Why I Developed TCfeline Original
Can You Really Make Cat Food from Scratch? That is a question many people ask who see greater value in fresh, minimally processed foods than in highly processed convenience foods. If we believe food plays an important role in our own health, is it possible to feed our cats in a way that reflects those same values?
Can an ordinary person keep a feline companion happy and thriving with food they prepare themselves?
Yes, absolutely.
I asked the same question, and it ultimately shaped everything that followed. You have already taken the first steps on that same journey.
We recognised that cats are carnivores adapted to eating small prey. Naturally, we asked: Why not simply feed mice? It soon became clear that feeding mice every day presents practical, ethical, and financial challenges for most households.
The next logical step is prey-model raw feeding. It captures many of the principles of natural prey while making homemade feeding more accessible. Yet here, too, questions arise. How closely should meat, organs, and bone resemble a real prey animal? Which ratios are correct? How much variation is acceptable? Can we be certain that what works in theory will continue to support a cat through growth, adulthood, pregnancy, and old age?
Many people eventually arrive at the same conclusion I did: perhaps it is possible to prepare cat food from fresh ingredients with a recipe without having to reproduce an entire prey animal in every detail.
The next challenge is surprisingly ordinary. Preparing each batch means buying a long list of separate ingredients, crushing tablets, emptying capsules, and accurately measuring numerous powders. None of it is particularly difficult, but repeating the process every couple of weeks for years can become tedious.
Finding a simpler way to make homemade cat food became the beginning of TCfeline Original.
Rather than buying and measuring numerous individual supplements every time you prepare food, TCfeline Original brings them together in a single premix. Preparing homemade food becomes simpler, safer, more consistent, and more affordable while allowing you to remain in control of the ingredient that matters most: the meat.

How TCfeline Original is Different
What is a Prey-Model Raw Diet? Many households already feed their cats a prey-model raw diet without thinking of it that way, simply by allowing them access to the outdoors. The term “prey-model raw diet” is widely used within the raw feeding community by cat owners who prefer not to let their cats roam, but wish to feed them in a way that respects their biology as hunters and obligate carnivores.
There is no universally accepted definition of prey-model raw feeding. At its simplest, it describes a raw diet that uses the natural prey of wild cats as the biological and nutritional reference. Fresh, raw animal tissues should provide the overwhelming majority of nutrients, assembled to reproduce the nutritional composition of whole prey.

The objective is not simply to feed raw meat, but to recreate, as closely as practical, the nutritional characteristics of the whole prey a cat would naturally consume. This distinguishes prey-model feeding from diets that rely primarily on processed foods or nutrient standards developed independently of a cat’s evolutionary diet.
While the philosophy is widely shared among raw feeders, there is no single universally accepted method of putting it into practice. Today, three broad approaches are commonly found.
Whole-Prey Feeding
Whole-prey feeding provides intact prey animals such as mice, rats, rabbits, chicks or quail. Because the cat consumes the entire animal, this approach most closely reflects the natural feeding behaviour and diet of wild felines. For this reason, whole prey remains the biological benchmark against which other feeding methods are often compared.
Ratio-Based Prey-Model Feeding
Many raw feeders recreate whole prey by combining pieces of domestic meats according to predetermined proportions of muscle meat, edible bone, liver and other organs, and even attempt to include fur. This ratio-based prey-model feeding approximates the nutritional composition of prey by assembling anatomical proportions of individual animal parts.
Although this method follows the same biological philosophy as whole-prey feeding, it depends on obtaining a suitable selection of meats, bones and a variety of organs, and assumes that these ingredients collectively reproduce the nutritional qualities of natural prey.
Nutrient- and observation-calibrated prey-model feeding
A third approach begins with the same biological philosophy, but achieves that goal through nutritional formulation rather than anatomical imitation.
This is the approach used by TCfeline.
The development of TCfeline went beyond the anatomical examination of prey and the approximate reconstruction of its tissues with fresh domestic meats. It went a step further. Laboratory analyses of wild mice allowed individual nutrients to be calibrated more closely to natural prey. Long-term feeding observations involving generations of Feline Future study cats then further refined Feline Future’s feeding method to examine user-friendliness over long periods of time, acceptance by cats, digestibility and nutritional efficacy for all life stages.
Some ingredients remained unchanged because they closely reflected natural prey. Muscle meat, animal fat and liver remained fundamental throughout the development of the diet. Other components evolved in response to practical experience. Nutrients traditionally supplied by difficult-to-source organs and blood, such as iron, sodium and iodine are provided in a more practical form as supplements. Bone is supplied as MCHA to improve consistency of intake, maintain a reliable calcium to phosphorus ratio, increase bioavailability and improve safety without departing from the prey model. Although this may seem counterintuitive, finely ground bone may more closely reproduce the way small prey is naturally consumed than repeatedly feeding comparatively large poultry or rabbit bones. The later can lead to what we called here “chicken neck fatigue”, when cats begin avoiding chewing larger bones. Cats evolved eating the delicate skeletons of mice and small birds, not the much larger bones of domestic livestock.
TCfeline represents a distinct implementation of prey-model raw feeding—one that predates the later codification of ratio-based prey-model feeding and developed independently from the same biological principles. Throughout its evolution, the objective remained unchanged. Prey remained the nutritional blueprint. Three decades of feeding cats shaped the implementation.

Why You Can Trust This Approach
You only get one opportunity to support healthy pregnancy, normal development, and the healthy growth of a kitten. Those early decisions help lay the foundation for lifelong health while reducing the risk of some nutrition-related conditions that can affect cats later in life.
I understand what is at stake. That is why TCfeline Original was never released after just a short feeding trial or a laboratory calculation. It has been carefully formulated, continuously refined, and put to the test with all healthy life stages over and over again.
The formulation of TCfeline Original began with a simple question: What nutrients does a cat naturally obtain from its prey? The answer came from studying the composition of prey animals, sending real mice for nutritional analysis, and translating the results into a practical recipe using fresh meat. The nutrient composition of the finished recipe was then compared with well-established industry benchmarks, including the nutrient profiles developed by the Association of American Feed Control Officials (AAFCO) and the nutrient requirements established by the National Research Council (NRC).
Scientific formulation, however, is only the beginning. For decades, TCfeline Original has been continuously evaluated through the Feline Future study group.
Every refinement made to TCfeline Original over the years has been guided by observation, practical experience, and an ongoing commitment to understanding feline nutrition more deeply. Today, my confidence in TCfeline Original does not come from nutritional analyses or from meeting industry standards alone. It comes from watching this recipe support cats through every healthy stage of life—from growing kittens to active adults and through normal pregnancy and successful lactation whenever those stages formed part of the study. It is the formula I have trusted with every generation of my own cats, and I would never hesitate to feed it to the most vulnerable kitten, valuable breeding queen, or the most loved cat in my care.
