So, I just fed my ball python an adult mouse. This is what he always eats once a week, never with any complications. Well i just fed him now and he has a protruding lump coming out of his stomach where the mouse is. It's about the size of a peanut or a little larger and hard. It's protruding really far out of his stomach and I'm really scared and worried. Does anyone know what this could be? Could it be the mouse's head? It's sticking really far out of his stomach though :(
