I have noticed that lately my DonaTello seems to prefer me to hand feed him. I will set him in front of his food dish and he walks away. If I take a piece of romaine and offer it, he'll chomp it down like he's starving! So my question is this: is it better not to hand feed him? Am I spoiling him by doing this? I keep his food dish clean, so it's not like it smells bad. Any thoughts please?
