Your cat needs to be examined by a veterinarian. Screening blood work will be run to rule out kidney disease, liver disease, hyperthyroidism, and diabetes. Hyperthyroidism causes increased thirst, increased urination, large appetite in the face of weight, vomiting, and behavioral changes. The problem could also be primarily with the gastrointestinal tract. Inflammatory bowel disease, lymphoma, and small intestinal bacterial overgrowth are a few of the problems that could cause these signs. Imaging (x-ray or ultrasound) may be needed to view the gastrointestinal tract.
