In February 2025, two unusual dog-food launches appeared within three weeks of each other.
The first was Chick Bites, a limited-edition dog treat sold in the United Kingdom and containing chicken grown from animal cells.
The second was MicroBell, a complete vegan dry dog food containing a protein produced by fermenting microorganisms without using animals or agricultural crops.
Both were described through language such as:
- Cultured protein
- Fermentation
- Cellular agriculture
- Animal-free protein
- Bioreactor production
- Sustainable pet nutrition
But they were not the same technology.
Chick Bites contained cultivated meat.
MicroBell contained microbial protein.
That distinction matters because cultivated meat and fermentation-derived protein begin with completely different biological systems.
One grows animal cells.
The other grows microorganisms.
A year later, FORZA10 and BeneMeat introduced Coolty Meat, a complete wet dog food containing 26% cultivated meat and described by its developers as the first complete cultivated-meat dog food commercially launched in the European Union.
The category therefore did not experience one simple "first."
It experienced three:
- The first commercial pet product containing cultivated meat
- The first complete dog food containing FeedKind fermented microbial protein
- The first complete cultivated-meat dog food launched in the EU
This is one signal from the Consensys Innovation Signals Engine, which continuously scans a library of more than one million products worldwide for emerging shifts in formulation, positioning and consumer demand.
Signal: Alternative Proteins Splitting Into Distinct Commercial Categories
The original claim combines two different technologies
The original research row describes Calysta and Marsapet's FeedKind Pet product as the first commercially available dog food made with lab-grown meat.
That is incorrect.
Calysta describes FeedKind as a protein created by controlled fermentation of naturally occurring microorganisms.
The ingredient does not consist of chicken, beef or other animal cells.
It is a single-cell protein produced by growing bacteria in a controlled fermentation system. Calysta says the process uses no animal-derived ingredients, no plant ingredients and no agricultural land.
Technology: Microbial fermentation
Biological input: Naturally occurring microorganisms
Final ingredient: Concentrated microbial protein
Animal cells: None
Cultivated meat: No
Evidence Correction: FeedKind Is Fermented Microbial Protein, Not Lab-Grown Meat
Calling FeedKind cultivated meat would be like calling yeast protein cultivated chicken because both are grown inside fermentation equipment.
The production hardware can look similar.
The biology is fundamentally different.
What is cultivated meat?
Cultivated meat is produced by growing animal cells outside the animal.
A developer typically begins with cells obtained from an animal source, then supplies those cells with:
- Nutrients
- Amino acids
- Vitamins
- Minerals
- Energy sources
- Controlled temperature and oxygen conditions
The cells multiply inside a bioreactor and produce animal-cell biomass.
The resulting material is biologically animal tissue or animal-cell material, even though the animal itself was not raised and slaughtered in the conventional way.
Innovation Type: Animal-Cell Agriculture
Cultivated chicken begins with chicken cells.
Cultivated beef begins with cattle cells.
The central promise is:
Produce animal meat while substantially reducing the need to breed, house and slaughter livestock.
What is microbial protein?
Microbial protein is produced by growing microorganisms such as:
- Bacteria
- Yeasts
- Fungi
- Microalgae
The microorganisms themselves become the source of protein.
Calysta's FeedKind process uses a naturally occurring bacterium, commonly identified in its scientific research as Methylococcus capsulatus, which is grown through controlled fermentation.
After growth and processing, the resulting ingredient contains concentrated protein, fat and other cellular components.
Innovation Type: Single-Cell Protein Fermentation
The central promise is different:
Create nutritionally useful protein without growing animals or conventional protein crops.
FeedKind is therefore closer conceptually to:
- Yeast protein
- Mycoprotein
- Algal protein
- Other biomass-fermentation ingredients
than to cultivated chicken.
FeedKind may actually be more radical than cultivated meat in one respect
Cultivated meat still begins with animal cells.
FeedKind does not.
Calysta says its process requires:
- No animal ingredients
- No plant ingredients
- No arable land
- Very little water
The microorganisms are supplied with a carbon and energy source inside a patented fermentation system. The resulting biomass is harvested as a high-protein feed ingredient.
Innovation Type: Agriculture-Independent Protein Production
This means FeedKind does not need:
- Livestock farming
- Soy fields
- Pea fields
- Fishmeal
- Meat by-products
The process creates protein through industrial biology rather than agriculture.
MicroBell was the first complete dog food using FeedKind Pet
On February 27, 2025, Calysta and German pet-food company Marsapet announced MicroBell, sold through Marsapet's Marsavet veterinary-health line.
