Rocket, my very fluffy tabby cat snuck out of our new house in Cyncoed

Rocket, my very fluffy tabby cat snuck out of our new house in Cyncoed this morning. He's a long haired tabby with white feet and belly, a very bushy tail and quite dark down his spine. We moved here on Monday so he's very nervous. Generally he won't approach strangers but when befriended is incredible affectionate. 
Please let me know if you spot him anywhere, or try to bring him inside if you find him. He's currently not chipped or wearing a collar. I had planned on putting a named collar on him for when I let him out. 
I'm sarah, please call if you find him. 07711220997
