My cat escaped

My cat escaped yesterday around 62nd and Western. He's exclusively an indoor cat, no collar or chip. He doesn't know the area at all, and he was scared when he ran, like he shot off down the direction of 63rd. I've been all over the neighborhood calling for him, no luck. I've posted on nextdoor and okc lost and found. I'm putting up signs tomorrow evening after work. I hope he gets hungry and starts bothering someone for food, and they see he's a missing pet.
