Our new little guy is incredible, but we're having some issues with feedings. We're trying to feed him 3 times a day, giving him like 20 minutes each time to eat (trying to avoid the freefeeding), but he only eats a part of his food. We're giving him ½ a cup at a time, but he only eats like ¼ of that. I know when we got him he was weened onto food and they (meaning the breeders) didn't mention having any problems with feeding him. Any suggestions?
