Aloha! You're speaking with Dr. Michael Salkin
Hi - Vomiting - or any symptom - that lasts that long in such a geriatric cat is worrisome. There are quite a few possible etiologies. He may have accumulated more non-digestible ingesta in his stomach (hair, debris) than usual; he may be experiencing a bout of inflammatory bowel disease (IBD); he may be suffering from a major organ disorder - pancreatitis, hepatitis and nephritis can all cause nausea. Unfortunately at his age we have to worry about malignancies as well - solid tumors of the pancreas and GI tract such as an adenocarcinoma or mast cell tumor - or infiltrative cancers such as lymphoma. He may be hyperthyroid - a common disorder at his age that causes hypermotility of the GI tract. As you can see there are a few too many things that can be going on so it frustrates me that I can't be more specific for you. I wouldn't wait much longer to have Pounce seen by his vet who most likely will want to run a senior/geriatric panel (blood and urine testing) on Pounce.. Everything can be serious at 14-16 years of age. His loss of voice may be from oropharyngeal and laryngeal swelling secondary to acid reflux into those areas. Please respond with further information, questions or concerns if you wish.

He is not drinking excessively, would any of these symptoms cause a cat to want to drink more?. He has not lost his appetite, dry food is not his favorite at this moment.
Expert:  Dr. Michael Salkin replied 5 years ago.
Drinking more (polydipsia) is a warning sign for diabetes, hepatic and renal insufficiency, urinary tract infection and the very rare Cushings. The fact that he's NOT polydipsic and still eats well is a wonderful finding. It still leaves disorders such as non-food irritation of the stomach, IBD, mild pancreatitis, malignancies and hyperthyroidism on the list, however. Hyperthyroidism usually causes polyphagia (increased hunger) but weight loss - neither of which you're seeing. 10% of our hyperthyroids act like hypothyroids though - sluggish, weight gain...those cats will fool us until we test them. Please continue our conversation if you wish.
