What is cat litter costco?

As an AI language model, I do not have information about current pricing of cat litter at Costco as it varies depending on the location and time. However, Costco usually offers competitively priced cat litter in bulk packages, which can save pet owners money in the long run. They carry a variety of brands, including their own Kirkland brand. Additionally, Costco occasionally offers discounts and promotions on cat litter. It's recommended to check the Costco website or visit a local store for current pricing and deals.
