Well, the parapets are up high, so the kibble for them has to be up high too. You wouldn't store the food for a pet far from where the pet is, that's just silly. So, you move along the empty corridors of the castle until you find a way up into the attic, which you find locked and barred, with a sizable demon stuck behind the bars. The demon asks politely if you could maybe let it out because it's been so lonely here. Loneliness is really a terrible sensation, but you also figure maybe there's a reason why the demon is locked here? Hm.
