Cat slipped out, Didn't know for hours. Ended up gone a week. She is now under house and will not come out except at night, Cannot get near her. Putting food under there and she is eating. PUT More food on porch close to door. She is so fast cannot catch her. She seems very scared of us and has always been very loving. When we first got she hid three days before trusting us. How can we entice her out and back into house. She has been inside for year and a half.

Contact your local shelter or vet and see if they have a live trap you can rent or borrow. Put food in the back of the trap and wait.

Is she fixed? How long has she been under your house? If she's been out for more than a couple months and isn't fixed, then it's possible she has kittens under there.
