I know that cats are finicky but I think that my kitten has me wrapped around her little paw. It is a ritual as soon as I wake up in the morning, i have to fill up her food dish and change her water. It doesnt matter that her food dish will be half full from the previous day and the same with her water but she wont drink her water at all unless it is fresh in the morning. She will nibble at her food a little but mostly she will follow me around the house rolling around on the floor making loud purring sounds and soon as i change it she meows a couple times and is happy the rest of the day. I guess they are creatures of habit.
