the science of flavor

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

taste

cats prefer umami & kokomoi flavors

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

cat 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

Why is hydration so important for cats?

Hydration is the backbone of feline health. It supports kidney function, urinary tracthealth, and digestion. Chronic dehydration is one of the most common feline health issues, asmany cats only drink about half of what they actually need (Kosmal et al., 2025).

Does feeding my cat only dry food put them at higher risk of dehydration?

Yes. Dry food is only ~10% moisture vs. ~80% for wet food. Instead of drinking morewater to make up for the dry food, cats compensate by holding onto water by concentrating theirurine more. Cats on wet diets take in about 51% more total water than cats on dry diets (VanDiggelen et al., 2026).

How do cat years Hydration Boosters actually work?

cat years uses a proprietary feline hydration blend of amino acids, electrolytes, andosmolytes that help boost water absorption, optimize water balance, and keep cells hydrated inhealthy adult cats. The formula was developed by PhD experts in hydration and feline nutrition(Kosmal et al., 2026).

Is cat years clinically proven?

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

How do I feed cat years to my cat?
