Okay so to make a long story short we recently took in a cat for a friend who couldnt keep her anymore. She has had one litter already around 6 months ago. We've had her for around a month now and shes been showing some signs of pregnancy(enlarged nipples, tight round stomach, and today shes started acting as though she doesnt feel good and even threw up this morning). They were going to get her spayed but hadnt gotten to it yet and our vet said they couldnt tell for sure(they palpated and did an x-ray but said they wouldnt see anything if she was under 45 days along). Basically I'm just worried she might have something else.
