My cat, the yogurt fiend.

[kiya]

From a blow-by-blow account of Arthur vs. the empty tub (just my comments):

Whitney gives Arthur the more or less empty yoghurt tub. He solemnly licks it across the floor.
Whitney hee hee. Now he's likcing it in the other direction.
You say "Now he's hooking a paw into it so it'll stop running away."
Whitney will have to remember to do this when she finishes yoghurt in the future.
You say "He's now tipped it over, and is trying to deal with the fact that it slides when he shoves his nose in it, and rolls when he slurps it."
You say ". . . he just picked the tub up in his teeth, walked backwards onto the carpet, and dropped it."
You say "He's now sticking his paws into the tipped-over tub to try to induce the remaining traces of yoghurt to come out."
You say "He's now licking his muzzle with Remarkable Thoroughness, I presume because he used it to scrape off more yogurt."
You say "It occurs to me that the entertainment value of watching Arthur with the tubs may actually remind me to eat the damn yogurt more often."

That last was because I realised that I'm strongly tempted to go eat another tub of yogurt to watch another episode of Arthur vs. geometry, but we don't actually have any around for me to do this with, so I can't.
