TL;DR
“Vet recommended cat food” is a marketing phrase, not a regulated certification. Any brand can use it. When vets genuinely recommend a food, they look for AAFCO nutritional adequacy, qualified nutritionist involvement, transparent ingredients, and appropriate moisture and protein levels. In Australia, where pet food standards are voluntary, understanding these terms yourself is the single best thing you can do for your cat.
The phrase “vet recommended” appears on cat food packaging everywhere. It sounds reassuring. It suggests clinical authority, scientific backing, maybe even a stamp of approval from a panel of white-coated professionals.
Here’s the problem: it means almost nothing.
There is no regulatory body in Australia, the US, or anywhere else that controls which brands can call themselves “vet recommended.” A company could pay a single veterinarian to endorse their product and technically claim veterinary recommendation in all their advertising. Some do exactly that.
This glossary exists to fix that gap. Instead of trusting a label, you’ll understand the actual terms, standards, and criteria that matter when choosing cat food. Every entry below explains what a term means, why it matters, and how to use it when evaluating any brand on the shelf or online.

The Terms That Actually Matter
AAFCO (Association of American Feed Control Officials)
AAFCO is a US-based organisation that sets nutritional and labelling standards for pet food. It does not test, approve, or certify any specific product. Instead, it establishes guidelines for ingredient definitions, nutrient profiles, label formatting, and feeding trial protocols. Pet food companies then use third-party testing to verify compliance.
Why should Australian cat owners care about an American body? Because Australia generally follows AAFCO (or FEDIAF, the European equivalent) requirements for pet food formulation. When you see “formulated to meet AAFCO nutrient profiles” on an Australian product, that’s the baseline standard the food is claiming to hit.
The key thing to remember: AAFCO compliance tells you a food clears a minimum nutritional bar. It won’t cause obvious deficiencies. But meeting AAFCO standards alone doesn’t tell you much about ingredient quality, manufacturing practices, or the depth of research behind the formula.
Complete and Balanced
This phrase appears on the AAFCO nutritional adequacy statement, which is one of the most important things on any cat food label. “Complete” means all required nutrients are present. “Balanced” means they’re present in the correct ratios to each other.
The statement also tells you which life stage the food is intended for: growth (kittens), adult maintenance, or all life stages. A food labelled “all life stages” must meet the more demanding kitten nutrition requirements, which means it works for adults too.
If a cat food doesn’t carry a nutritional adequacy statement, treat that as a red flag. It may be a treat, a topper, or a supplemental food, but it’s not designed to be your cat’s primary diet.
Formulated to Meet vs. Feeding Trials
This is a distinction most cat owners have never heard of, and it matters more than most brand names.
There are two ways a company can substantiate its AAFCO nutritional adequacy claim:
Formulated to meet AAFCO nutrient profiles means the manufacturer calculated that the recipe’s ingredients should, on paper, deliver the required nutrients. No animals were fed the food to verify this. It’s cheaper and faster, but it doesn’t account for how nutrients behave during processing or how a real cat’s body absorbs them. The nutrient content can be calculated from individual ingredients rather than tested in the finished product, which is less reliable since ingredients naturally vary and processing can alter nutrient availability.
Animal feeding trials means the company actually fed the food to cats following AAFCO protocols and documented their health outcomes. This is considered the gold standard because it proves the food works in practice, not just on a spreadsheet.
When evaluating vet recommended cat food, check which method was used. It’s printed right on the label, though you might need to look closely.
Obligate Carnivore
Cats are obligate carnivores. The word “obligate” is doing all the heavy lifting in that sentence. Some animals are facultative carnivores, meaning they prefer meat but can survive on plant-based nutrition when necessary. Dogs fall into this category. Cats cannot.
A cat’s metabolism is locked into patterns that depend on animal-sourced nutrients. They have a limited ability to synthesize certain amino acids (like taurine and arginine) from plant precursors. They require preformed vitamin A and arachidonic acid from animal tissue. Their livers maintain high levels of enzymes designed to process protein, regardless of how much protein they actually eat.
This is why protein content matters so much in cat food. Vet-recommended cat food typically contains at least 30 to 40% protein on a dry matter basis to maintain lean muscle and energy.
Taurine
Taurine is an amino acid that cats cannot produce in sufficient quantities on their own. It supports heart function, vision, digestion, immune response, and reproductive health. Without enough dietary taurine, cats risk developing dilated cardiomyopathy (DCM), a condition where the heart enlarges and weakens. Cats can experience early stages of DCM without showing obvious symptoms until significant damage has occurred.
The richest natural sources of taurine are muscle meat, fish, and organ meats like liver and heart. This is one reason why the protein source in cat food matters, not just the protein percentage. A food built around real meat will generally deliver more bioavailable taurine than one padded with plant proteins.
