For pellets (as your base diet), I recommend Harrison's Adult Lifetime Super Fine, Top's mini pellets, or Roudybush Nibbles. Also, remember to feed fresh vegetables/chop, place a bowl of chop in the cage for the day. Seeds make good treats for lovies. Also, herbs and grains can make nice additions to the diet, as well as occasional fruit (though fruit is not needed). Do NOT feed avocado, tomato, rhubarb, mushrooms, or any salty, sugary, or fatty foods.
