Thank you both for the input; I hope they'll accept a volunteer, and printing off the care sheet is a good idea too. I'm just afraid they'll either be suspicious of my motives for helping, or take it as some kind of affront and refuse/not listen on principle. I'll do my best to be tactful, as you say -- all I really want is for these poor little snakes to have a fighting chance and happier, healthier living conditions.