Human-Grade
By AAFCO’s definition, a human-grade pet food must be made with 100% human-edible ingredients and manufactured, packed, and stored in facilities approved for human food production. The claim has to apply to the entire finished product, not just one ingredient. So “made with human-grade chicken” is not the same as “human-grade cat food.”
In Australia, there is no single official legal definition of human-grade pet food. The PFIAA (Pet Food Industry Association of Australia) explains that the term is generally used when all ingredients come from the human food supply chain and the food is processed in certified human-food facilities. Importantly, a human-grade claim cannot infer that the product is inherently safer just by virtue of its sourcing or manufacturing standards.
For a deeper look at what this label means in practice, read our human-grade cat food guide.
Feed-Grade vs. Human-Grade
Most pet food sold in Australia and globally is feed-grade, meaning it doesn’t meet the standards required for human consumption. The gap between these two categories is larger than most people realise.
An abattoir slaughters and processes meat fit for human consumption. A knackery slaughters and processes meat intended for animal food. Some knackery meat may come from animals that died or were killed before arriving at the facility. Feed-grade ingredients can include parts and products that would never pass human food safety inspection.
Human-grade cat food is growing in popularity precisely because owners want to know their cat’s food meets a higher baseline. For more on what goes into human-grade ingredients, see our ingredients guide.
WSAVA Guidelines
The World Small Animal Veterinary Association publishes guidelines that focus not on the food itself but on the company making it. Their framework asks whether the manufacturer employs board-certified veterinary nutritionists, conducts feeding trials, performs quality control testing, and publishes peer-reviewed research.
A critical point: WSAVA does not officially approve or certify pet food brands. They provide a set of questions for pet owners to ask manufacturers. When someone says a food is “WSAVA approved,” that’s a misuse of the term. What they usually mean is that the brand meets most or all of the WSAVA criteria.
There’s a tension worth knowing about. WSAVA’s Global Nutrition Committee is financially supported by the Purina Institute, Hill’s Pet Nutrition, and Royal Canin. This doesn’t invalidate their guidelines, but it explains why the same three or four brands tend to dominate “vet recommended” lists, and why some pet owners are sceptical.
An Australian vet nurse who specialises in nutrition encourages cat owners to investigate their pet food company using the WSAVA framework, specifically checking who formulated the recipes and whether they have advanced qualifications.
AS5812 (Australian Standard for Pet Food)
AS5812:2017 is a technical document that sets requirements for pet food production, ingredient sourcing, processing, heat treatment, labelling, storage, and recall procedures.
The catch: it’s voluntary. To make it mandatory would require legislative change and the establishment of a regulatory body to enforce compliance. If a food is found not to comply, no authority can currently enforce consequences.
South Australia is leading reform. Recent legislation aims to make AS5812:2023 (an updated version developed with input from PFIAA, the Australian Veterinary Association, and other stakeholders) mandatory, at least within that state. For the rest of Australia, compliance remains a choice.
PFIAA (Pet Food Industry Association of Australia)
The PFIAA is the industry body for pet food in Australia. It developed AS5812 alongside the AVA and others. However, the PFIAA is not a regulatory body and holds no legal power to enforce anything. This is a point that catches many Australian cat owners off guard: the organisation that writes the rules cannot make anyone follow them.
This gap is exactly why learning to read labels and ask the right questions matters more in Australia than in countries with mandatory pet food regulation.
Prescription Diet (Veterinary Therapeutic Diet)
Prescription diets are formulated to manage specific medical conditions like kidney disease, diabetes, food intolerances, or urinary tract problems. They are not the same as general vet recommended cat food for healthy cats. These diets adjust nutrient levels in ways that would be inappropriate for a cat without the targeted condition.
Only feed your cat a prescription or therapeutic diet if your vet specifically instructs you to do so. The best cat food for one cat may be completely wrong for another.
If your vet has recommended a diet change, here’s how to transition your cat safely.
Moisture Content (Wet, Dry, Fresh)
The moisture differences between cat food formats are dramatic. Dry food (kibble) contains roughly 10% moisture. Wet food (canned or pouched) contains 70 to 80%. Fresh, gently cooked food sits in a similar range to wet food.
This matters because cats are descended from desert-dwelling ancestors and have a naturally low thirst drive. They’re designed to get most of their water from food, not from a bowl. Research from the WALTHAM Petcare Science Institute demonstrated that a high-moisture diet boosts a cat’s total daily water intake to levels that cannot be achieved simply by providing drinking water alongside dry food. The higher water intake produced more dilute urine, which is protective for urinary health.
The American Animal Hospital Association notes that while preventing feline lower urinary tract diseases involves multiple factors, a high-moisture diet helps dilute urine and increase urination frequency, making the urinary tract less hospitable to crystal formation.
