I took my kitty to the vet this morning . She threw up that rubber band but I cant tell if she has gone to the bathroom because of Remy. She has thrown up everything she has tried to eat. They are keeping her there for observation. They did xrays and blood tests and she was dehydrated. I am supposed to bring her home today . But I didnt think anything would show on an xray unless it was metal? So if she has a blockage, how can they tell? I am a wreck!
