I fear my Moonie is dying

Thursday I woke up with my black Solomon Grundy cat (aka "Mini," "Moonie," "Nolomon Newly") sitting sluggish and catatonic by the water bowls. She moved around to various spots during the day, but never acknowledged me, though I stroked her. She had something white hanging around her mouth; and she threw up at least 3 times that I saw, a couple of times with small clumps of gray matter in mainly clear liquid. I couldn't tell what the "gray matter" was.

Friday, same thing.

Saturday, she finally jumped up on me while I was lying on the couch, and went to sleep on me and let me stroke her and sing her song ("Solomon Grundy / Met you on a Saturday / It was a rainy day..."). During the day, I tried putting food dishes right in front of her, and tried adding some tuna treats to her dish (while keeping the others away). She still didn't eat.

Today, Sunday, I saw her drink water. But not eat. And she's skin-and-bones. But she is affectionate with me, and she is now, finally, again acting interested in what the other cats are doing. A good sign. (And she just now jumped up in my lap as I'm typing.)

But you've got to eat, my Moons. Don't be that lamb in the Ted Hughes poem that just didn't want to live!
