Research overview: umami and amino-acid taste in cats

While cats cannot taste sweetness, they are highly responsive to the savory, umami-like tastes associated with amino acids and nucleotides found in meat. This overview surveys feline umami taste, mediated by receptors that detect amino acids, which is well suited to a carnivore evaluating protein-rich food. Cats show strong preferences guided by these savory tastes, helping them select nutritious animal-based foods. The survey relates umami taste to the cat's dietary needs and to the contrast with their absent sweet perception, illustrating how feline taste is tuned toward meat rather than carbohydrates. It discusses how amino acid and nucleotide combinations influence palatability. Understanding umami taste in cats complements the story of sweet blindness, showing that the feline taste system is not simply diminished but reoriented. Cats retain and emphasize the tastes that matter for a carnivore, detecting the savory signatures of protein while ignoring the sugars that signal little of value to them.