The companies described it as the first complete dog food containing FeedKind Pet protein.
The dry kibble was formulated as:
- Vegan
- Grain-free
- Gluten-free
- Nutritionally complete
Its main ingredients were described as:
- Sweet potato
- Peas
- FeedKind protein
- Potato
Calysta said the product contained the amino acids required to support a complete canine diet.
Brand: Marsavet
Product: MicroBell
Pet-food company: Marsapet
Protein partner: Calysta
Launch: February 27, 2025
Innovation Type: First Complete FeedKind-Based Dog Food
That is a genuine commercial first.
It simply is not a cultivated-meat first.
FeedKind had already appeared in dog treats
MicroBell was not the first pet product to use FeedKind.
In May 2024, Dr. Clauder's introduced an air-dried dog treat containing FeedKind Pet at Interzoo.
Calysta described it as the first dog treat made with the ingredient.
The commercial progression was therefore:
May 2024
First FeedKind-based dog treat announced.
August 2024
First major commercial shipment of FeedKind Pet arrived in Europe.
February 2025
First complete dog food containing FeedKind Pet launched.
Market Signal: Ingredient Moving From Demonstration to Daily Diet
Treats are a useful first commercial format because they represent a small proportion of total nutrition.
A complete food carries a much higher burden.
It must supply all nutrients required for the intended life stage when fed as the animal's primary diet.
Meatly reached the market first with actual cultivated meat
On February 7, 2025, British cultivated-meat company Meatly, dog-food brand The Pack and retailer Pets at Home began selling Chick Bites.
The treats combined:
- Plant-based ingredients
- Cultivated chicken produced by Meatly
The initial release was limited to one Pets at Home store in Brentford, England. The companies described it as the world's first commercial pet-food product containing cultivated meat.
Brand: The Pack
Product: Chick Bites
Cultivated-meat producer: Meatly
Launch: February 7, 2025
Format: Dog treat
Commercial scale: Limited single-store release
Innovation Type: First Retail Cultivated-Meat Pet Treat
This launch preceded MicroBell by approximately three weeks.
But the products occupied different categories:
Chick Bites was a treat containing cultivated animal cells.
MicroBell was a complete diet containing fermentation-derived microbial protein.
Meatly's chicken came from animal cells
Meatly said its cultivated chicken began with cells derived from a chicken egg.
The cells were grown with nutrients inside a controlled production system, creating chicken-cell biomass without repeatedly raising and slaughtering chickens.
The company claimed the ingredient contained amino acids, fatty acids, vitamins and minerals associated with chicken meat.
The important distinction is not whether the product was grown in a vessel.
Both cultivated cells and microorganisms can be grown in vessels.
The distinction is what is being grown:
- Technology
- Organism being grown
- Result
- Cultivated meat
- Animal cells
- Animal-cell biomass
- FeedKind fermentation
- Microorganisms
- Microbial protein biomass
- Precision fermentation
- Engineered microbes producing a target molecule
- Specific protein, fat or compound
- Plant agriculture
- Crops
- Plant ingredients
- Consumer Education Signal: "Fermented" Does Not Automatically Mean "Cultivated Meat"
- Chick Bites was not a complete dog food
The initial Meatly launch was a treat.
The companies did not present Chick Bites as a product capable of supplying a dog's entire daily nutritional requirements.
That limitation matters when discussing "firsts."
A treat proves:
- Regulatory acceptance
- Ingredient production
- Palatability
- Retail feasibility
- Consumer curiosity
A complete food must additionally prove:
- Nutritional adequacy
- Safe inclusion levels
- Digestibility
- Long-term feeding suitability
- Consistent manufacturing
- Evidence Distinction: First Treat Versus First Complete Diet
- FORZA10 introduced a true complete cultivated-meat dog food
In May 2026, Italian pet-food brand FORZA10 introduced Coolty Meat at Interzoo in Nuremberg.
The wet dog food was developed with cultivated-meat technology company BeneMeat and contained 26% cultivated meat, according to company and trade-industry reporting.
It also contained ingredients including:
- Vegetables
- Pea protein
- Brewers' yeast
The companies presented the product as nutritionally complete and suitable for regular feeding.
Brand: Coolty Meat / FORZA10
Cultivated-meat supplier: BeneMeat
Launch: May 2026
Format: Complete wet dog food
Cultivated-meat inclusion: 26%
Innovation Type: Complete Cultivated-Meat Pet Nutrition
This is much closer to the headline originally proposed.
