My cat waits patiently outside our door each morning so the first thing I hear is her desperate scream for food. She can open the door, she knows where we sleep, she has no problem barging in, and if I get out of the room before she gets there for any reason, she will instead ignore me and wait for my spouse to open the door.

If I put her food out while she's waiting, she won't eat unless I physically move her to it because I've broken the ritual of her greeting me in the morning and screaming at me while I make her breakfast and now she must try again.
