Our female cat (she just showed up about 5 weeks ago) is pregnant. It was pregnant when it showed up, or else we would have spayed her immediatley. Today I let her into the utility room for a few minutes, and when I went to go get her, I found that she had thrown up, and done a mix of diarrea and solid poop. Also, where it become more liquidy, there was some blood. Is there anything to be worried about? Does this mean she's about to go into labor? Her nipples are vry swollen, she's quit large int he abdominal area, and she's been eating a ton. However, she's not meowing like crazy like most people say their cats do before labor.
