Snake attitude? (Bad one)

[gwynhwyfar]

Nothing's changed as far as her environment -- same temp, same sub, same basking rock, same dish for water. She's still eating (she's eating more, but I figure that goes along with getting bigger).

Oh, and she's sirtalis. Common eastern gartersnake.

I deal only with radix. Can't make to many comments with regards to keeping sirtalis. I'm sure someone else will be able to give you some other ideas more tailored to them.
Does the attitude change the longer you hold her? Sounds to me like she doesn't want to be touched. Doubt if it's mental sound more physical. Like being held hurts. Just an observation.
Wish I could help more.
