Two days ago my cat was vomiting everywhere but she was acting normal behavior wise. Yesterday we took her to the vet and they gave her a shot that I forgot the name of that helps with nausea. She also had some blood taken and they gave her some water. The vet called today and said her blood looked fine and everything was alright. Ever since we got back from the vet she has been laying in one sport for more than a couple of hours. She has ate once that my family knows of and has went pee/poop 3 times since then. In the past few hours she has also started to drool and I have never seen her do this before. Is she sick or can this happen after they are given medicine?
