Lost Pet: KitKat

Circumstances

She broke through the screen on my patio when she saw another cat and took off chasing it. I have set out a blanket with my scent on it, food and water and I?m leaving the sliding door open enough for her to come in. I?m just so devastated that she?s gone. She is strictly an indoor cat. She is about 10 pounds. Thank you for any help.
