Very good news that you saw her alive!! But the poor baby is probably so scared that she doesn't dare to come out...

Catty1 has given great advice to get her back, and I hope Tricky will decide sooner or later to leave her hiding place and come back to you. Does she react to catnip? If so, you could try that as well (Lily has once left our apartment and ran into the stairway, but when I offered her her beloved catnip, she made a quick return).

Dear little Tricky, please get over your fear and come back home!!
