In two show they are talking about a meal called "cattery", which seems to be something for breakfast. I´m not shure, how to write it right, so i wrote it how i hear it. I doubt, that this is a translation mistake, because we don´t have a word like this in german.
Using it the way i wrote it, Google shows themes about cats, but i can´t believe, that they eat cats for breakfast

Can someone shed some light on this?
Oh btw - no spoilers please
