Concerned about his breathing, I called this morning and made an appointment for this afternoon. I just got back from the vet's office.
Xrays were taken and she couldn't see anything. She drew fluid out of his lungs, which she showed me. Pink. Very, very pink. It looked like strawberry Quik. And there was a lot. She had weighed him before the fluid draw and again after. She pulled off over a half of a pound. She told me she'd never gotten this much fluid from a cat who wasn't blue (no oxygen, I guess).
We made an appointment for tomorrow morning and if he's gotten really bad overnight, we'll be saying goodbye.
She said what may have happened is with the lungs opening up with the fluid being reabsorbed after the Rutin, that it's quite possible the suspected cancer or tumor said "wow, look at all of this room I have to grow". And it grew.
I really wish I was optimistic about his chances, but I'm not. Stuff just doesn't work that way.
I'm going to go take his picture now. I'll take a bunch. And I think I'm going to cry.
