Cats are obligate carnivores, which is a stronger statement than 'cats like meat.' Their metabolism requires nutrients found in animal tissue - including taurine, which cats cannot synthesize adequately themselves and whose deficiency causes serious heart and eye disease.
A natural feline diet is high in animal protein, moderate in fat, and low in carbohydrate. Fresh cat food brands build their pitch on matching that profile with recognizable ingredients; the honest baseline, though, is that any reputable cat food - fresh, canned, or dry - must be formulated complete and balanced to AAFCO standards, and that's the first thing to verify on any label.
