So, it was finally warm enough to let my 6 year old Herman's out for a walk about in the back yard, and what does he do?? He spends an hour or so hunting down and trying to eat the chunks of limestone that my snow-blower had tossed in there over the winter and I'd missed picking up. Is this a sign that I've messed up on his diet, or do I just have the tortoise version of that kid in grade school who kept eating the paste???
