Carpet mouth? Saliva or R.I

[Kimberlyann]

So a couple of people know the story of this snake. So to top everything that has happened i think he might be getting a R.I
We had him out for some lawn time this arvo and he opened his mouth so i thought i might give him a bit of a check over, grabing the first thing i could i opened up his mouth and saw what looked like saliva but im not sure if snakes have a bit of saliva in their mouths like we do? I tried to get a friend to take some shots to show but this is all i got..... ill add a couple more of him too
We have him set at 30degree's so i have no idea how he has gotten it :?

Just like us sometimes they have a bit of extra saliva
I wouldnt be sweating about this one too much
With a nice docile one like that
hold his chest up near your ear
If there is RI you will hear it quite clearly in a snake that size

The first head shot of him on the grass, is it just the light or does his eye seem faintly blue? He might be gonna come into shed.

Couldn't hear anything, i've had a carpet before with a R.I, medicine never worked on her she had a blocked nose and was drolling she had that much mucas (sp?) coming out her mouth so i know what it sound's like. He hiss's a bit but no wheezing or anything, i just hope to god i dont have to go thru injection's again, specially with something that big haha

Yeh he is really blue at the moment, his usually MUCH lighter then this but at the moment he looks almost black
