Poor Ellie! I see that she isn't spayed. When cats aren't spayed, they can be prone to a life threatening infection of the uterus called a pyometra. This would cause her to vomit, not eat, and not drink. Other causes include a severe GI illness, eating something rotten, pancreatitis, or a foreign body. Given the risk of a pyometra and the fact that she isn't eating, drinking, and keeps vomiting, my recommendation is to have Ellie seen by a vet immediately. The vet can do a physical exam, blood tests, a urinalysis, and possibly x-rays to diagnose what is causing her symptoms so she can be treated. She likely needs a shot to stop the vomiting, and IV fluids for hydration along with any other treatment the vet deems necessary. If she does have a pyometra, spaying her is one of the recommended treatments. Please take her into a vet ASAP.
