From my experience, however limited, it is to do with teeth health. I have gotten in many with poor dental and one had to have many teeth removed. He will crush his food against the bowl to eat. I can only guess because of his lack of teeth. He does not like soft/liquid foods that well. So my wager is teeth issue. Either they are causing a discomfort or ?
