He is very energetic and active, hopping and climbing around, still twitching a lot but it doesn't seem to worry him. I replace the fruit after a little while, I don't leave it to sit all day. Most of the time though, if I leave him in the morning for say an hour with fresh fruit in the cage, I come back and he hasn't tried any. I'm showing him where the food is, but he much prefers that I hold it while he eats. He is very demanding for food, and will 'cheep' constantly if I'm in the room. I think perhaps he is just quite spoiled! I don't want to leave him to discover the food on his own, because obviously this would be like 'starving' him until he finds the food himself, but I'm trying to go slightly longer between formula feedings, and I take him out when offering fruit and let him have a few bites from my hand, then I'll put it in front of him so that he can eat