A corrected version would be:
- The First Complete Cultivated-Meat Dog Food Has Reached the European Market
- FORZA10's "first" is still a company claim
Trade publications consistently describe Coolty Meat as the first commercial launch of a complete cultivated-meat dog food in the EU.
The wording should remain attributed to the companies because "first" claims can depend on:
- Geographic scope
- Definition of commercial availability
- Whether the product is a treat or complete food
- Whether a trade-show launch counts as full retail availability
- Distribution scale
- Whether the UK is included within "Europe" or separated from the EU
BeneMeat's own material describes the product as the first complete dog food of its kind to reach the European market.
Evidence Signal: Strongly Documented Company First Claim
Evidence Gap: Initial Retail Scale and Availability Require Continued Verification
The EU and Europe are not interchangeable
The UK approved Meatly's cultivated chicken for pet-food use in July 2024 and hosted the first commercial cultivated-meat pet treat in February 2025.
The UK is geographically European but is no longer part of the European Union.
BeneMeat became the first company to register cultivated-meat pet-food material in the EU feed-material system in 2023.
The sequence is therefore:
United Kingdom
First European regulatory approval and first commercial pet treat containing cultivated meat.
European Union
First registered cultivated-meat pet-food material, followed by the claimed first complete commercial product.
Database Correction: Separate UK, Europe and EU Claims
BeneMeat uses animal cells; FeedKind does not
The two technologies can now be compared clearly.
FeedKind Pet
Grows naturally occurring microorganisms
Does not use animal cells
Produces single-cell protein
Can support vegan product positioning
Uses fermentation as the primary production method
BeneMeat cultivated meat
Grows animal cells
Produces animal-cell biomass
Is meat biologically, despite avoiding conventional livestock production
Cannot accurately be described as vegan
Uses cell-culture technology
Trust Distinction: Animal-Free Protein Versus Slaughter-Free Animal Protein
Both may reduce reliance on conventional livestock.
Only one is actual meat.
"Cultured protein" is technically broad but commercially confusing
Calysta describes FeedKind as cultured protein.
That wording is technically defensible because the microorganisms are cultured.
But consumers increasingly associate "cultured" with:
- Cultured meat
- Cell-cultivated chicken
- Lab-grown beef
Using the same term across microbial biomass and animal-cell cultivation can create confusion.
Risk Signal: Shared Language Across Different Technologies
A clearer classification system would use:
- Microbial protein
- Fermentation-derived protein
- Single-cell protein
for FeedKind, and:
- Cultivated meat
- Cell-cultured meat
- Animal-cell biomass
for Meatly and BeneMeat.
Dogs need nutrients, not a culturally defined meat ingredient
A dog's nutritional requirement is not for a named ingredient such as chicken breast.
It is for an appropriate balance of:
- Essential amino acids
- Fatty acids
- Vitamins
- Minerals
- Energy
- Fibre
- Other nutrients
A complete diet can theoretically use different ingredient systems if the finished formulation meets the animal's nutritional requirements and is digestible, safe and palatable.
Nutrition Signal: Biological Requirement Is Nutrient-Based
This makes pet food a potentially attractive early market for alternative proteins.
The ingredient does not need to recreate the visual structure of a steak.
It may be processed into:
- Kibble
- Wet food
- Treats
- Toppers
- Nutritional pastes
Texture replication is less demanding than in cultivated meat intended for a human restaurant.
FeedKind now has published dog-safety data
A 2025 peer-reviewed study evaluated FeedKind Pet in adult dogs.
Thirty-two healthy adult beagles received diets containing up to 8% FeedKind protein during a six-month feeding period, followed by a two-month control period.
The researchers assessed:
- General health
- Body weight
- Feed intake
- Digestibility
- Blood and clinical measures
- Faecal microbiome effects
The study reported that the ingredient was well tolerated at the tested inclusion levels.
Protein and energy digestibility exceeded 80%, while fat digestibility exceeded 90%. The dogs maintained normal weight and body-condition measures, and the study reported microbiome changes that the researchers considered potentially beneficial.
Evidence Signal: Six-Month Target-Animal Safety Study
Evidence Limitation: One Ingredient Study Does Not Validate Every Final Product
The findings support FeedKind as an ingredient.
They do not automatically prove that every formula containing it is nutritionally complete.
The FeedKind study had commercial involvement
The research concerns a proprietary Calysta ingredient and was connected to the company's regulatory and commercial development programme.
