Oh man, hoggies are definitely smaller and more difficult. Best to check out small/tight spaces. If it's a bit colder where you are a heat source from your home would be a place you should check regularly. Make sure you leave a dish of water out so they can hydrate, and maybe put some flour around the bowl on the floor to see if the little one has ventured to it or not. Evidence helps with hope!
I've had a corn escape and found her a month later in one of my plants....book shelves are a common spot too. Close off any cracks under doors and anything else, and try to make the room escape proof! Best of luck.
