I am going to piggyback on this topic, I was giving my boa a bath today since she is going into a shed, and I noticed this on her belly. I am not sure if its scale rot or just because she is gonna be shedding soon. I did look at th epics posted above, my snakes scales don't look like that, but I may have noticed the scale rot in a very early stage.
I tried to get good photo's.... I hope you can see the slight discoloration I am talking about. Since I am used to ball python's and my ball python bellies are completly white, th eboa's belly looks different. There is definatly brown discoloration present, no blisters or puss tho.

( i kno wthe black mark is her pattern coloration)

( this is slightly blurry)
I do plan on taking her to the vet soon reguardless of what anyone says. I do have a few questions tho-
1- should I wait til she is done shedding? I think it may be stressful to the snake if she's shedding. Her eyes were cloudy two days ago, now they cleared up, so I am expecting a shed soon.
2- I dont feed my snakes during the whole shedding cycle, so she is going to miss a feeding. Should the snake be fed b4 going to the vet so the snake is not hugry? if that's the case, i'dhave to wait atleast 2 days to see the vet.
Either way, she is going to go, but I am just wondering if its scale rot in the early stage and what I could do for her. Actually, I know what to do for her if you guys suggest it may be scale rot since I read the replies above. I am using cypress mulch for substrate since I am having humidity issues ( new cage is ordered, will be arriving in 2-3 weeks)
anyways, any feedback is appreciated! And I hope piggybacking is alright- I didn't want to post a new thread if there was a recent one just posted...
