Best treat ever

My cat is dictating this review to me: These are my favorite treats out of all the things my servant gives me. I've had similar but they're not nearly as good. Inaba really started the entire puree in a squeeze tube market and they're still on top for me. These are especially great when I'm parched since they offer a lot of hydration that dry treats don't. I haven't found a flavor I don't like. Sincerely, Jinx

My new favorite

This is my first 40 oz trek tumbler of many simple modern products. The color is absolutely gorgeous. I love the variety of sizes, types, & colors of the products. I normally use the 50 oz tumbler but this will be way more convenient since it will fit in my cup holders. Although this is the first 40 oz trek i own, I'm sure there will be many more to come!
