One interesting discovery in the cat's rounds would be a small throng of strays that tended to congregate in the early mornings in one corner of the school. They all seem to mill about aimlessly. Or, perhaps, restlessly, as if waiting for something or someone to come by...

There. Those two shallow bowls of cat food were not there two seconds ago, were they? A blink is all it takes to miss how they arrived there, but there might have been the flicker of delicate fingers against a shadowy backdrop in the space against the wall as someone or something set the plates to rest.

It doesn't have to be explained how the mingling cats reacted to such a presentation.
