Placeholder. A Japanese cat food brand solved the universal, mundane annoyance of half-used cans and lingering fridge odor not through a new ingredient or health claim, but through a deceptively simple format change — individually sealed single-serving cups using real Japanese dashi broth instead of generic gravy.
What we've found so far: INABA Dashi Delights uses six sealed 2.5oz single-serving cups per pack with authentic bonito dashi broth, chicken/tuna/scallop pieces, eliminating the refrigerator odor and wasted half-can portions common to standard canned wet cat food.
