found this little one in my yard, and want to know if i should be alarmed. he does not seem to have venomous traits, non viperous eyes nor triangular head. but i would like to be sure. i plan to set him free, but maybe keep him as a possible pet. i have several reptiles already and wouldn't mind caring for him/her but that would be only if it could be tamable and non venomous. what are your recommendations. what kind of snake is it?
