Baby BP got an RI?

Today I did what I usually do when I get my 6 month old BP out. Check for any wheezing/ coughing and others symptoms or a RI. But today I checked his mouth and saw a few bubbles when he moved his teeth, to me this is very worrying because on top of this he is due a shed for about two weeks now but still no sign of shedding. The temp. And humidity are fine and there is no Mucus around the cage or anywhere.

A few bubbles in the throat are perfectly normal - especially if you are restricting his movement to open his mouth.

I don't worry about RI's unless there are multiple signs. And when shedding it is not unusal to hear them breathe or whistle more as the nostrils get narrowed by the shedding process. :)
