i have a baby girl and an adult male.. they are both very very timid.
The female especially, shes even timid when eating.. very soft strikes... kinda funnny.
My male is a monster when he eats.. scares me some times but when they are out and being handled they are loves.
... the point im trying to make comes in here- I have a dog and i live with my grandma.
so my snakes love being handled but when other people and animals come around they get visably upset and nervous and agitated... that could be it.

hope this helps.. sorry to here about the agression problem
