My cats are free fed, so there's really no "ritual" per se.... But if they're feeder thingy is empty, BOY do I hear about it! I go into the kitchen in the morning and I've got at least 5 cats SCREAMING at me!

"Food! We're hungry! We haven't eaten in HOURS!" rrreeeoooowwwwrrrrr..... mew mew mew..... MEW... RRRREEEEOOOOWWWWRRRRRR..... MAEW MAEW....

Then as I go into the other room to get their food i'm tripping over kittens, usually have Hector attached to my leg (thankfully I wear long sleeping pants!), then they climb the bookshelves and stay there hollering until I stumble my way back to the kitchen.
