Ordinary Athians built these monuments to the Tantas' adorable catlike familiars.
They were erected in places known to be frequented by these much-loved beings, and it became common for adoring pilgrims to leave various foodstuffs and treats as offerings at the statues' feet. The Tantas were unhappy at this waste of valuable resources, and eventually inscribed warnings not to feed their familiars into the statues themselves.
