Someone who also feeds their cats holistic food?

Right now I am feeding my two 1 year old cats, about 1/4 a cup Evo Salmon dry with about... 1 in a half tablespoons for my 7 pound kitty and about double that for my 15 pound male. I am really unsure because my wet food is Wellness and they say to feed your cat 1/2 a can per meal per Pound. Or I read it wrong? But I buy the large cans so it's confusing. So my question is, with keeping the same price range I am paying now, is wellness wet and evo dry an okay combo? And how much do YOU feed your cat?
