I would only put out enough for the day. I give Bijou and Mika between 1/3 and 1/2 cup of Orijen per day. They get wet food morniing and night. Mika actually prefers dry and Bijou wet but they both eat both wet and dry. Bijou is usually asking for his wet food when we get home from work whereas Mika will go first to the dry and then the wet.
By the time I get home from work in the evening, both dry and wet food bowls are empty.
