Is your cat starting to resemble a furry, four-legged carbohydrate? You’re not alone.
Over the past decade, indoor kitties have quietly become sugar-burners thanks to kibble packed with rice, potatoes, and legumes. The result: pudgy waistlines, dull coats, and a diabetes epidemic that’s breaking both hearts and wallets. Zero-carb nutrition—once a fringe idea hawked by raw-feeding forums—has now entered the mainstream, and brands like Young Again are rewriting the rulebook on what “complete and balanced” actually means for an obligate carnivore.
Before you toss the entire contents of your pantry into the trash, let’s dig into the science, the sourcing, and the sneaky label loopholes that separate truly carb-free formulas from the “grain-free” pretenders. Below, you’ll find everything you need to become the most informed shopper in the aisle—no rankings, no affiliate nudges, just the hard-earned facts every cat parent deserves.
Top 10 Young Again Cat Food
Detailed Product Reviews
1. Dr. Elsey’s cleanprotein Chicken Cat Kibble 2 lb. Bag
Overview: Dr. Elsey’s cleanprotein Chicken Cat Kibble delivers a biologically-appropriate diet in a compact 2-lb bag, targeting obligate-carnivore nutrition with 90 % animal-based protein and zero grains or gluten.
What Makes It Stand Out: The brand’s veterinary roots show—formulation reads like a feline body-condition protocol, emphasizing the highest biological-value proteins (think egg and chicken) to optimize lean mass rather than simply “fill the bowl.”
Value for Money: At $10 per pound it sits in premium territory, yet the nutrient density means smaller daily portions; most owners find one bag lasts longer than cheaper, carb-heavy alternatives, softening sticker shock.
Strengths and Weaknesses: Pros—exceptional protein purity, noticeable coat sheen within weeks, low stool odor. Cons—price, small bag size, and a crunchy texture that some picky seniors walk away from unless transitioned slowly.
Bottom Line: If your budget allows and your cat prefers poultry, this is one of the cleanest kibbles available; ideal for weight control, diabetic or allergy-prone felines.
2. Wysong Epigen 90 Starch Free Canine Feline Dry Formula Dog Cat Food (WDCFE905), Chicken, 5pounds
Overview: Wysong Epigen 90 is the first extruded kibble to achieve true starch-free status, offering a canine/feline crossover formula that pushes meat content to the edge of what dry technology allows.
What Makes It Stand Out: By eliminating starch binders entirely, Epigen 90 behaves more like a dehydrated raw—complete with probiotics, enzymes, and nutraceuticals—while still pouring from a bag.
Value for Money: $6.22 per pound undercuts most super-premium competitors, especially given the organic meat inclusion and dual-species convenience for multi-pet homes.
Strengths and Weaknesses: Pros—unmatched ingredient philosophy, rich omega-3 profile, dense nutrition reduces feeding volume. Cons—must be introduced gradually (loose stools otherwise), strong aroma, and kibble size can be large for petite cats.
Bottom Line: A science-forward choice for owners who want raw benefits without freezer space; transition patiently and you’ll be rewarded with glossy coats and small, firm stools.
3. Tiki Cat Born Carnivore High Protein Dry Cat Food, Deboned Chicken & Egg, 2.8 lbs. Bag
Overview: Tiki Cat Born Carnivore bakes rather than pressure-cooks its kibble, yielding a high-protein, low-carb recipe anchored by deboned chicken and whole egg in a 2.8-lb pantry-friendly bag.
What Makes It Stand Out: Gentle baking preserves amino-acid integrity and creates an extra-crunchy texture cats adore, while superfoods like flaxseed and salmon oil add skin-and-coat insurance.
Value for Money: Roughly $7.80 per pound positions it mid-premium—more accessible than Dr. Elsey’s yet above grocery brands; the nutrient density stretches the bag reasonably far for a single cat.
Strengths and Weaknesses: Pros—non-GMO, potato-free, highly palatable even for picky eaters; visible pumpkin aids digestion. Cons—slightly higher ash content, resealable strip could be sturdier, egg ingredient may trigger allergies in sensitive cats.
Bottom Line: A baked, bird-forward kibble that bridges artisanal ethics with everyday practicality—excellent for healthy adults needing coat gloss or weight maintenance without breaking the bank.
