Milksnakes are notorious escape artist...I got my first one, got it home and within an hour and a half it was gone, never to be seen again...the next one I got, (not right away) I am OCD about making sure the lid is on tight (the first one escaped through a tiny accessory wire hole in one of those exo-terra tanks. And the girl doesn't disappoint, while she never has escaped, that is her daily routine...testing, looking for a weakness.... Hope you find her follow those threads you were given and hopefully it'll work out.
