Yesterday afternoon Mark dropped a piece of tuna on the ground - Boo was twining between his legs and, as near as he could tell, begging - and she jumped on it. He then gave her half the can, which she ate. This is remarkable because she's pretty much always turned her nose up at absolutely everything besides her chosen brand of cat food, and by everything I mean all meats, cream, and canned cat food.
And I know this isn't the most exciting thing in the world and indeed is the sort of news only of importance to parents and worried pet owners, but for the first time in five days there was something in the litter box.
At present, I'm letting her have all of the tuna she wants. When she gets her appetite back, then we'll see about getting her to eat the kidney diet food.
