sniffling? this is concerning. i am by any means NO expert but for me personally this isnt somthing i would take lightly at all.. right away it makes my mind go to two different places. AND this is not a diagnosis just right where my mind goes if i was in your shoes
1. she could have inhailed water from the
bath and shes trying to get it out
2. id be worried about a respitory infection.. it would explain the not eating or basking part as well. have you tried listening to her breathing? ive read theirs often a popping noise or even bubbles that come out of there noses.
keep a close eye on her, and if shes still doing this sniffling i would strongly suggest you get an appointment with an exotic vet because worse comes to worse and it is a respitory infection she needs QUICK care.
and try your best to do your research about the vet before you go.. i myself just had to pay an exotic vet a visit for my baby boy and although doc was labeled an exotic vet.... he sucked and wracked up a huge probably unnecessary bill and we still have no diagnosis just something it could be .
best of luck!
