Kat's cat, our cat, has anxiety issues involving food. I know this because I work with people every day who have anxiety issues involving food and the symptoms are there. He fixates on the food bag, sometimes rubbing up against it with his chin. Immediate hovering whenever anyone goes near his food. He's used to getting the water from the tuna can, and also getting milk whenever anyone has cereal, so he makes his presence known (and will frequently trip you) if you have either items in your hands. And all these are pretty easy to deal with, really.
It's when he can see the bottom of his bowl that he begins to get *really* concerned.
And that usually happens around 5 am.
Very early in the morning, he will notice he can see the bottom of his food dish. At which point, he will scamper up onto the bed and promptly sit on my head, meowing.
Does he do this to Kat? No. Kat is the deepest sleeper I've ever encountered. She's sleep through the apocolypse. At least, I know she can sleep through the occasional late-night opening of a pint of Ben and Jerry's Cherry Garcia Ice Cream. So her deep sleeping can cut both ways.
Anyway, Sylvester, the molester of my sleep, will continue to harass and pester me until I get up and refill his food dish.
But here's the kicker: The dish is invariably still half-full. He pushes the food around as he eats it, and half of the stuff has gathered up around the side of the bowl. The situation is far from critical. Rations are still present. But try to explain that to any cat, let alone a cat with food anxiety.