That does not make the results invalid.
It does mean the evidence should be interpreted with:
- Funding disclosure
- Author-affiliation review
- Attention to study design
- Independent replication
Evidence Principle: Peer Review Strengthens the Claim; Independent Replication Strengthens It Further
The study involved healthy adult dogs.
It does not automatically establish suitability for:
- Puppies
- Pregnant dogs
- Dogs with kidney disease
- Dogs with food allergies
- Every breed
- Lifelong exclusive feeding at every inclusion level
- FeedKind has a complete amino-acid profile—but the finished diet still matters
Calysta describes FeedKind Pet as having a complete amino-acid profile and sufficient nutritional density to support complete pet-food formulations.
The ingredient contains high levels of crude protein and some fat.
But dogs do not eat isolated protein in real life.
The complete formula must balance:
- Protein quality
- Total amino-acid supply
- Fatty acids
- Calcium and phosphorus
- Vitamins
- Trace minerals
- Energy density
- Fibre
- Palatability
- Evidence Correction: Protein Equivalence Is Not Complete-Diet Equivalence
A nutritionally strong protein ingredient can still be used inside a poorly formulated diet.
Cultivated meat also needs complete nutritional characterisation
BeneMeat presents its cultivated material as a nutritious source of animal protein.
The ingredient must still be characterised for:
- Amino-acid composition
- Fat profile
- Vitamins
- Minerals
- Nucleic-acid content
- Digestibility
- Processing stability
- Microbiological safety
- Batch consistency
Cultivated meat may resemble conventional meat biologically.
It is not automatically nutritionally identical.
Differences can emerge from:
- Cell line
- Growth medium
- Harvest stage
- Processing
- Added nutrients
- Fat-cell content
- Moisture
- Final inclusion rate
- Evidence Gap: Product-Specific Nutritional Equivalence Requires Direct Measurement
- "No arable land" applies to FeedKind's core fermentation—not necessarily every input
Calysta says FeedKind production uses no agricultural land because the microorganisms are not fed crops such as soy, wheat or peas.
That is a meaningful distinction.
However, a complete lifecycle assessment must consider the sources of:
- Energy
- Carbon feedstock
- Nitrogen
- Minerals
- Fermentation equipment
- Processing
- Drying
- Transport
The Carbon Trust previously assessed FeedKind's environmental footprint and reported substantially lower water use than several conventional protein ingredients, along with very low agricultural-land requirements.
Evidence Signal: Strong Land-Use Advantage
Evidence Limitation: "No Arable Land" Is Not the Same as "No Environmental Footprint"
Fermentation remains an industrial process requiring energy and infrastructure.
Methane-derived protein raises a different sustainability question
FeedKind's process has historically used methane or natural gas as a carbon and energy source for methane-consuming bacteria.
This avoids agricultural land but creates questions about:
- Fossil versus renewable methane
- Methane leakage
- Energy source
- Carbon intensity
- Facility location
- Process efficiency
- Sustainability Trade-Off: Land Independence Versus Carbon-Source Dependence
The environmental result can vary substantially depending on whether the methane comes from:
- Fossil natural gas
- Biogas
- Captured waste methane
- A lower-carbon industrial source
The strongest future version of the technology may pair microbial fermentation with renewable or waste-derived carbon.
FeedKind is already operating at industrial scale
Calysta and Adisseo developed the Calysseo production facility in Chongqing, China.
Calysta described the initial facility as capable of producing approximately 20,000 tonnes of FeedKind protein annually.
By 2024, commercial tonnes of FeedKind Pet were being shipped from the facility to Europe through a warehouse in Poland.
Scale Signal: Tens of Thousands of Tonnes of Fermentation Capacity
That places FeedKind in a different commercial position from many cultivated-meat companies.
Cultivated meat remains constrained by:
- Cell-culture-media cost
- Bioreactor productivity
- Sterility
- Scale-up
- Capital requirements
- Regulatory approval
FeedKind's microbial process is closer to established industrial fermentation.
The 20,000-tonne figure is not necessarily all available for pet food
The Chongqing facility was initially built primarily around aquaculture-feed applications.
FeedKind Pet uses the same broad protein platform, but public materials do not establish that the full 20,000-tonne annual capacity is dedicated to companion-animal food.
The responsible wording is:
Calysta has access to industrial-scale FeedKind production capacity, while the exact current volume allocated to pet-food customers is not publicly disclosed.
