I was given 3500 Years of the Cat In Art for a birthday present. I only mention this because it's not the sort of book I'd have thought of buying myself, so it was a delightful surprise to discover how good it was. I thought I'd probably just flick through it, because the illustrations are certainly beautiful, but there's a really interesting introduction that discusses the cat in its historical and cultural context and made me keen to read the rest of the text as well as admire the pictures. Subsequent chapters don't just take you on a trot through the history of the cat in art, they focus on themes such as The Comic Cat, The Portrait Cat and The Eastern Cat.
Obviously cat fanatics will love it, and cat AND art obsessives will have a ball - but I'm neither so I really recommend it to the more general reader too.
