Orange tabby cat with blue collar, lost near Princeton

I lost my orange tabby cat with a white bib yesterday around 6pm near Nassau Street by the Princeton University campus. He's wearing a light blue collar with a small brass bell, and he has a tiny notch on his left ear. He's usually very friendly but will hide from strangers, so he might still be afraid if you spot him. This cat means a lot to my family; my daughter is worried and keeps asking about him. If you've seen him, I'd really appreciate any help in bringing him back home.