Evidence Gap: Pet-Specific Production Volume and Unit Economics Not Public
This is central to the original research recommendation.
Commercial-scale fermentation does not automatically reveal:
- Ingredient price per kilogram
- Minimum order volume
- Cost relative to chicken meal
- Cost relative to soy protein
- Cost after transport
- Margin in finished dog food
- Cultivated meat remains much more constrained by economics
Meatly's Chick Bites launch was intentionally limited.
The product was sold at one store, and Meatly said wider availability would depend on scaling production over the following years.
This illustrates the category's central economic challenge.
A product can be:
- Technically feasible
- Approved
- Nutritionally promising
- Commercially launched
without being available at mass-market volume or price.
Market Signal: Commercial Launch Does Not Equal Commercial Scale
FORZA10's 2026 launch represents another important step, but the initial distribution scale and unit economics remain unclear.
Pet food may be the fastest route to cultivated-meat scale
The economics of pet food differ from human meat.
Pet products can use cultivated biomass as:
- A minority inclusion
- A protein component
- A palatability enhancer
- A functional ingredient
- Part of a blended formula
The product does not need to recreate:
- Muscle fibres
- Marbling
- Steak structure
- Human culinary texture
- Innovation Advantage: Biomass Is Valuable Without Whole-Cut Structure
That could allow cultivated-meat companies to reach commercial relevance in pet food earlier than in mainstream human meat.
A 26% inclusion level is commercially significant
Coolty Meat reportedly contains 26% cultivated meat.
That is much more substantial than using a trace amount simply to support a futuristic claim.
At the same time, the product is still a blended food containing plant and fermentation-derived ingredients.
Commercial Signal: Cultivated Protein as Major Ingredient, Not Entire Formula
The formulation demonstrates how early cultivated-meat products are likely to develop:
Cultivated cells + conventional nutrients + plant ingredients + functional processing components
rather than 100% cultivated meat.
Alternative protein may be especially useful for food intolerance
FORZA10 has associated Coolty Meat with a monoprotein positioning and dogs with food sensitivities.
A novel protein source could theoretically be useful when a dog has previously been exposed to common proteins such as:
- Chicken
- Beef
- Lamb
However, cultivated meat still originates from an animal species.
A dog allergic to a conventional species protein may potentially react to related proteins from cultivated cells.
Risk Signal: Novel Production Method Does Not Automatically Mean Hypoallergenic
Any food-intolerance or allergy positioning requires product-specific veterinary evidence.
"Slaughter-free" is more accurate than "animal-free" for cultivated meat
Cultivated meat may dramatically reduce the number of animals required.
But animal cells are still part of the production origin.
Depending on the company and process, animal-derived components may also be relevant to:
- Initial cell sourcing
- Cell banking
- Growth media
- Research stages
Modern cultivated-meat companies increasingly aim to avoid fetal bovine serum and other animal-derived growth inputs.
BeneMeat describes its approach as designed around scalable, serum-free production, but complete technical details remain proprietary.
Evidence Correction: Cultivated Meat Is Not Necessarily Animal-Free
FeedKind can support a vegan claim.
Cultivated meat generally supports a slaughter-reduction claim.
The environmental case must be tested at commercial scale
BeneMeat says it has completed a peer-reviewed lifecycle assessment indicating reduced land use and emissions compared with conventional animal protein.
Cultivated-meat sustainability depends heavily on:
- Energy source
- Bioreactor efficiency
- Growth-medium ingredients
- Facility scale
- Cooling and sterilisation
- Cell density
- Product yield
A small efficient pilot does not guarantee the same impact at large scale.
Evidence Signal: Early Lifecycle Evidence
Evidence Gap: Independently Replicated Commercial-Scale Footprint
The same caution applies to fermentation protein.
Alternative does not automatically mean lower impact under every production scenario.
Consumer acceptance may depend on terminology
Pet owners may react differently to the terms:
- Lab-grown meat
- Cultivated meat
- Cell-cultured chicken
- Fermented protein
- Microbial protein
- Single-cell protein
"Lab-grown" communicates novelty but may create concern.
"Fermented" feels familiar but may obscure the underlying organism.
"Cultivated meat" is more precise for animal-cell products.
Consumer Psychology Signal: Technology Name Shapes Trust
Brands will need to explain:
- What is being grown
- What the finished ingredient contains
- Why it is safe
- How it is nutritionally evaluated
- Whether animals are involved
- Why the process is environmentally different
- Veterinary confidence will require more than sustainability claims
Pet owners may like the environmental proposition.
