My poor baby is sitting in the vet's right now.

She's had diarrhea for about a week now but it was yesterday that finally got her to the vet. She started throwing up blood! I called as soon as I saw and they gave me an 1:30 appointment (I called @ 8:30) unless it gets worse. So I took her up there and she had a slight fever (102.5 F) and there were no obstructions that could be seen on x-rays so they kept her overnight. They are going to treat her for an ulcer. I've been waiting all day for them to call me. I hope it's nothing too serious. It broke my heart yesterday afternoon to leave her there.
