FOODS.EDU.VN is committed to providing accurate and reliable information. Our review process involves extensive research, including examining the brand’s recall history, manufacturing practices, ingredient quality, and customer feedback. We also conduct hands-on testing to gain firsthand experience with the products.

4. Kirkland Cat Food: Sourcing and Manufacturing
Costco, operating as a membership-only warehouse club, is the fifth-largest retailer in the world as of 2022. Headquartered in Issaquah, Washington, Costco has over 850 stores worldwide as of 2023.
Costco sources its products globally, but Kirkland Signature foods are manufactured in the United States using domestic and imported ingredients. Kirkland Signature cat food is produced by Diamond Pet Foods in five facilities across the country. Diamond Pet Foods also manufactures food for other well-known brands, including Taste of the Wild, 4health, and Chicken Soup for the Soul.
5. Has Kirkland Cat Food Ever Been Recalled?
Yes, Kirkland Signature cat food was recalled in the spring of 2012 due to potential salmonella contamination. This recall was part of a larger recall by Diamond Pet Foods, which affected numerous brands following a salmonella outbreak at its manufacturing facility in Gaston, South Carolina.
An FDA investigation revealed that Diamond Pet Foods had not taken “all reasonable precautions” to ensure product safety. The Gaston plant had previously been scrutinized for producing dog food with excessive levels of aflatoxin and lacking procedures to prevent aflatoxin contamination.
While Kirkland Signature has been involved in one recall and its manufacturer has a history of safety and quality control issues, the brand has maintained a consistent and safe record for over a decade as of this writing.
6. Exploring Kirkland’s Cat Food Options: What’s Available?
Kirkland Signature offers a limited selection of dry and wet cat food products. Dry cat foods are available in bulk bags, ranging from 18 to 25 pounds, depending on the recipe. Wet cat food is sold in 3-ounce or 3.5-ounce cans, with variety packs containing 40 or 45 trays.
The current Kirkland Signature cat food lineup includes:
- Kirkland Signature Maintenance Cat Chicken & Rice Formula Dry Food
- Kirkland Signature Nature’s Domain Salmon & Sweet Potato Recipe Dry Food
- Kirkland Signature Healthy Weight Indoor Adult Cat Formula Dry Food
- Kirkland Signature Chicken Recipe Pâté Wet Cat Food
- Kirkland Signature Turkey Recipe Pâté Wet Cat Food
- Kirkland Signature Salmon Recipe Pâté Wet Cat Food
- Kirkland Signature Chicken Recipe Chunks in Gravy Wet Cat Food
- Kirkland Signature Salmon Recipe Chunks in Gravy Wet Cat Food
All Kirkland Signature cat foods prioritize animal protein as the first ingredient. The wet cat food formulas and the Nature’s Domain dry food recipe are grain-free. The other dry foods rely heavily on rice and other carbohydrates.
7. Real-World Testing: What Did Our Test Cats Think?
Kirkland cat food may not be perfect, with recipes that are moisture-depleted, carbohydrate-heavy, and relatively low in protein, like many other dry products.
However, Kirkland stands out as an excellent option compared to other similarly priced products like Kindfull and Pretty Please. It offers superior ingredient quality without the potentially harmful additives found in other budget foods.
Kirkland’s wet foods, recently released, appear to be on par with recognizable brands like Iams and Diamond. They are a little higher in quality than store brands like Aldi’s Heart to Tail because they don’t contain meat by-products, corn, wheat, or soy ingredients.

