Our cat Sousa has been sick lately. He caught some kind of upper respiratory virus when Dad took him to the vet for a checkup, and he's very reluctant to eat or drink anything. He fought back more tonight, though, when Dad gave him his eyedropper-full of preventative antibiotics (and several of water), so I think he's getting a bit better. We're still worried about him not eating, though (his nose is stuffy so he's reluctant to eat what he can't smell) -- too many days without food is not so good for cats' livers, and his test results from the original checkup were a little off.
Poor kitty... *sniff*
