Wellness vs Blue Buffalo Cat Food (2026): Which Premium Brand Wins?

US retailer copies of Wellness CORE Original Deboned Turkey, Turkey Meal and Chicken Meal list the same opening: deboned turkey, deboned chicken, turkey meal, chicken meal, then peas. Salmon oil is named further down, with flaxseed, cranberries, and chicory root. A current Chewy copy puts chicken fat and herring meal just after peas, then dried beet pulp and salmon oil. An older US copy puts herring meal after peas and dried ground potatoes before the salmon oil. The first four names match. The middle of the list does not. A European CORE Original page is a third recipe, with potato protein and a 44 percent protein line. Do not treat that bag as this one.

The guaranteed analysis on those US copies agrees on the big minimums: at least 45 percent crude protein and at least 18 percent crude fat. Moisture is at most 10 percent. Taurine is at least 0.20 percent. Fiber is where the copies split. Some pages print 3 percent maximum crude fiber. The current Chewy table prints 4 percent. Calories split the same way. Older pages print 3,977 kcal per kilogram, or 497 kcal per cup. Chewy prints 3,783 kcal per kilogram, or 473 kcal per cup. Use the cup line on the bag you opened.

A retailer nutrition statement for this recipe says it is formulated to meet the AAFCO Cat Food Nutrient Profiles for maintenance. A shop filter can still say all life stages. The sentence on the bag is the one that matters. Maintenance is adult maintenance. It is not a kitten growth statement. Some guaranteed analyses also print 90,000,000 CFU per pound of lactic acid microorganisms. A short table may leave that line off. That line is a label claim about added microbes. It is not a stool result.

Current retailer copies of Blue Buffalo Wilderness Adult Chicken agree on the opening: deboned chicken, chicken meal, pea protein, tapioca starch, peas, then menhaden fish meal. Chicken fat is preserved with mixed tocopherols. Flaxseed is named as an omega-6 source. The fish meal is the named omega-3 source. Salmon oil is not on this list. LifeSource Bits is the brand name for the vitamin and mineral pieces. That is a marketing line, not a nutrient we measured.

The guaranteed analysis on those copies is 40 percent minimum crude protein, 18 percent minimum crude fat, 4 percent maximum crude fiber, and 9 percent maximum moisture. Magnesium is 0.14 percent maximum. Taurine is 0.15 percent minimum. Omega-3 fatty acids are 0.5 percent minimum and omega-6 fatty acids are 3.5 percent minimum. The calorie line is 3,832 kcal per kilogram, 443 kcal per cup. An older Blue page for a chicken recipe under this name used turkey meal and potato starch instead of pea protein, with 3,682 kcal per kilogram. The bag in the cupboard wins over either page.

Pea protein is a plant concentrate. It counts toward the 40 percent. A five-point gap under CORE’s 45 percent minimum is not a five-point gap in meat. Both numbers are as-fed minimums on dry food. Neither is a dry-matter assay of the cup you pour.

This is the with-grain Wellness bag on this page, not a second CORE. Retailer copies list deboned chicken, chicken meal, rice, barley, and oats, then chicken fat and ground flaxseed. Tomato pomace, cranberries, and chicory root extract follow. The copies read here do not name salmon oil. Flaxseed is the plant omega source on the list.

The guaranteed analysis is 38 percent minimum crude protein, 18 percent minimum crude fat, 3 percent maximum crude fiber, and 10 percent maximum moisture. Taurine is 0.20 percent minimum. Omega-6 fatty acids are 3.60 percent minimum and omega-3 fatty acids are 0.60 percent minimum. One retailer copy prints 3,952 kcal per kilogram, or 458 kcal per cup. The nutrition statement says the recipe is formulated for AAFCO maintenance.

A grain-free Complete Health chicken, a senior Complete Health, and a CORE digestive grains recipe are other bags. They print different protein and ingredient lines. If the sack says wholesome grains and the first five match chicken, chicken meal, rice, barley, and oats, you are on this one.

Wilderness Indoor Chicken is not the adult Wilderness bag with a new sticker. Retailer copies open with deboned chicken, chicken meal, pea protein, peas, and tapioca starch. Powdered cellulose shows up after flaxseed. That cellulose line is the indoor fiber. Menhaden fish meal and flaxseed are still the named omega sources. Salmon oil is not on this list.

The guaranteed analysis drops from the adult chicken bag: 38 percent minimum protein, 16 percent minimum fat, 6 percent maximum fiber, 9 percent maximum moisture. Calories are 3,671 kcal per kilogram, 410 kcal per cup. Taurine is 0.15 percent minimum and magnesium is 0.14 percent maximum. A retailer page says the food is formulated for AAFCO maintenance. The adult chicken bag was 40 percent protein, 18 percent fat, 4 percent fiber, and 443 kcal per cup. Those are the indoor changes. They are not a prescription calorie plan. Portion the cup to the cat’s body condition.

Public copies of this CORE chicken, turkey, and chicken liver pate do not share one ingredient list. One deck starts chicken, turkey, chicken broth, chicken liver, chicken hearts, then dried ground potatoes and fish oil. Another starts chicken, turkey, chicken broth, chicken liver, chicken meal, turkey liver, then salmon oil. Both keep named poultry at the front. Both use cassia gum, xanthan gum, and guar gum. Neither puts pea protein in the first five. Carrageenan is not on these copies. An indoor CORE pate is a different can, and that one does list pea protein. Check the can name.

The analysis is steadier on protein and water than on fat. Crude protein is at least 12 percent. Moisture is at most 78 percent. Taurine is at least 0.1 percent. Fat is printed as 7 percent, 7.5 percent, or 8 percent minimum, depending on the page. One copy prints 1,194 kcal per kilogram, or 101 kcal per 5.5 ounce can. Another page of the same recipe name says the food is formulated for all life stages. Other pages do not print that sentence in the table. The can’s statement is the one to follow. Twelve percent protein beside a dry food’s 45 percent is not a quality gap. Most of the can is water. That water is why the pate is here.

Tastefuls pate is the Blue wet food linked on this page. It is not Wilderness in a can. A Petco 5.5 ounce variety pack lists three recipes: chicken, turkey and chicken, and ocean fish and tuna. The chicken recipe opens with chicken, chicken broth, chicken liver, natural flavor, and brown rice, then guar gum, sweet potatoes, powdered cellulose, and carrageenan. The turkey recipe opens with turkey. The fish recipe opens with whitefish on a grocery-pack copy and is a separate entree. Brown rice means the pack is not grain-free.

On that Petco pack the chicken can is 10 percent minimum protein, 6 percent minimum fat, 2 percent maximum fiber, and 78 percent maximum moisture. A Canadian variety page prints 9 percent protein and 82 percent moisture for the chicken entree, and a calorie line that does not match the Petco can. Read the tray you bought. A variety-pack page says Tastefuls adult food is formulated for AAFCO maintenance. A Chewy transition line for Tastefuls chicken pate says to mix the new food in over 14 days. Other bags on this page print their own charts. Use the chart on the food you are opening, and call a veterinarian if the cat stops eating or the stool changes.
