This fellow answers to the name of Gibby. Presumably took one look at The Astcote Arms and decided that was preferable to the bread and water he got here. It's a fair distance, though, so if you happen to see a Gerbil hitchhiking, do stop for him.
You might also mention that there's now a lass called Phoebe in his bed . . . if you also mention that there's a large cat called Jet where he may be thinking of heading then one of the two thoughts may tempt him back!
