Londynで迷子になった＆見つかったペット

Hi pls help to find my cat Mishelka has yellow collar

My 2 year old boy Witcher has not returned since 2/13/2023. 3 weeks ago we moved into a new house and after 2 weeks spent at home to acclimate Witcher left and has not returned yet. We miss him very much and are worried because he did not know the area well. If anyone sees him please contact me. Thank you