4. Blue Buffalo Wilderness Natural Adult Dry Cat Food, High-Protein and Grain-Free Diet, Supports Healthy Muscle Development and a Healthy Immune System, Chicken, 12-lb. Bag
Overview: Blue Buffalo Wilderness 12-lb bag brings mass-market muscle to the grain-free segment, leading with deboned chicken and fortifying with the brand’s antioxidant-packed LifeSource Bits for immune support.
What Makes It Stand Out: Scale equals savings—this is the most wallet-friendly high-protein option per pound—while still excluding by-product meals, corn, wheat, and soy, making it a safe supermarket upgrade.
Value for Money: At $3.50 per pound you’re paying mid-tier prices for near-premium macros; the bulk bag slashes cost further for multi-cat households.
Strengths and Weaknesses: Pros—wide retail availability, consistent quality control, palatability across life stages. Cons—contains pea protein to inflate numbers, some cats pick out the darker LifeSource Bits, and carbohydrate level is modestly higher than ultra-premium rivals.
Bottom Line: A reliable workhorse kibble that democratizes high-protein feeding; perfect for budget-conscious households or as a base mixed with toppers and wet food.
5. Dr. Elsey’s cleanprotein Protein Bites Chicken 6 oz.
Overview: Dr. Elsey’s cleanprotein Protein Bites compress the brand’s veterinary nutrition into a 6-oz pouch of 59 % protein treats—grain-free, low-carb morsels suitable from kittenhood through senior years.
What Makes It Stand Out: Unlike typical “junk” treats, these deliver complete and balanced nutrition, effectively doubling as a high-value training reward or meal topper without sabotaging weight plans.
Value for Money: $1.32 per ounce is pricey versus Temptations, yet each bite is so protein-concentrated that one or two satisfies; the bag lasts longer than cheaper carb-laden alternatives.
Strengths and Weaknesses: Pros—made from the same high-biological-value chicken as the kibble, no glycerin or sugar, resealable pouch keeps crunch. Cons—small portion size invites sticker shock, strong smell may offend humans, and cylindrical shape can roll under furniture if dropped.
Bottom Line: The guilt-free treat for nutrition purists—use sparingly for pill delivery or clicker training and you’ll justify the cost while keeping your cat lean and engaged.
6. ZIWI Peak Steam & Dried Cat Food – Cage-Free Chicken w/Whole Mackerel – High Protein, Skin & Coat Health, Low Carb, for All Life Stages (28.8oz)
Overview: ZIWI Peak Steam & Dried Cat Food combines cage-free chicken and whole mackerel in an innovative two-step process that steams then air-dries ingredients, creating a nutrient-dense meal that’s 90 % meat, organs, and bone. Designed for all life stages, this 28.8 oz bag promises the convenience of shelf-stable kibble with the nutritional punch of fresh food.
What Makes It Stand Out: The gentle steam-then-dry technique locks in omega-3s from wild-caught New Zealand mackerel while preserving natural enzymes usually lost in high-heat extrusion. The result is a crunchy, raw-alternative kibble that needs no freezer space and can double as a high-value topper.
Value for Money: At $19.43 per pound this is luxury pricing, but you’re paying for ethically sourced, hormone-free proteins and a process that retains more bio-available nutrients than typical dry foods. Fed as a topper, one bag stretches surprisingly far, lowering the daily cost for multi-cat households.
Strengths and Weaknesses: Strengths include unmatched ingredient integrity, palatability even for picky eaters, and visible coat improvement within weeks. Weaknesses are the premium price tag, strong fish aroma that some owners dislike, and calorie density that requires careful portioning to prevent weight gain.
Bottom Line: If budget allows, ZIWI Peak is one of the closest-to-raw dry options available. Serve it full-time for maximal benefits or sprinkle half-portions over less-expensive kibble to upgrade any bowl.
7. ORIJEN Grain Free High Protein Premium Dry Cat Food Original Recipe 4lb Bag
Overview: ORIJEN Original Cat Food delivers a biologically appropriate diet in a 4 lb bag packed with 90 % animal ingredients. The first five components—fresh or raw free-run chicken and turkey, whole mackerel, turkey giblets, and flounder—mimic the prey model, while freeze-dried coating adds a burst of raw flavor indoor cats crave.
