Today I went to pair up Jack and Anita because my dad forgot to before he left town for Nebraska. I picked Jack up out of his cage and noticed a bubble on each side of his mouth. As he started moving around they popped but I felt the sides of his mouth and they were all wet. His breathing sounded fine and I checked inside his mouth but everything looked fine. Is this something I should worry about? I kept him in his own cage and away from the other snakes. Could this be something serious or did he just take a big drink of water?
