Why is my senior cat vomiting and not eating after vet visit?

Pet's info: Cat | Domestic Shorthair | Male | neutered | 14 years and 5 months old
My 14 yr old cat was in to see the vet this past weekend. We thought she had lost weight but in fact was normal as was his bloodwork. He was prescribed 2 tablets of Cerenia 16 mg for vomiting. 10 minutes after swallowing the wet pill he vomited. He has not eaten anything in the past 2 days. Water is being thrown up. His vet said he was in good health but we are concerned about his not eating even passed up his favorite, tuna. Any suggestions,?

Persistent vomiting and refusal to eat is concerning, especially in an elderly pet where they may be weight loss or dehydration. Given the clear blood work i would be concerned about a possible obstruction, hairballs, tumours or a twisted bowel are all possible. Xrays may be recommended as well as tube feeding to maintain calorie intake until a diagnosis has been reached

Ideally, Baxter needs an abdominal ultrasound. If you cannot afford further diagnostics, your options are limited to treat him for suspected inflammatory bowel disease or cancer with prednisolone and mirtazapine. Discuss these medications with your veterinarian.

I think Pepe needs to go back to the vet for more diagnostics. It's good to know that they ruled-out organ failure and infection, because that will narrow down the problems to search for. I would want to take x-rays and scan the abdomen with ultrasound to check for signs of an obstruction or cancer. Both can cause a decrease in appetite and vomiting. What's most worrying right now is that he's not drinking. Dehydration can happen quickly in these cases and would be the most immenant risk to his health at this time. For this reason, I reccomend taking him back to the vet within the next 12 hours. I hope that helps and Pepe gets better soon.

I am very sorry to hear that Your cat is experiencing these troubling clinical signs. Unfortunately in elderly cats vomiting, weight loss and changes in appetite and drinking habits could be the first signs of potentially serious medical Conditions, which require bloodwork and a physical exam by your vet to diagnose. Because these symptoms have been noticed over a week period, I would suggest scheduling a visit in the next few days. If Your cat becaomes depressed, has difficulty breathing, or collapses I would take him in immediately. The vet will test for common metabolic diseases of elderly cats such as kidney disease, hyperthyroidism and diabetes, and may want to perf advanced imaging of the chest and abdomen using an X-ray or ultrasound to check for masses, intestinal blockages, and foreign bodies. I hope that this was a helpful answer, but more Importantly I hope Your cat starts to feel better soon. Warmest regards to you both.

Yes, I would be worried. Vomiting in elderly cats can be a sign of a medical illness such as kidney failure, diabetes, hyperthyroidism, or even cancer. I'd take her into a vet today for a geriatric blood panel and urinalysis. Based on the results of the tests, the vet can discuss treatment options. I hope this helps.
