabolic state called ketosis, where it burns fat for energy instead of carbohydrates. This can lead to weight loss and increased energy. Typically, the keto diet restricts net carbohydrate intake to around 50 grams per day, with some more restrictive variants of the diet suggesting 20 grams per day. However, it is important to note that the number of net carbs can vary depending on the specific foods consumed.
To calculate the number of net carbs, you subtract the amount of fibre from the total number of carbs. If the food is processed, you also subtract half of the sugar alcohol content. Net carbs refer to the carbs that the body can absorb and utilise for energy. By limiting net carbs, the body is forced to burn fat, resulting in the production of ketones, which are acids that appear in the blood and urine.
The keto diet recommends that 70% to 75% of a person's intake should be fat, with some suggesting a range of 60% to 70%. This high-fat intake is crucial to prevent hunger and provide adequate nutrition. The remaining intake consists of moderate amounts of protein, typically ranging from 20% to 35%, and a small percentage of carbohydrates, usually around 5% to 10%.
It is important to note that excessive protein consumption on a low-carb diet can prevent the body from reaching ketosis. This is because, in the absence of sufficient carbohydrates, the body can convert amino acids from proteins into glucose. Therefore, it is recommended to have moderate protein intake, with a suggested range of 0.7 to 0.9 grams of protein per pound of body weight.
The keto diet involves significantly reducing carbohydrates and increasing fat intake. This shift can be challenging for those accustomed to a standard diet, which typically includes 50% to 55% carbohydrates. The keto diet recommends replacing high-carb foods with fatty foods such as eggs, dairy, meat, and fish, as well as non-starchy vegetables. It is important to consult a healthcare professional before starting the keto diet, as it may not be suitable for everyone.

Cats don't rely on ketones, but they do rely on fats and proteins for energy
The ketogenic diet is a low-carbohydrate, high-fat, and adequate-protein diet. It was initially developed in the 1920s to treat epilepsy. When humans follow this diet, their metabolic system stops relying on carbohydrates and starts relying on fats and proteins. During this process, the body makes ketones, which it uses for fuel.
Cats, on the other hand, do not rely on ketones. As obligate carnivores, they have a very efficient metabolic system that directly converts proteins and fats into glucose, which is used for energy. This is why cats are considered perfect predators. While they don't rely on ketones, they do rely on fats and proteins for energy, and they do so more efficiently than humans.
The cat food market is dominated by "kibble" or "dry food" diets, which can contain over 50% carbohydrates. This is problematic because carbohydrates are not easily digestible for cats and can lead to obesity and health issues. A ketogenic diet for cats can help manage weight and reduce the risk of obesity-related health issues. It is also believed to offer other benefits, such as better brain function, seizure control, and improved age-related neurological disorders.
However, it is important to note that a ketogenic diet for cats should be carefully formulated. While fats and proteins are essential, excessive fat intake can increase the risk of pancreatitis in cats. Additionally, some keto diet staples, such as xylitol, chocolate, and nuts, can be dangerous to cats. Therefore, it is crucial to consult with a veterinarian before placing cats on a ketogenic diet to ensure they receive a balanced and safe diet.

Cats on a high-carb diet are at risk of cancer, obesity, and kidney disease
Cats are obligate carnivores, meaning they are biologically designed to eat meat. Their digestive systems are not equipped to handle a high-carb diet, as they lack the enzymes to process these nutrients efficiently. As such, a high-carb diet can contribute to metabolic disorders, including diabetes mellitus, chronic pancreatitis, liver disease, and obesity. Obesity is a growing problem among cats, with around 50% of the world's cat population being classed as obese.
Cats are naturally equipped to handle a low-carb, high-fat and protein diet. Their metabolic system does not rely on ketones, but rather a straight protein (amino acid)/fat conversion to glucose, which is used for energy. This is why a ketogenic diet is often recommended for cats, as it closely resembles their natural diet.
The typical commercial cat food on the market often contains a high proportion of carbohydrates, with some having over 50% carbs. This is in stark contrast to the diet of a wild cat, which would naturally consist of around 2% carbs. This discrepancy has led to speculation that high-carb diets could be detrimental to a cat's health and may be the primary cause of feline obesity.
By reducing the number of carbohydrates in a cat's diet, you can help to reduce the risk of obesity and other health issues. It is recommended that carbs should not account for more than 3% of a cat's daily food intake. A ketogenic diet can help to achieve this, as it focuses on meat, which is a natural part of a cat's diet.
In addition to the health benefits, a ketogenic diet can also help with weight management and may even lead to diabetes remission in cats. With the right diet, you can help your cat live a longer and healthier life.

There is no such thing as keto dry cat food
The ketogenic diet is a popular weight-loss diet for humans. The diet is based on low-carb, high-fat foods, which induce ketosis, a metabolic state in which the body relies on fat and protein for energy instead of carbohydrates. While the keto diet has been touted as beneficial for humans, its application for cats is less clear.
Cats are obligate carnivores, which means they have a purely meat-based diet. They do not rely on ketones for energy like humans do; instead, they directly convert protein and fat into glucose for energy. As natural carnivores, cats are already on an extreme version of the keto diet. Their natural diet contains zero carbs and is high in protein and fat.
The idea of a keto diet for cats is based on the assumption that it will help them maintain a healthy weight and improve their overall health. However, there is limited evidence to support this claim. While it is true that a high-fat, low-carb diet can be beneficial for weight management, it is important to remember that cats require a high-protein diet. In fact, a true keto diet for cats would be counterproductive as it is low in protein.
Additionally, the majority of cat food on the market is dry food, which is often high in carbohydrates and other non-species-appropriate ingredients. Even premium dry food options are not suitable for a keto diet as they do not meet the low-carb, high-fat criteria. While there are low-carb dry cat food options available, they are not truly keto. The closest option to a keto diet for cats is wet food, which is typically lower in carbohydrates.
In conclusion, while the idea of a keto diet for cats may be appealing to some, the reality is that there is no such thing as keto dry cat food. Cats are already natural carnivores and do not require a keto diet. Instead, they need a high-protein, species-appropriate diet that may include low-carb, wet food options but should not be limited to dry food.

Frequently asked questions
The ketogenic diet is a high-fat, moderate-protein, and very low-carbohydrate diet. Carb intake is typically reduced to 50 grams per day, but some sources suggest limiting it to 20 grams to guarantee ketosis.
Ketosis is a metabolic state in which the body breaks down stored fat into molecules called ketone bodies to use for energy instead of carbohydrates. This occurs when there is little to no circulating blood sugar from food.
The keto diet includes high-fat foods such as meat, poultry, fish, eggs, cheese, nuts, seeds, and healthy oils like olive oil and coconut oil. Non-starchy vegetables are also recommended.
The keto diet has been shown to aid weight loss and increase energy levels. It has also been used to manage medical conditions such as diabetes, epilepsy, autoimmune disorders, and hormonal imbalances.
When transitioning to a keto diet, some people experience symptoms like headaches, nausea, fatigue, and muscle cramping, commonly known as the "keto flu." It can take several weeks for the body to adapt to burning fat instead of carbs.
