Cat nutrition is often treated as a simplified version of dog nutrition. In reality, however, cats have very different biological and nutritional requirements.
A cat is not a “small dog.” It is an obligate carnivore, with unique needs regarding protein, amino acids, fatty acids, vitamins, water intake, and feeding behavior. This means that general feeding rules commonly applied to dogs cannot automatically be transferred to cats.
Cats require high-quality animal protein and specific nutrients closely linked to their physiology. One of the best-known examples is taurine, an essential amino acid for cats. Inadequate taurine intake can significantly affect cardiac and ocular health, making sufficient taurine provision a critical aspect of feline diet formulation. FEDIAF guidelines include specific recommendations for complete cat foods and emphasize that feline nutritional requirements differ from those of dogs.
Another common misconception is the belief that cats naturally eat “only as much as they need.” In practice, many cats — especially indoor cats — may overconsume food when they have unrestricted access to dry food throughout the day. Obesity is one of the most common nutritional problems in cats and is influenced by food intake, activity level, neutering status, age, and feeding management. AAFP feline feeding guidelines highlight that cats prefer small, frequent meals in a secure environment, and that feeding practices influence both physical and behavioral health.
Food moisture content is also particularly important. Cats often have a naturally low thirst drive, so wet food may help increase total fluid intake. This can be especially beneficial for cats with a history of urinary tract issues or for animals requiring improved hydration as part of broader veterinary management. According to FEDIAF, wet food contains 60% moisture or more, whereas dry food has significantly lower moisture levels.
That does not mean wet food is always “good” and dry food is always “bad.” It means the overall nutritional plan must be assessed: whether the diet is complete and balanced, which life stage it is intended for, how many calories it provides, how much water the cat consumes, and whether there is any urinary, renal, or other relevant medical history.
Another frequently misunderstood issue is the relationship between dry food and dental health. The fact that a kibble is hard does not necessarily mean it effectively cleans teeth. Feline oral health requires regular assessment, veterinary monitoring, and targeted dental care. Food texture alone is not enough.
Home-prepared diets for cats also require special attention. Chicken, fish, liver, or “a little bit of everything” is not sufficient. Cats have increased requirements for specific nutrients such as taurine, calcium, phosphorus, vitamin A, arachidonic acid, and other micronutrients. FEDIAF notes that cats require more than 40 nutrients daily and stresses that homemade diets allow very little margin for error unless formulated by a qualified professional.
Fish is another classic example. Many cats strongly prefer it, but that does not mean it should form the basis of every meal. “They like it” does not always mean “it suits them” or “it is nutritionally complete.” Diets overly reliant on specific foods may lead to nutritional imbalances, particularly when not properly formulated.
A clinically important point is anorexia. A cat that is not eating is not simply being “picky” or “fussy.” Prolonged anorexia in cats is a serious warning sign that requires prompt veterinary evaluation, particularly in overweight cats or animals with underlying medical conditions.
At NutriVets, we do not approach feline nutrition through generic rules. We evaluate the individual animal, including age, body weight, body condition score, medical history, neutering status, urinary health, kidney function, dental status, medications, feeding behavior, and the actual goal of the nutritional intervention.
Proper feline nutrition is not about copying dog feeding principles. It is about individualized planning based on the physiology, needs, and medical history of each cat.
Book an appointment with NutriVets and create a personalized nutrition plan for your cat — built around its real needs, not generic advice.
