I would like to know how often I can/should feed my hc the "people food"? So far, I tried feeding him a piece of zuccini, a baby carrot, a blueberry, romaine lettuce... I know they take small small bites but I don't think he touched anything. I put the food in the evening and take it out in the morning. Tonight I want to give him scallop but not until I know how often he should have food other than hc pellets... Thanks.
