Sprinkle litter from her litter box around your yard. That's worked like magic on some of our missing-cat-moments. It's like a big beacon saying 'THIS IS YOUR HOME'.

I don't remember the exact number but I think it was 80% of cats do return and the average time is 5 days. Our indoor cat went missing for 8 days and I'd given up on her...I bawled when she came home. I think she got trapped in someone's garage when they left for spring break or something.

Good that she has a chip.
