I fed my snake a normal meal of F/T mouse about 3 hrs ago! He ate with vigor! But just now when I was about to go to bed, I decided to look in on him and found the below pic! It looks like blood tinged mucus running down the side of his mouth....He did open his mouth really wide while I was watching him, and apart from it being a bit mucusy(could be from feeding) there wasn't anything alarming.

Yesterday he was fine and I held him for a while.

There are no signs of an RI(clicking when breathing, always propping his upper body up against the rack, etc) and his temps are fine.

I know to take him to the vet, so please don't say that! I'm just wondering if anyone else has had this happen and what was the cause and outcome?!?

I feel so bad for him....and he's my favorite out of the bunch!
