My cat stopped eating and drinking. Is this a sign of a serious illness?
I am sorry to hear about Annabelle. If she is not eating and now not drinking these are definitely signs of concern that require evaluation by a veterinarian. In particular, if she is an overweight cat (it says on your information that she is 14 pounds) then she is at risk of developing a dangerous liver condition called hepatic lipidosis if she isn't eating. There are many possible underlying causes for her symptoms, including primary GI disease (such as inflammatory bowel disease, gastritis, stomach ulcer, gi tumors, gi infection, pancreatitis, cholangiohepatitis) or disease of the liver or kidney (either of these can cause increased thirst). The vet will want to do an examination and will likely recommend bloodwork and an x-ray to try to determine the cause of her symptoms. She may need to be prescribed an appetite stimulant, and may need fluid therapy if she is dehydrated.
