So from what i've read beyond instinctive "emotions" such as hunger, fear...

I don't think they develop any affection, just tame from being used to being in contact with us.

What i want to know is your opinion on the snakes forming habits?

ex: almost every time i feed my normal girl she drags the food into her water.

When i come home and sit at the desk she's on top of she comes out of her hot hide to the glass, looks around at me and then into the cold hide.