Practitioners on Reddit’s r/catfood community consistently favour wet and fresh formats over kibble for this reason, with many citing visible improvements in hydration and coat quality after switching.

Life Stage Labelling (Kitten, Adult, Senior, All Life Stages)
Cat food labels specify which life stage the product is designed for, and this matters because nutritional needs change significantly over a cat’s life.
Kitten formulas need higher protein, more calories, DHA for brain development, and carefully balanced calcium-to-phosphorus ratios. Adult formulas focus on maintenance-level protein and calories with an emphasis on preserving lean muscle mass. Senior formulas often include joint support ingredients, kidney-friendly mineral levels, and highly digestible protein sources.
An “all life stages” formula must meet the most demanding nutritional profile (growth/reproduction), which means it’s nutritionally adequate for kittens, adults, and seniors alike. This is the standard Pikko’s recipes are formulated to.

Gently Cooked / Fresh Cat Food
Gently cooked cat food is heated enough to kill harmful pathogens but at lower temperatures than traditional kibble manufacturing, which helps preserve more nutrients. This positions it between raw food (uncooked) and kibble (heavily processed at high heat).
The raw food question comes up constantly in discussions about vet recommended cat food. Cornell University states plainly that raw meat is not recommended as food or a treat for cats because it’s a potential vehicle for toxoplasmosis and other infectious diseases. Both the American Veterinary Medical Association and the American Animal Hospital Association discourage feeding raw cat food due to the risk of bacterial contamination.
Gently cooked food addresses these safety concerns while avoiding the extreme processing of kibble. For a detailed comparison, see our article on fresh vs raw cat food safety.
By-Products
Ingredients like chicken by-product meal and whole grain corn are often treated as villains in online pet food discussions. The reality is more nuanced. By-products can include organ meats (liver, heart, kidneys) that are genuinely nutritious for cats. They can also include less desirable parts.
The term itself doesn’t tell you enough about the overall nutritional value or quality of a food. What matters more is the company’s transparency about exactly which by-products are used, the overall nutrient profile of the finished food, and whether the formulation was done by a qualified nutritionist.
FLUTD (Feline Lower Urinary Tract Disease)
Feline lower urinary tract disease is a group of conditions affecting the bladder and urethra. It’s a significant concern for cats, especially males, and affects up to 8% of cats at some point in their lives.
Vet recommended cat food for urinary tract support aims to maintain proper urine pH levels and encourage dilute urine to prevent crystal and stone formation. This is where moisture content becomes clinically important, not just a preference. High-moisture diets produce more dilute urine, which directly reduces the conditions that lead to crystal formation.
Do Vets Get Kickbacks for Recommending Cat Food?
This question comes up in nearly every online discussion about vet recommended cat food. It deserves a direct answer.
Veterinarians do not receive commissions or kickbacks for recommending specific food brands. As one veterinary professional explained in a practitioner forum, prescription diets are far from a money-maker for clinics. The markup is small. Clinics stock therapeutic foods so the appropriate diet is available when they recommend it, not because it’s profitable.
The reason vets tend to recommend the same handful of brands (Hill’s, Royal Canin, Purina Pro Plan) is straightforward: these companies employ board-certified veterinary nutritionists, conduct feeding trials, perform quality control testing, and publish peer-reviewed research. There are only about 96 veterinarians board-certified by the American College of Veterinary Nutrition, and a disproportionate number work for these large companies. That’s a staffing reality, not a conspiracy.
That said, veterinarians are not monolithic. They don’t all agree on nutrition. Some don’t even recommend foods that carry “vet recommended” on the label. The important takeaway is that the WSAVA criteria (qualified formulator, AAFCO compliance, quality control, transparency) can be met by smaller brands that invest in proper nutrition science. A nutritionist-formulated, AAFCO-compliant food with clear ingredient panels is doing what the science asks for, regardless of the company’s marketing budget.
How to Evaluate Any Cat Food Like a Vet Would
Instead of relying on the phrase “vet recommended,” use this checklist adapted from the WSAVA framework for Australian cat owners:
-
Does the company employ a qualified nutritionist? Look for a board-certified veterinary nutritionist or someone with equivalent advanced qualifications who formulated or reviewed the recipes.
-
Is there an AAFCO or FEDIAF nutritional adequacy statement on the label? If not, the food may not be complete and balanced.
-
Was the food validated through feeding trials or formulated to meet profiles? Feeding trials are preferred, but formulation by a qualified professional is a reasonable standard for smaller manufacturers.
-
Can the company provide a full nutrient analysis? Not just guaranteed analysis minimums, but a detailed typical analysis. Transparency here signals confidence in the product.
-
What quality control and food safety measures are in place? Does the company test for contaminants? Do they control their own manufacturing, or outsource it?
-
Is the company transparent about ingredient sourcing? Can they tell you where their meat comes from and what grade it is?
