I'm not sure what it is, but there is this squishy area (about the size of an egg cut in thirds) on the lower neck on the belly of my snake. It's about 5" down from the head. His neck looks skinny and then kinda bulges out where this blister area starts. I felt it and it feels like its full of water and air bubbles. Could a mouse bite cause this? Should I do anything about it?
