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.

    It's not very common for a human to give a cat the flu, so this may not be the likely cause of her being sick. I see that Mamma isn't spayed, and intact females can develop an infection of the uterus called a pyometra. A pyometra is fatal without treatment and would cause her to not eat. There could be another medical cause behind her not eating and drinking, and I can tell you it's extremely serious she hasn't eaten or drank in two days. When cats do not eat going on 72 hours, they develop a fatty liver which is fatal without treatment. In this case, her symptoms are a medical emergency and she has to see a vet now to avoid developing a fatty liver. The vet can diagnose what is causing her symptoms and the best way to treat her. Please take her into a vet immediately.

    I'm sorry Ruby isn't feeling well! While this vomiting could be caused by a GI illness, I see she isn't spay. That makes me concerned she could be suffering from a pyometra, which is a life threatening infection of the uterus. A pyo would cause her to stop eating and vomit, and it is fatal without treatment. Because I can't see her in person to rule out a pyo, and taking into consideration the seriousness of a pyo, Ruby should see a vet immediately. The vet can do a physical exam, blood tests, urinalysis, and x-rays to diagnose what is causing her vomiting. If she does have a pyo, spaying her is part of the recommended treatment. Please take her into an ER vet clinic; if there isn't one in your area, there will be a vet on call for emergencies. The information to reach that vet is found on a clinic's answering machine or website.
