What % should protein be?

Is 50% protein too much??? I was looking at the new Innova (EVO) food which is supposed to be like feeding raw, but the protein level does seem to be high. What do you all think?

High protein is fine for healthy cats. Calories are supplied by carbs, protein and fat. This is a low carb food...in order to reduce the carbs, the protein levels must be increased. Also, keep in mind that comparing the minimum percentages in the guaranteed analysis is not accurate because of the calorie differences amoung various brands.

According to the AAFCO nutrient profiles, the minimum amount of protein should be no less than 26% for adult maintenance and no less than 30% for growth and reproduction assuming an energy density of 4 kcal/g ME. Foods with greater than 4.5 kcal/g ME will required higher levels of protein.

Nern gave you a great answer, I'll just say I think it sounds like an exciting option, and may give it a go myself with those of my kitters not on a special diet.

Thanks for clearing that up, appreciate it.

On this same note Purina Pro Plan now has a few flavors with 40% protien.... ingrediants are bad but still not something I would give..
