Just to report a new and completely different tabby has appeared today and is cold, hungry but unaccountably friendly - as if it thinks this is its home. It was sitting on the garden bench and seems like in no hurry to leave. We've fed it and if it still there after I return from work, will put a photo up. If you think your cat is missing, please let me know.
ps pleased to meet Catherine and hear of the safe return of Bonnie and Cedar Door's detective work was a great read.
