Why is my young cat vomiting, having diarrhea, and drinking a lot?
In order to get a diagnosis, you will need to take Blondie to a veterinarian. There could be many reasons for this such as pancreatitis, gall bladder disease, liver disease, toxin ingestion, metabolic disease, cancer, intestinal infection/inflammation and cancer. A vet would need to evaluate Blondie and doing some tests before it's possible to formulate an accurate diagnosis.
What you have described seems like rather severe signs of disease, so I recommend taking her to a veterinarian as soon as possible for treatment. She may be dehydrated, which can cause the signs of disease to be worse and may be life-threatening. For now, make sure she has plenty of water and is comfortable.
I hope that helps and Blondie gets better soon.
