after i fed my tegu a couple mice yesterday i saw his eyes watering up, i figured he just got some of his substrate in them and it was getting cleaned out. but then he looked in a different direction and it looked like a few bubbles popped up in the front of his eye for a couple seconds, what could this be? he also bit me a couple hours later when i took him out, and he's never even tried to bite me in the year i've had him.
thanks
