Lost orange tabby cat named Pumpkin with distinct stripes and a small white chest patch in Elmwood Village, Buffalo.

I lost my beloved orange tabby cat named Pumpkin on the evening of October 10th in the Elmwood Village area of Buffalo. He’s very friendly and loves to explore, but he usually doesn’t wander too far. I last saw him near my backyard, and I'm worried about him. He's about 3 years old, medium-sized, with distinct stripes, and has a small white patch on his chest.
