Reward! Missing Fluffy Grey Tabby Cat

Domestic longhair mix - looks like a small Maine coon but he’s mixed with Siberian actually. He’s around 8 years old, raised him from the bottle. Grey tabby with a mane and slightly fluffy tail. Bright green eyes. He rarely goes outdoors but when he does he ALWAYS comes back within an hour or so after watching bunnies. I’m very distraught and offering a reward for his safe return home!