What Makes It Stand Out: Unlike grain-free competitors that rely on legumes, ORIJEN keeps carbohydrate content ultra-low and includes WholePrey ratios of meat, organs, and cartilage, naturally supplying taurine, vitamins, and minerals without long synthetic lists.
Value for Money: At $8.00 per pound the food sits in the upper-mid tier; yet dense calorie count means smaller daily servings, bringing the monthly cost close to cheaper brands that require larger scoops.
Strengths and Weaknesses: Strengths include shiny-coat results, small firm stools, and high palatability even for senior cats. Reported weaknesses are occasional batch variations in kibble color, strong smell during transition weeks, and price jumps when bought in smaller bags.
Bottom Line: For owners seeking a high-protein, low-carb kibble that respects feline anatomy, ORIJEN Original is a benchmark. Transition gradually and store the freeze-dried-coated kibble in a cool, sealed container to preserve its raw aroma.
8. Nulo Freestyle High Protein Cat & Kitten Food, Chicken & Cod Recipe – Natural Grain-Free Dry Cat Food with Omega Fatty Acids & Probiotics, 4 lb Bag
Overview: Nulo Freestyle Chicken & Cod Recipe targets both kittens and adults with deboned chicken as the first ingredient, followed by turkey meal and cod. The 4 lb bag combines 83 % animal-based protein with BC30 probiotics and balanced omega fatty acids to support digestion, immunity, and a glossy coat.
What Makes It Stand Out: Disc-shaped kibble is smaller and thinner than most premium brands, making it easier for kittens, seniors, or flat-faced breeds to chew. Added taurine and vitamin-E-rich sunflower oil round out a formula free of grains, white potatoes, and tapioca.
Value for Money: At $5.75 per pound Nulo undercuts many super-premium competitors while still offering probiotics and high fresh-meat inclusion, delivering solid middle-tier value.
Strengths and Weaknesses: Strengths include excellent stool quality, reduced hairballs, and a resealable bag that actually stays closed. Some cats find the cod scent too mild compared with fish-heavy diets, and calorie count is moderate, requiring measured portions for less-active indoor cats.
Bottom Line: Nulo Freestyle is a smart pick for multi-age households that want high animal protein, digestive support, and budget sanity. Rotate flavors to keep interested cats engaged without stomach upset.
9. Open Farm, Grain Free Dry Cat Food, High-Protein Kibble for a Complete & Balanced Diet, Non-GMO Fruits & Vegetables, Prebiotic Fibers to Support Digestion, Wild-Caught Salmon Recipe, 4lb Bag
Overview: Open Farm Wild-Caught Salmon Recipe centers on sustainably sourced salmon paired with non-GMO pumpkin and dandelion greens. The 4 lb grain-free kibble is designed for complete nutrition while emphasizing traceable, third-party-certified ingredients and digestive health.
What Makes It Stand Out: Open Farm publishes every ingredient’s origin online, offering rare transparency. Prebiotic fibers from pumpkin plus salmon’s natural omega-3s create a gut-friendly, skin-soothing combination that many allergy-prone cats tolerate well.
Value for Money: At $7.50 per pound you pay slightly more than mainstream grain-free brands, but the ethical sourcing audit and absence of rendered meals justify the uptick for eco-conscious shoppers.
Strengths and Weaknesses: Strengths include smaller, airy kibble that’s easy to chew, minimal stool odor, and a resealable matte bag that blocks light. Weaknesses are occasional availability issues, salmon scent that lingers in small apartments, and protein level (36 %) that’s lower than some competitors.
Bottom Line: If ingredient traceability and sustainable fishing matter to you, Open Farm delivers trustworthy nutrition without breaking the bank. Ideal for cats with grain sensitivities or owners transitioning away from poultry-heavy diets.
10. Tiki Cat Born Carnivore High Protein, Indoor Health, Chicken and Turkey Meal Recipe, Grain-Free Baked Kibble to Maximize Nutrients, Dry Cat Food, 3 lb. Bag
Overview: Tiki Cat Born Carnivore Chicken & Turkey Meal Recipe offers indoor cats 36 % guaranteed protein in a 3 lb bag of grain-free baked kibble. Chicken leads the ingredient list, followed by turkey meal and carefully selected plant fibers to minimize hairballs and control calories.
What Makes It Stand Out: The baking process uses lower temperatures than extrusion, helping retain amino acids while creating a crunchy texture that reduces tartar. Added omega-3 and -6 fatty acids target skin and coat issues common in lower-activity indoor cats.
