Steve Haywood 
Too Narrow to Swing a Cat [EPUB ebook] 
Going Nowhere in Particular on the English Waterways

She was particularly taken with the small narrow ledges that ran along either side of the boat. For a cat, four inches is an airport runway – she could dance a Moonwalk along them on her two hind legs, juggling at the same time.
Steve has a new member of crew aboard his narrowboat, Justice – but maybe not the kind he’d have wanted if he’d known the trouble she’d cause. Kit, an untidy bundle of fur with all the attitude you would expect from a ‘sarf Lunnun’ cat, joins him on a mission to discover lost parts of England. Steve gets a different perspective on the modern world as he cruises the canals through a landscape unchanged for centuries, visiting picturesque towns and waterway festivals along the way.
