If she has not come out in an hour or so, give her something to "hunt", and she will come out to play. I use polyester ribbons about 1/2" wide and about 3 ft long, with a knot in the "hunted" end. Reach down and gently tap the floor or piece of furniture to get her attention, then it slow and twitchy. If her new home has a potty box, food, and fun, she will settle in quicker. Remember that things that reach over a cat's head are usually trying to "eat" the cat. Reach toward her from the side so she sees it is you. Grabbing cats to catch them makes you scary, be soft handed.