Value for Money: At $5.40 per pound this is the most affordable option among reviewed premiums, making high-protein feeding accessible for singles or multi-cat homes on tight budgets.
Strengths and Weaknesses: Strengths include high palatability, small kibble size suited to adults and kittens, and noticeably less yard-style smell in the litter box. Drawbacks are the use of “meal” rather than fresh meat as the second ingredient, limited flavor variety, and a bag that lacks a zip seal—plan to transfer to an airtight container.
Bottom Line: Tiki Cat Born Carnivore is a wallet-friendly gateway into quality nutrition for indoor cats. Pair it with wet food for moisture or feed solo for convenient, baked high-protein crunch.
Why Zero-Carb Matters for Obligate Carnivores
Cats lack salivary amylase, produce minimal pancreatic amylase, and divert very little glucose to glycogen storage. Translation: every gram of starch they swallow is either burned immediately (spiking blood sugar) or converted to body fat. Over time, that metabolic mismatch shows up as obesity, periodontal disease, and the dreaded “kitty Type 2.” A zero-carb approach mimics the macronutrient profile of a mouse—roughly 55 % protein, 45 % fat, 0 % NFC (nitrogen-free extract, the lab term for carbs).
The Evolutionary Diet of Wildcats vs. Modern Domestic Cats
African wildcats—your tabby’s closest kin—consume less than 2 % carbohydrates, and even that comes from the undigested stomach contents of prey. Compare that to many “premium” diets hovering at 25–40 % carbs, and it’s easy to see why domestic cats now suffer diseases their desert cousins never face. Evolution hasn’t had time to re-engineer the feline liver; we owe them a diet that respects their ancestral blueprint.
Debunking the “Grain-Free” Myth
Grain-free merely means no corn, wheat, or soy. Manufacturers simply swap in peas, tapioca, or lentils—carb sources that spike the glycemic index even faster than cracked corn. The only number that matters is “NFC” or “starch + sugar” on the guaranteed analysis. If it’s above 5 %, you’re still feeding a high-carb diet in a grain-free tuxedo.
How Young Again Redefined Species-Appropriate Kibble
Young Again pioneered a process that gelatinizes animal protein without traditional starch binders. Instead of wheat gluten or potato starch, they use a proprietary matrix of collagen and pork plasma—ingredients that double as functional binders and palatability boosters. The resulting kibble contains <1 % digestible carbohydrate, a figure verified by independent labs using AOAC 2002.02 enzymatic assay.
Key Nutrient Targets in a True Zero-Carb Formula
Protein ≥ 50 % (dry-matter), fat 20–25 %, combined omega-3 (EPA/DHA) ≥ 0.35 %, taurine 0.3 %, phosphorus 0.8–1.0 % with a Ca:P ratio between 1.1:1 and 1.3:1. Fiber should stay under 3 %—any higher and you’re diluting nutrient density and tempting litter-box rebellion.
Ingredient Red Flags: Hidden Carbs & Fillers
Watch for “pea protein,” “sweet-potato flakes,” “beet pulp,” and the ultimate wolf in sheep’s clothing—“dried fermentation products,” which can contain residual maltodextrin. Even “animal digest” sometimes arrives sprayed with dextrose for dust control. If the label lists anything that sounds like a Thanksgiving side dish, leave it on the shelf.
Reading the Guaranteed Analysis Like a Clinical Nutritionist
Subtract protein, fat, fiber, moisture, and ash from 100 %. What’s left is NFC—non-structural carbs. Aim for <5 %, ideally <2 %. Remember, ash values are rarely printed on the bag; email the company and ask for the typical analysis. Reputable zero-carb brands will share it within 24 hours.
Transitioning Your Cat Without GI Revolt
Cats are creatures of routine; their gut microbiome is no different. Mix 25 % new food with 75 % old for three days, then 50/50 for three, then 75/25. If you see soft stools, pause for 48 hours and add a feline-specific probiotic containing Enterococcus faecium SF68. Most cats fully transition within 10 days, though keto-adaptation (the switch to fat-burning) can take 3–4 weeks.
Managing the Keto-Adaptation Phase
Expect a temporary dip in energy and possibly a “ketone breath” odor. Provide ample water—ketosis increases renal solute load—and monitor urine with inexpensive keto-dipsticks. If ketones register above 5 mmol/L, offer a teaspoon of plain meat baby food to gently nudge the pH back toward neutral.
