the science of flavor

we crafted a recipe that delivers on what cats care about most
taste

cats prefer umami & kokumi flavors

  • the same amino acids that boost hydration amplify those flavors even further
flavor

cats noses are 14x stronger than ours

  • cooking with amino acids triggers the maillard reaction (the same chemistry behind a seared steak's crust), amplifying an aroma cats can't resist
texture

cats have ⅓ the taste buds we do

  • so aroma and texture drive their preferences more than taste, and our smooth, creamy texture carries flavor across their tongue with every lick

cat years is the best of both worlds: the delicious lickable treat your cat loves and clinically proven to boost hydration. Our proprietary blend of amino acids, electrolytes, and osmolytes helps boost water absorption, optimize water balance, and keep cells hydrated in healthy adult cats (Kosmal et al., 2026). Formulated by PhD experts in hydration and feline nutrition. Vet recommended for daily use.

What ingredients are in cat years?

cat years is made with fresh chicken breast, wild-caught tuna, and a proprietary hydration blend of amino acids, electrolytes, and osmolytes. It is non-GMO and free from artificial flavors, artificial colors, preservatives, by-products, and added phosphorus. cat years is formulated only with ingredients commonly recognized as safe for cats.

Is cat years clinically proven?

Yes. In a University Department of Animal Bioscience led study, one cat years Hydration Booster per day drove a statistically significant increase in hydration. This is based on two key biomarkers – increase in total water intake and decrease in urine specific gravity (i.e., urine concentration) (Kosmal et al., 2026).
