About 2,000 years ago, a cat walked across a roof tile while it was still drying:

Recently, a team of archaeologists working along the route of a new road in Lincoln, England, found the tile among thousands of pieces of newly uncovered Roman-era material, Lincolnshire Live reports.

These clay tiles were made for the roof of a Roman house. They had been laid out to dry—when a cat sauntered by. A couple of years ago, a similar tile was found in Gloucester. According to the BBC, it’s not unusual for animal (or human) prints to show up on Roman roof tiles, but it’s rare to find one from a cat. Even 2,000 years ago, cats were fussy enough not to walk across wet clay, apparently.