Weight-Loss vs. Weight-Maintenance Protocols
For safe weight loss, target 60 kcal per kg ideal body weight, divided into 4–5 micro-meals to blunt cortisol spikes. Once the waistline returns, bump to 70–75 kcal per kg. Use an infant scale to track; cats should shed no more than 1 % of body mass per week. Rapid fat loss risks hepatic lipidosis—the ultimate irony of a diet gone wrong.
Urinary pH & Mineral Balance on Zero-Carb Diets
High-protein, low-residue foods can acidify urine, predisposing cats to calcium oxalate crystals. Offset this by ensuring 70 % of the diet’s phosphorus comes from bone rather than synthetic dicalcium phosphate, and by maintaining moisture ≥ 65 % if you feed any freeze-dried toppers. Routine urinalysis every six months is cheap insurance.
Dental Health: Do Low-Carb Kibbles Really Clean Teeth?
Traditional “dental” kibbles expand on contact with saliva, acting like mini sponges that scrape plaque. Zero-carb extruded pieces are denser and shatter cleanly, producing a mild abrasive action. Still, they’re no substitute for enzymatic gel or raw meaty bones. Think of them as floss, not a toothbrush.
Cost Analysis: Is Zero-Carb More Expensive Long-Term?
Sticker shock is real—zero-carb bags average $0.45–$0.60 per ounce versus $0.18 for grocery-aisle kibble. But factor in 25 % lower daily caloric needs (no carb energy waste), 40 % fewer vet visits for diabetes management, and the price per healthy year of life drops below the cheap stuff. spreadsheet it out; the math surprises most skeptics.
Sustainability & Sourcing: What to Ask the Manufacturer
Inquire about country of origin for every animal protein. Ask whether the fish meal is certified by the Marine Stewardship Council and if chicken fat is preserved with mixed tocopherols rather than ethoxyquin. Finally, request a letter of assurance that plasma proteins are collected from USDA-inspected facilities—this single clause screens out most render-by-product loopholes.
Common Mistakes Owners Make When Buying “Zero-Carb”
- Trusting the marketing blurb instead of the NFC math.
- Ignoring ash content and ending up with hyperphosphatemia in senior cats.
- Over-feeding because kibble “looks” tiny—calories, not cup size, matter.
- Forgetting to increase water stations; concentrated diets amplify dehydration risk.
- Skipping baseline bloodwork and thereby missing pre-existing kidney issues that high protein could unmask.
Frequently Asked Questions
1. Is zero-carb safe for kittens or only adult cats?
Yes, provided the formula meets AAFCO growth profiles and delivers 1.2–1.4 % calcium on a dry-matter basis.
2. Will my cat develop constipation without fiber?
<3 % fiber is still present as fur and connective tissue in animal ingredients; most cats do fine, but add a moisture-rich topper if stools become hard.
3. Can I mix zero-carb kibble with raw food?
Absolutely—just account for calories so you don’t double-feed, and serve the raw at a separate meal to keep gastric pH optimized for each.
4. How do I know if my cat is in ketosis?
Urine dipsticks or a pet breath-ketone meter; values of 0.5–3 mmol/L indicate healthy nutritional ketosis.
5. Are there any breeds that should avoid zero-carb?
Maine Coons and Ragdolls with known predisposition to calcium oxalate stones need extra urinary monitoring, but the diet itself is not contraindicated.
6. Does zero-carb prevent hairballs?
Hairball formation is more about grooming frequency and hydration than carbs; expect similar frequency, smaller volume.
7. Is fish-based zero-carb better than poultry-based?
Rotate both to balance omega-3:6 ratios unless the fish formula already includes 0.35 % added DHA.
8. How long before I see weight loss?
Visible waistline changes appear around week 3, with 6–8 % body-mass reduction by week 8 if calories are controlled.
9. Can diabetic cats come off insulin on zero-carb?
Never adjust insulin without veterinary supervision; many cats achieve remission, but hypoglycemia can be fatal if insulin isn’t tapered.
10. What’s the shelf life of an open zero-carb bag?
Six weeks maximum if stored below 80 °F and sealed with the original foil liner; for longer, vacuum-portion and freeze.
