I've already observed this multiple times in my ball pythons that refuse a meal, and was wondering if other people have the same experience. Where they will seem very interested in eating, but when the food is actually offered on tongs, they instead stretch their necks out past the food and out of the tub, as if the food doesn't even exist. Of course, the food is heated and scented as it usually is, and there's nothing wrong with it. If I stick the food back right into their faces repeatedly, they'll just keep moving around it and stretching their necks out past it.
Any idea what causes it? It would help to know why, since this is often how my youngest ball "refuses" food LOL. Looking super interested, but not seeing the food.
