Gray tabby cat with blue collar missing near Montclair

I’m hoping someone in North Jersey has seen my gray tabby cat. Yesterday around 7pm, he slipped out the door on Church Street in Montclair, near the Whole Foods. He’s a medium-sized cat, about 10 pounds, with a blue nylon collar and a tiny silver bell. He has a few white whiskers and a small orange spot on his left ear — unique enough that people notice him. He’s usually friendly once he gets to know you, but he’s also pretty skittish, so please approach slowly. The cat means a lot to me—he’s been part of the family since he was a kitten, and I really need him back. If you’ve seen him or have any info, please text or email me. Any help is appreciated.
