you can find stuff on what the greenish blue feces actually is...I forget....infections of some type they say....
....I saw it for 20 years....all shades of green and blue...not always....just here and there.....never bothered me....or them I guess.....there have been talks on it here on Kingsnake before....some people say Vet vet vet...I say...the snakes aren't worth what a vet trip costs...kinda callous....but true....it wouldn't matter IF vets did the miracles people think they can...but most vets just gues on snakes and charge for it....we can guess a whole lot better on here if people would just post good pics....

...good luck.....he'll be fine....
