Hope you have found her and all is well
If you havent sit down somewhere quiet and relax and start thinking of all the tiny places you didnt look cos you thought they were too small, under cupboards, beds, sofa, between things and start at one end of house and shut the doors after you have looked.
Dont forget inside drawers and amongst anything soft, behind curtains or blinds.
Maybe in a bookcase, check any cupboards thatare closed.
Its very important to close every door after you have searched a room cos they can be so sneaky and slip out while your back is turned.
Once you have found her decide which places she can go and open up doors again.
