well her last shed was 1.7.09 and I do not recall hearing this squeak right after, I guess it could possibly be skin but I am taking her to the vet anyway just to be safe but and I also want to have sexed because I was told that she was a male but I have correctly popped her several times without revealing any hemipenes. but I would like to know if anyone thinks I should switch subtrates? what would help hold humidity most?
