Help Find Nala: Lost Shy Cat - Reward Offered!

Hi I'm looking for my kitty cat, Nala. She's an indoor cat although she likes to go outside once in a while for an hour or so. I let her outside around 3am on Sunday 5/5, never returned home and I haven't been able to find her in her usual spots.She's shy, skittish but a lover kitty. I'm offering monetary reward for bringing her back home with me. Last seen : NW Pettygrove and NW 24th Ave 650-339-1256 Thank you
