well she used to seem to enjoy having underneathe her chin rubbed but now she wont let us near it, its only every once in a while that i hear a crackle and when i did try to look was just the area where her tongue comes out that has gotten slightly discolored (like a grayish color). i cant see any lesions or red dots or blood coming through like they say on the sites i checked out on snake diseases, theres also no blowing bubbles or extra saliva or anything like that, its just the discoloration int the tongue part of her mouth and thecrackle every now and then and the fact she doesnt seem to be as friendly as she used to.