9. In-Depth Review: Kirkland Signature Maintenance Cat Chicken & Rice Formula
This affordable kibble is a popular choice among cat owners. Formulated for all life stages, it provides well-rounded nutrition for kittens and adult cats. Chicken and chicken meal serve as the primary ingredients, offering essential amino acids for optimal health.
The formula includes whole-grain brown rice and ground white rice, which help bind the kibble and provide a satisfying crunch. Chicken fat serves as the primary fat source, offering more benefits than plant oils due to its animal-derived nature.
In addition to synthetic vitamins, minerals, and amino acids, the food contains guaranteed levels of Lactobacillus acidophilus and Bifidobacterium animalis, probiotic bacteria that support digestion and overall health.
This food is relatively low in protein and fat, with a higher carbohydrate content. It is free of animal by-products, vaguely named meats, plant by-products, and artificial colors or flavors. While it offers excellent value, it may not be the most species-appropriate choice due to its lower protein levels, higher carbohydrate content, and lower moisture levels.

10. A Closer Look: Kirkland Signature Nature’s Domain Salmon Meal & Sweet Potato Recipe
Nature’s Domain is Kirkland’s grain-free pet food line. Instead of rice and other grains, this recipe uses sweet potatoes, peas, and potatoes as starchy binders. Like all Kirkland cat foods, it includes guaranteed levels of probiotics. Chicory root serves as a source of prebiotic fiber, supporting beneficial bacteria in the gut.
This fish-based recipe lists salmon meal and ocean fish meal as its first two ingredients, followed by peas and potatoes. Canola oil is the primary fat source, which is less bioavailable than animal-sourced fats.
The food has high protein, moderate fat, and high carbohydrate content. However, with a significant amount of starch, some plant-sourced protein, and canola oil instead of animal-derived fats, it may not be the most species-appropriate choice.
Ingredients:
Salmon, Salmon Meal, Fish Meal, Sweet Potatoes, Potatoes, Peas, Pea Protein, Canola Oil (Preserved With Mixed Tocopherols), Natural Flavor, Salmon Oil (A Source of DHA), Dl-Methionine, Salt, Potassium Chloride, Choline Chloride, Taurine, Blueberries, Raspberries, Tomatoes, Dried Chicory Root, Dried Lactobacillus Plantarum Fermentation Product, Dried Bacillus Subtilis Fermentation Product, Dried Lactobacillus Acidophilus Fermentation Product, Dried Enterococcus Faecium Fermentation Product, Dried Bifidobacterium Animalis Fermentation Product, Zinc Proteinate, Vitamin E Supplement, Niacin, Manganese Proteinate, Copper Proteinate, Zinc Sulfate, Manganese Sulfate, Copper Sulfate, Thiamine Mononitrate, Vitamin a Supplement, Biotin, Potassium Iodide, Calcium Pantothenate, Riboflavin, Pyridoxine Hydrochloride, Vitamin B12 Supplement, Sodium Selenite, Vitamin D3 Supplement, Folic Acid.

11. Evaluating Kirkland Signature Healthy Weight Indoor Adult Cat Formula
Marketed for indoor cats, this Kirkland recipe aims to help cats lose weight while managing hairballs. It features chicken meal as its first ingredient, followed by ground white rice, peas, powdered cellulose, and potato protein. Chicken fat is the main fat source, along with natural flavor (likely hydrolyzed animal tissues) and a small amount of fish meal.
The formula includes dried chicory root as a source of prebiotic fiber and two species of probiotic bacteria, in addition to synthetic vitamins, minerals, and amino acids. It also contains boosted levels of L-carnitine, an amino acid that aids in converting fat into energy.
This low-calorie, high-protein, and low-fat recipe prioritizes weight management. While it may help your cat lose weight, it may not be the most nutritious option due to its high carbohydrate content.
Ingredients:
Chicken Meal, Ground White Rice, Peas, Ground Miscanthus Grass, Potato Protein, Chicken Fat (Preserved With Mixed Tocopherols), Natural Flavor, Flaxseed, Sodium Bisulfate, Fish Meal, Potassium Chloride, Choline Chloride, Dl-Methionine, Taurine, Dried Chicory Root, L-Carnitine, Dried Lactobacillus Plantarum Fermentation Product, Dried Bacillus Subtilis Fermentation Product, Dried Lactobacillus Acidophilus Fermentation Product, Dried Enterococcus Faecium Fermentation Product, Dried Bifidobacterium Animalis Fermentation Product, Zinc Proteinate, Vitamin E Supplement, Niacin, Manganese Proteinate, Copper Proteinate, Zinc Sulfate, Manganese Sulfate, Copper Sulfate, Thiamine Mononitrate, Vitamin a Supplement, Biotin, Potassium Iodide, Calcium Pantothenate, Riboflavin, Pyridoxine Hydrochloride, Vitamin B12 Supplement, Sodium Selenite,| Vitamin D Supplement, Folic Acid.

