Our cat has stopped eating, so I took her to the vet, where I discovered she's only about 4.1 lbs even though she'd been eating well until Thursday. I turned down the expensive tests to find out why (she's 16), and asked for subcutaneous fluid and a few appetite stimulants. That has worked in the past when this happened (late summer, always at the lake house). Vet said give her anything to eat you normally wouldn't just to get some calories in her. So, this morning in addition to baby food she got some Häagen-Dazs ice cream and salmon meant for people. She'll get a little freshly cooked chicken and steak later--after she wakes up.
