Has she always had this smell? Some snakes are more nervous (& prone to musking) than others, & I could see it when she was newly-arrived (especially assuming she
had been probed prior to arrival at your place?) but 6 mos. is a long time for it to be normal & stress-related, IMO. I think it's very possibly an infection...some ppl aren't
as careful when probing snakes as they should be...I think a vet visit might be a good idea. It's not normal, albino or otherwise.
