Pygmy puffs will eat anything that is not too much bigger than they are. They will even eat live insects. Keep your potions ingredients and wand out of sight. You should experiment, find out what your puff likes to eat. Don´t give your puff too much food or else it will get over weight. Pygmy puffs can´t eat chocolate, it´s poisonous for them, and can either kill them or make them very ill.