Veterinarians will focus on:
- Nutritional adequacy
- Digestibility
- Palatability
- Long-term safety
- Manufacturing quality
- Contaminant controls
- Life-stage suitability
- Clinical outcomes
- Trust Mechanism: Veterinary Nutrition Evidence
FeedKind now has a substantial six-month canine ingredient study.
Cultivated-meat products need similarly transparent evidence covering the exact commercial formulas.
The strongest category comparison is not "meat versus fake meat"
The emerging protein landscape includes several distinct systems:
- Protein system
- Biological source
- Main advantage
- Main challenge
- Conventional meat
- Farmed animals
- Familiar nutrition and taste
- Land, emissions and animal welfare
- Meat by-products
- Existing animal-food chain
- Resource efficiency
- Consumer perceptions and supply dependence
- Plant protein
- Crops
- Established scale
- Amino-acid balance and palatability
- Insect protein
- Farmed insects
- Feed efficiency
- Consumer acceptance and regulation
- Microbial protein
- Fermented microorganisms
- Minimal agricultural land
- Carbon and energy inputs
- Cultivated meat
- Animal cells
- Animal protein with reduced livestock use
- Cost and scale
- Innovation Territory: Multi-Protein Pet-Food Architecture
The future is unlikely to depend on one universal replacement.
Brands may combine several systems.
The real 2025 breakthrough was two technologies reaching shelves together
February 2025 should be remembered for two separate milestones.
February 7
Meatly and The Pack sold the first limited commercial dog treat containing cultivated chicken.
February 27
Calysta and Marsapet launched the first complete dog food containing FeedKind microbial protein.
The timing made it easy to collapse both into one "lab-grown pet food" story.
They represent different futures.
Meatly asks:
Can we produce real animal cells without conventional livestock farming?
Calysta asks:
- Do we need animal cells at all to produce high-quality protein?
- FORZA10 added the missing complete-food milestone
The 2026 Coolty Meat launch filled the gap between:
- A cultivated-meat treat
- A complete diet
It demonstrated that cultivated meat could become a significant component of a nutritionally complete wet dog food rather than a novelty snack.
That is the category-defining development originally intended by the database row.
Signal: Cultivated Meat Moving From Treat to Complete Nutrition
The "first" story should become a timeline, not a single winner
A more accurate innovation timeline is:
May 2024
Dr. Clauder's announces the first dog treat using FeedKind fermented microbial protein.
July 2024
The UK approves Meatly cultivated chicken for pet-food use.
August 2024
Calysta ships commercial quantities of FeedKind Pet into Europe.
February 7, 2025
Meatly, The Pack and Pets at Home launch Chick Bites, the first commercially sold pet treat containing cultivated meat.
February 27, 2025
Marsapet launches MicroBell, the first complete dog food containing FeedKind Pet microbial protein.
May 2026
FORZA10 and BeneMeat launch Coolty Meat, described as the first complete cultivated-meat dog food commercially introduced in the EU.
Evidence Signal: Multiple Firsts Across Technology, Format and Geography
The category's biggest shift is that protein no longer has to begin on a farm
For most of pet-food history, protein came from:
- Livestock
- Fish
- Crops
The new systems add two entirely different production routes:
- Grow microorganisms
- Grow animal cells
Neither has yet displaced conventional protein at mass scale.
But both have crossed the boundary from laboratory development into commercial products.
That makes the story bigger than one dog-food launch.
The pet-food industry is beginning to treat protein as something that can be programmed and manufactured through biology rather than harvested only from agriculture.
The first lab-grown dog food did launch
It simply was not FeedKind.
The most accurate conclusions are:
Meatly's Chick Bites was the first commercial pet-food product containing cultivated meat, launched in the UK in February 2025.
Marsapet MicroBell was the first complete dog food containing Calysta's fermentation-derived FeedKind Pet protein, launched later that month.
FORZA10 Coolty Meat became the claimed first complete cultivated-meat dog food launched in the EU in May 2026.
The original finding identified a real transformation.
It assigned the wrong technology to the wrong product.
That correction makes the story more interesting, not less.
The pet-food category is not pursuing one replacement for conventional meat.
It is developing two competing biological answers to the same question:
Can we feed dogs high-quality protein without raising and slaughtering animals at today's scale?
One answer grows meat cells.
The other grows protein-producing microbes.
Both Calysta's FeedKind and cultivated meat have now reached the market.
