Costco sells a ton of cat food options, which was a nice surprise. I usually get Kirkland cat food dry and some wet food like salmon pate. Sheba cat food from Costco is also great for a treat. My cats are picky, but this combination keeps them happy. The price is excellent, especially compared to Chewy or Petco. I even saw some people talk about Costco Blue Buffalo cat food, but I personally stick to Kirkland and Pure Cravings. Overall, Costco is convenient, affordable, and my cats enjoy every meal.
