Legitimate premium pricing comes from clear animal protein sources, traceable supply chains and stable quality systems, all of which can be checked in public information.

Formula differences show in protein quality, fat source and functional additions, but high protein does not suit every cat, especially seniors and cats with kidney concerns.

High-budget homes should still watch the cat's response: palatability, stool quality and weight change say more than a spec sheet.

Spreading budget across the staple diet, regular checkups and a medical reserve is usually wiser than putting everything into one bag.
