Ruby passed away on 15th February 2017 at about 1:10PM. He was about 10 years old.

He arrived on our front door about 6 months after we moved in (2008) and stayed. We found his original owners but he wasn’t impressed when they called to collect him and he decided he wanted to stay. Ruby usually got his way.
