My senior cat is throwing up and won't eat. When should I see a vet?

Updated On September 23rd, 2025

Pet's info: Cat | American Shorthair | Male | neutered | 15 years and 10 months old | 13 lbs

My cat ate his breakfast and dinner yesterday and puked it all back up and did the same this morning but when it came to dinner time he wanted nothing to do with his food. He spent the whole day in front of the storm door in the sunshine

Poor Rascal! I see he's a senior cat, and in cat his age, this vomiting could be due to kidney disease, diabetes, hyperthyroidism, or even cancer. I would have him seen by a vet tonight to have a physical exam, geriatric blood panel, and urinalysis done. Whenever a cat has been vomiting for more than 24 hours, especially a senior cat, it's very important to have them checked out by a vet right away. Using the tests I mentioned above, the vet can diagnose the cause of his vomiting, and can discuss treatment options with you. I would take Rascal into an ER vet now, or find a vet on call to see him right away.
