A person from one of the many places I posted online saw her in their apartment complex and called me. When I came to get her she was huddled in a hole next to a drainage pipe, I'm assuming hiding and keeping warm. Luckily her lead leash was still on and trailing perfectly out the hole for me to grab and I was able get her from the hole and take her back home. I'm relieved beyond relief and heartened by all the help and resources made available in such short notice!
