Great looking snake you have there, I have what I think is a albino male pacific gopher around 1200grams. Who knows how old, he is the calmest snake ever, you cant get him to bite or hiss, My 2 year old holds him. I tried one day for about 45 mins by restraining his head lightly, jerking my hands around in front of the strike zone-nothing. Foods a diffrent story.
I am not sure of his orgins or if he is even pure. His pattern and color say Pacific not San Diego, but I have no clue. Finding a lone adult female is never easy. I will post a picture of him tomorrow. You tell me what you think.
