Found this on the BBC re a red squirrel boarding a cruise ship... have yet to discover if he got off or not!...Squirrel 'stowaway' on wildlife holiday cruiseEfforts are to be made to capture a red squirrel found on a wildlife holiday cruise boat.
The "stowaway" was thought to have fled to The Majestic Line's Glen Massan vessel following a territorial dispute with another squirrel, or being frightened by a bird of prey.
It has been on the Heritage and Wildlife of South Argyll Cruise since Monday morning.
The squirrel was spotted after the boat anchored in Loch Riddon.
It was first sighted by Canadian professional photographer Steve Boyton...
