I have two 2 year old sulcatas that have gone underground and i cant reach. they are healthy and about 10 inches long. i was planning on bringing them inside before it got too cold, but now they are burrowed in, i usually get them to come out by knocking on their food tray but it is not working now. the temp has been between 38-70. i question if i should dig them up or wait for a warm day for them to come up. live in el paso tx. thanks, tczar
