I only have 1 that is not completely head shy.. all of mine u can touch their heads but not like how you can with my pinstripe.. hes the most laid back snake ive ever seen... u can actually grab his head and move it and he just looks at u like do it again!!! and puts his head back into your hand.. but when my one snake had an RI, we went through and checked all the snakes mouths to make sure they didnt have the starting of the infection and we didnt even have to hold him behind his head.. we just took a wooden dowel thing and just opened his mouth and he didnt even care... hes a very special boy haha
