    I have 8 cats. Transitioned to Kirkland dry cat food due to price. All 8 cats have yellow diarrhea and lethargic. One also developed urinary crystals. This is after 5 days of feeding. This food is toxic! Do not feed to your cats!

      My Cat loves the Nature's Domain dry cat food, and the Kirkland Signature Pate wet food. Silky coat. Firm poops. And I love the Costco price. Diamond Pet Foods makes the Costco brands and the Taste of the Wild and Diamond Naturals. All great brands.

      I had been using Kirkland Maintenance Cat Chicken and Rice formula for years for my 2 cats. I bought a new bag and my 2 cats both suddenly started having diarrhea in the middle of the night, and going multiple times a day. One of my cats got mucus in his stool, and the other cat got blood. Both of them had runny, smelly, diarrhea. This went on for about 3 weeks. I did not realize it was from the kibble, because it was the same food (so I thought) that I'd always used, and I forgot that I'd started using the new bag. At the time I thought something else had caused it, so I was modifying the wet part of their diet but kept giving them the kibble.

      Then I saw an episode of a show where a batch of pet food was contaminated and I suddenly remembered I had just started a new bag of Maintenance Cat. I discontinued the food and now 2 days later they are almost back to normal. I guess I am lucky that this was only half of their diet or they could have been in trouble. Upon researching, I've been reading more and more stories like this, but there has been no recall issued. Sadly I cannot trust this brand and I'm moving on to a different brand even though I love the ingredients in Maintenance Cat. You can see the lot number in my photo. This bag was bought at Costco Temecula in Sept 2025.

      I have been feeding my cats the Kirkland Chicken and Rice formula. Lately I noticed that they were only eating half the kibble and leaving the remainder in their bowl. No matter how hungry they were, they would not touch those little halves. I came home on Monday and couldn't find one cat. Found him very sick and in pain and could hardly move. I rushed him to the vet, and there was nothing they could do. $800 vet bill and I didn't get to bring him home. There is something seriously wrong with that cat food!

      My cat use to eat the chicken and salmon flavors about a year ago. Kirkland then changed the formula and now the consistency is mushy, horrible and repulsive. Not only does my cat not eat it now but the stray cats around my house refuse it also. Racoons are the only ones that will eat it. GO BACK TO THE OLD FORMULA!!!

      If I could give this food a 0 I would. We started giving our cat the pate wet food variety pack because she was a picky eater and she liked it. Fast forward 9 months since starting it and her phosphorus levels skyrocketed, putting her in stage 3 kidney disease. We just put her down today and I'm 100% convinced this food is what did it. Read other reviews, this isn't a coincidence!

      I recently started giving my cats Kirkland dry food, about a 1/4 cup each, 2-3 times a day. They also have fully switched to Kirkland pate. Unfortunately, they have both come down with stinky diarrhea with blood, and listlessness. I am returning the five boxes of wet food to Costco, and throwing away that huge bag of dry food. It's been an expensive loss, also with the Vet bills that happened as a result. I am worried about my cats.

      I had two cats. At first they ate the Costco wet food but then months later they started throwing up and ate less but still threw up. The more time they ate this food the more constant and more frequent they threw up. My middle aged cat developed horrible diarrhea at which point I changed to a well known national brand. But this was too late and he died. The younger cat became very thin and remained hidden most of the time. She eventually recovered some of her energy and has gained some of her weight back. She refuses to eat the Costco wet food to this day. Please carefully monitor your cat's health and weight if you use this product.

      My cat tolerated Kirkland Premium Pate' for several months before straight up refused to eat it anymore. It caused her continuous constipation so I added broth or pumpkin puree often. My mistake for keeping her on this brand. She was giving me clear indications she wasn't happy and I didn't catch on fast enough. My cat has never been a picky eater. Her lack of enthusiasm, body functions, and final refusal to eat told me everything.
