Missing Black and White cat

Harry, our black and white kitten has gone missing from Binn Eadair View, Sutton, D13. He is male and ~6 month old. He wasnt allowed outside as was supposed to get neutered this saturday but he sneaked out yesterday afternoon and has not been seen since! He was a rescue kitten so he is still rather slim and also shy with strange people. PLEASE help to find him! REWARD for those who return him home.
