It's hard to proof that an animal understands time, without that animal understanding numerical values of time. Our dogs and cats certainly know when a short duration of time has past but they have no idea what 5 minutes means. I can tell my dog to 'stay', and he'll show a basic understanding time passing. If I tell him to count for ten seconds and then come to me, he'd be screwed. But counting and math are two diferent things.

This is a perfect opportunity to post some hoochie poochie, cuddly wuddly stuff about how cats actually look like little bears, how they are just little furballs, etc. But I would never post something like that. I'm just sayin'. .....But I think the cats over here have a sense of day and night, their stomachs run on a little clock, at least. They know they get fed their "cat food" in the evening, so in the daytime, they are out hunting bugs and things and chewing on the front lawn. They hunt natural snacks, so to speak, when the sun is up. The the sun goes down and they are all ready to eat their human-made fish flavored cornmeal, their crunchy polenta or whatever you want to call it. They have a routine.
