My (our) cat, Jethro, arrived with my wife some years ago. She'd got him from Sheffield, and was a vegetarian at the time. Pretty soon, Jethro refused all cat food because, apparently, mum had something much more interesting... for three years, he lived on chickpeas, lentils, and aubergine bake, and was known on several occasions to bring a late-night present of a freshly dug carrot home. (mrooowwwwrr.. meeoowwwrrrr...).
