So..Six days ago I got a new baby female ball python in which I have named Aaron she is very pretty but I have a problem. She has very bad mood swings i have not touched her but I do stick my hands in there twice a day to change the water so that she always has something fresh to drink some days she will be extremely mean and hiss she even bit me once and other days she will just sit there and move her head along with my hand or just be really calm she is a very good eater the humidity is right where its supposed to be she has two hides and a heating mat everything she needs I have pretty big enclosure. I got her from my local pet store which is 3 hours away from where I live I know its bad to get them from pet stores but I cant have animals shipped to where I am due to many differing reasons and there are no pet expo's around at all when we went to go get her she was very rude to the petsmart employee I just need some tips is this normal or not and how should I get her to be a little less defensive am I doing something wrong? I just need some tips on how to tame her down a bit I have already but a scrap piece of clothing in there with my scent but I just need to know how to handle her I am not scared of her biting me more of I am scared she is going to bite me and im going to jump or get startled and hurt her.
