Missing Sept 2015, Downend, black and white cat,

Missing Lucas from bs16, Downend. Lucas has been missing since end of July. I’ve held off posting as he has previously gone missing but always turns up. I’m now getting increasingly worried as this is by far the longest time he’s been gone. His brother never goes anywhere! All the local vets are aware & rspca. Lucas was wearing a red collar & id tag, he’s small, black & white and very friendly once he gets to know you. If you have seen him please let me know. In the 2nd pic Lucas is on the left, he’s short haired unlike his brother Vinnie. Thank you for any help.
