A sample of children's drawings — family, house, dog — each also depicting...The Creature.
In the small town's human ecology the Creature more or less replaces the spot taken by house cats elsewhere.
They are fluffy, and love to hunt rodents and insects.
It is unclear if the creature is single or plural: several instances of them have been noticed at the same time, but their number varies, and they seem to share their knowledge.
Some households still have cats and the cats don't seem to care: there is no direct competition between the two. It's just that most families are not interested in housing cats since the creature is already here.
They don't seem to multiply or to expand beyond the town's population center.
People joke about the creature being an ancient evil hiding in plain sight in a remote location, but the evilness has never been observed, or at least nothing different from a standard cat, and the city is not really isolated but just a lazy suburb.
