Gray tabby cat with green collar, Brighton

I lost my gray tabby cat yesterday around 3pm near the Royal Pavilion gardens in Brighton. He’s a gray tabby with a white bib, white paws, and a tiny notch in his left ear. He wears a bright green collar with a tiny bell and is microchipped. He's a bit shy with strangers but incredibly loyal, and this loss has me anxious because he's been with me since last year—this cat is my emotional support and I miss him terribly. If you’ve seen him anywhere around the Old Steine or West Street, drop me a message here—I'm really hoping for him to come home safe.
