Lost - British Short Haired - Grangetown/Leckwith area

Hi, our British Short-hair Brian is missing from the Leckwith / Grangetown area near Bessemer Rd market. He's grey/ lilac with amber eyes and some very faint rings/ stripes along his body and tail. He's 10 months old and inexperienced with being outdoors. He's much loved and we are desperate to have him home. Please help by checking gardens, sheds and any other enclosed spaces. If you see him please let me know: pen.tomkins@gmail.com
Thank you
