My Silver Kitty Is Sick

I feel:: crushed

I had to take her to the vet this morning. Last night she threw up some clear liquid and she acted like she wasn't feeling well. Today when I woke up, I found some brownish-green mucus on the floor that smelled really acrid. The vet just called and told me that she is running a temperature of 105. That's really high. I'm supposed to go back there at 4:00 and talk to him. He said that he was going to take some blood and run some tests on it and that he wants to make sure that her kidneys are functioning properly. I'm so worried about her.
