Cats' food didn't come out of a can and it was nothing but the best fish - Pt Perpendicular, c 1936 / by Mrs Tulk, originally uploaded by State Library of New South Wales collection.
A photo from 1936 from the Commons area at Flickr - State Library of New South Wales. Shows a child holding a big fish tempting a group of cats. They noted that probably people wouldn't be feeding nice snapper to their cats today. We sure don't feed pets what they evolved eating these days.