A food that passes these six questions is doing what genuinely vet recommended cat food should do, whether or not it carries that phrase on the packaging.
Why This Matters Even More in Australia
Australia’s pet food industry operates in a regulatory environment that places unusual responsibility on the consumer. The national standard for pet food (AS5812) is voluntary. PFIAA has no legal enforcement powers. As Bronwyn Orr from RSPCA Australia has pointed out, pet food companies aren’t under any legal obligation to initiate a recall.
The consequences of this gap have been tragic. A contamination event in Victoria left at least 67 dogs seriously ill and 23 dead, highlighting the lack of consumer protection. A longstanding problem in Australian pet food has been the use of sulphite preservatives, which keep meat looking red and fresh but deplete thiamine. Cats fed exclusively on thiamine-deficient meat can develop neurological problems that cause death.
Australia also lacks dedicated pet food research facilities for feeding trials or a domestic veterinary nutrition specialty service. This means Australian brands typically rely on overseas AAFCO or FEDIAF frameworks rather than local validation infrastructure.
All of this makes label literacy, ingredient transparency, and the checklist above not just helpful but essential for Australian cat owners. If you’re looking for cat food without preservatives, that’s a reasonable starting point given these risks.
Putting It All Together
The phrase “vet recommended cat food” will keep appearing on packaging because it works as marketing. The best defence against misleading claims is knowing what the terms actually mean.
A food worth feeding your cat should carry an AAFCO nutritional adequacy statement. It should be formulated by someone with genuine nutrition qualifications. The company should be willing to share its full ingredient list, nutrient analysis, and sourcing practices. And for most cats, especially those prone to urinary issues or those eating primarily dry food, increasing moisture content is one of the most impactful changes you can make.
These aren’t controversial positions. They’re the criteria that informed veterinarians use when they recommend food, regardless of what’s printed on the front of the bag.
If you’re ready to try a fresh, gently cooked option that meets these standards, start with Pikko’s trial box, which is nutritionist-formulated, AAFCO-compliant for all life stages, and made from 100% human-grade Australian meat.
Frequently Asked Questions
Is “vet recommended” cat food regulated in Australia?
No. There is no regulatory body in Australia that controls the use of “vet recommended,” “vet approved,” or similar phrases on pet food packaging. Any brand can use these terms. The Australian Standard AS5812 covers manufacturing and labelling requirements, but it is voluntary and unenforceable.
What should I look for instead of a “vet recommended” label?
Look for an AAFCO or FEDIAF nutritional adequacy statement confirming the food is complete and balanced. Check whether a qualified nutritionist formulated the recipes. Review the ingredient list for named protein sources and transparency about sourcing. These are the criteria vets actually use when evaluating food.
Why do vets always recommend the same brands?
Brands like Hill’s, Royal Canin, and Purina employ board-certified veterinary nutritionists, conduct feeding trials, and publish peer-reviewed research. Vets are trained to anchor recommendations in foods with this level of scientific backing. However, smaller brands that meet the same WSAVA criteria (qualified formulation, AAFCO compliance, quality control, transparency) can be equally trustworthy.
What does “complete and balanced” mean on cat food?
“Complete” means the food contains all nutrients a cat requires. “Balanced” means those nutrients are present in the correct ratios. The label should also specify which life stage (growth, maintenance, or all life stages) the food is designed for. Without this statement, a product may be a treat or supplement rather than a full diet.
Is wet food really better than dry food for cats?
Research shows that high-moisture diets increase total water intake to levels dry food plus a water bowl cannot achieve. For cats prone to urinary tract issues, this is clinically significant. Wet and fresh foods also tend to be higher in protein and lower in carbohydrates than most dry foods. Vets frequently recommend increased moisture, particularly for cats with FLUTD risk factors.
What is the difference between “formulated to meet” and “feeding trials”?
“Formulated to meet” means the recipe was calculated to deliver required nutrients on paper, without being tested on actual cats. “Feeding trials” means cats were fed the food as their sole diet under AAFCO protocols, and their health was monitored. Feeding trials are considered the gold standard because they verify the food works in practice.
Are by-products in cat food bad?
Not necessarily. By-products can include nutrient-rich organ meats like liver and heart, which are excellent sources of taurine. The issue is when the term is used vaguely to obscure low-quality ingredients. Look for named by-products (e.g., “chicken liver”) rather than generic “animal by-products,” and prioritise brands that are transparent about what’s included.
How is Australian pet food regulation different from the US?
The US has mandatory federal oversight through the FDA and state-level enforcement guided by AAFCO standards. Australia’s pet food standard (AS5812) is voluntary, with no regulatory body empowered to enforce compliance or mandate recalls. South Australia is the first state moving toward mandatory standards, but the rest of the country currently relies on industry self-regulation.