12. Reviewing Kirkland Signature Turkey Recipe Pate Wet Cat Food
This grain-free turkey recipe pate starts with fresh turkey as the first ingredient, followed by poultry broth, poultry liver, and poultry hearts. Poultry organs are nutrient-rich but lack specific source information.
Natural flavor, generally hydrolyzed protein, lacks source details. Locust bean gum, xanthan gum, and carrageenan improve texture but may cause digestive issues. Carrageenan gum has been linked to gas, diarrhea, and intestinal inflammation in some cats, although claims of it being carcinogenic are unproven.
This wet food recipe contains fewer added plant ingredients. Flaxseed meal and canola oil provide plant-based omega-3 fatty acids, but animal-based sources like salmon oil are preferable.
Overall, this wet food is high in protein and fat. The carbohydrate content appears high in the guaranteed analysis, but the ingredient list suggests a lower-carb food.
Ingredients:
Turkey, Poultry Broth, Poultry Liver, Poultry Hearts, Natural Flavor, Calcium Carbonate, Locust Bean Gum, Carrageenan, Potassium Chloride, Sodium Tripolyphosphate, Flaxseed Meal, Dried Egg Product, Salt, Taurine, Canola Oil, Magnesium Carbonate, Choline Chloride, Vitamin E Supplement, Xanthan Gum, Zinc Sulfate, Iron Sulfate, Thiamine Hydrochloride, Copper Amino Acid Chelate, Niacin Supplement, Pantothenic Acid, Pyridoxine Hydrochloride, Manganese Sulfate, Vitamin D3 Supplement, Riboflavin Supplement, Menadione Sodium Bisulfate Complex, Calcium Iodate, Folic Acid, Biotin.
Ingredients We Liked: Turkey, Dried Egg Product.
Ingredients We Didn’t Like: Carrageenan, Canola Oil.

Due to its recent release, there are limited reviews for Kirkland Signature’s wet cat food, but customers are excited about its return.
Positive Reviews:
“I have 11 cats (shh, I know). Because of the addition of the last 5 ferals l needed an economical replacement. I found it in this food, they all switched without an issue and seem to like it just fine.” — By Pamela, Kirkland Signature Maintenance Dry Cat Food on Costco.com, March 16, 2025
“I have 13 indoor/outdoor cats. They used to eat Friskies by the boatload, costing a fortune. Garbage in is garbage out, so the litter box was a full time job. At switching to Maintenance Cat there is less food consumption, less garbage coming out. The cats are in excellent health and have fur like mink. Everyone is a winner.” — By Bargainfool, Kirkland Signature Maintenance Dry Cat Food on Costco.com, March 6, 2025
Customers are generally satisfied with Kirkland Signature cat foods, appreciating the price and convenience of bulk buying. Many report improvements in their cat’s health and reduced litter box odor.

“Our Turkish Angorra who only eats dry cat food did not like it and would not eat it. Order, price and delivery process was excellent.” — By 1111, Kirkland Signature Healthy Weight Indoor Cat Food on Costco.com, March 9, 2025
“Made my cat really sick had diarrhea and threw up for 4 days got rid of it.” — By No public name, Kirkland Signature Cat Food on Costco.com, June 2025
Some negative reviews claim that Kirkland formulas made their cats sick, but these claims lack substantial evidence. Many reviewers express satisfaction but wish the carb content were lower.
