Senior cat vomiting, not eating or drinking. Is it an emergency?

Updated on September 23rd, 2025

Pet's info: Cat | Cornish Rex | Female | spayed | 15 years and 3 months old | 5 lbs

I have a 15 yr old female Cornish Rex - she's been vomiting up clear semi-thick fluid / white foam for two days. She shows no interest in food, and some interest in water but won't drink. Her left eye has been watery (clear discarge) as well. She's alert, but not her normal very affectionate and loud self. I'm wondering if it's ok to wait until Monday to take her to her normal vet, or if I should go to the emergency vet. Thanks for your help!

As your cat has not been eating for a few days now as well as not drinking, this is an emergency. Cats can get liver disease from not eating for more than 2 days and not drinking will make them dehydrated and feel even worse and less inclined to drink and eat. Vomiting bile can be a sign of chronic or acute pancreatitis. There are some diseases that will have to be ruled out (can be done easily with a blood test), such as kidney disease and hyperthyroidism and dental problems. I think taking her to an emergency clinic is definitely warranted.

This is a medical emergency, and Zass needs to see a vet now. It's very serious when a cat doesn't eat for longer than 72 hours, as they develop a fatty liver which is fatal without treatment. He could have a severe GI illness, diabetes, kidney disease, liver failure, or even cancer causing his symptoms. He needs veterinary care now, please take him into one.

Thanks for using Petco Pet Education Center, formerly Petcoach! Vomiting and diarrhea can occur secondary to conditions such as inflammatory bowel disease, dietary indiscretion, parasites, among other possibilities. This could certainly be due to her hyperthyroidism or even due to the medications that she is currently on for it. I recommend that you have Gabriella evaluated by your veterinarian for further assessment and treatment. At the very least they can start her on medications to make her feel better and check her hydration status. In the meantime, keep water available at all times to try to prevent dehydration. Good luck and have a good day!

My 9-year-old cat has been vomiting for 5 days. Is it an emergency?

This is very concerning. Your cat may be suffering from pancreatitis, hyperthyroidism or severe gastritis or an intestinal blockage, By now this is an emergency and you will need to take your cat to a vet right away. Do not wait until the weekend or after , as your cat may even get sicker considering no food is being held. This can cause hyerlipidemia in addition to her illness and is life threatening. Please take Frankie in to a vet now,

My cat is vomiting bile, not eating, and lethargic. Is it a vet emergency?

It's really difficult to know for sure without being able to examine her. Given that she hasn't eaten for two days and is lethargic and vomiting, I have to recommend that she be seen by a vet as soon as possible. This could indicate a severe disease, or toxin ingestion. In both cases, her condition can diminish rapidly if not treated soon enough. If you have further questions or need further clarification, then you may consider having an online consult with one of our vets on Petco Pet Education Center, formerly Petcoach. This way, you can send unlimited pictures and have a text conversation with a vet. I hope that helps and Nibbler gets better soon.

My cat keeps vomiting, fussy, won't drink. When to see emergency vet?

I'm sorry to hear that Eggy has been vomiting and seeming fussy. In a young cat with sudden vomiting, fussy/abnormal behavior and decreased drinking, she may have a foreign body intestinal obstruction, virus, parasites, pancreatitis, or inflammatory bowel disease leading to her issues. Since she is not drinking well and continuing to vomit, it is likely that she has become dehydrated, so now is the time to take her to the emergency vet. The vet will examine her, perform any necessary diagnostic testing (likely including blood tests and x-rays), and then determine the best course of treatment. I hope this helps and that Eggy feels better soon!

My elderly cat with kidney disease vomited after medication. Is it an emergency?

It is important to note that elderly feline patients with chronic renal disease are much more likely to dehydrate than your average kitty. Some thing you will want to check for at home for evidence of dehydration is the moistness on the gum line as well as the pink / paleness, the skin turgor (the skin should return to the body when you pull on it). Dehydrated cats will also usually appear weak, lethargic and unwilling to perform some normal activities. Without having your cat in front of me, I would say that an actively vomiting cat with chronic renal disease should be seen tonight for sure IF the vomiting continues even once more. If you decide to hold off on going for now, that may be OK. You can consider trying to give something for the vomiting like pepsid or prilosec, though unfortunately I am unable to offer doses. Hope this makes sense. If you are having any doubts are all about your kitty's well being just bite the bullet and have him seen .

Why is my senior cat not eating, drinking, vomiting, and constipated?

I'm so sorry you're dealing with this. It sounds like your kitty is very ill. I would recommend taking him to an emergency clinic (or his regular clinic tomorrow if an emergency clinic is not possible) for an exam and labwork. This could be something treatable (or at least manageable, if not curable) or it may not be. I would be worried about kidney disease, thyroid disease, diabetes, cancer, and liver disease - it could definitely be other things too, but these are at the top of my list. Good luck with your kitty. Let me know if this was helpful advice or setup a consultation if you need further help.

My cat is vomiting, not eating, and lethargic. Is it an emergency?

Poor Moe! From what you're describing here, I'm afraid he sounds quite sick. Vomiting, not eating, and acting lethargic are always very concerning symptoms, especially since he's been sick for 2-3 days now and seems to be getting worse. Unfortunately, these are very vague symptoms that could be caused by almost any kind of illness, so it's hard to say what might be wrong without being able to examine him and run some tests. I do think that this sounds like a serious, potentially life-threatening problem that shouldn't wait until tomorrow, so I would recommend taking him to an emergency clinic today to be seen. If you're not sure where to go, try calling your regular vet's office - their voicemail message should have contact information for your nearest ER or an on-call doctor for emergencies.

My cat threw up, now lethargic, not eating. Is it an emergency?

This is a medical emergency, and you cannot do anything at home for Kitty. He has to see a vet now. Please take him into an ER vet clinic; if there isn't one in your area, there will be a vet on call for emergencies. The information to reach that vet is found on a clinic's answering machine or website.
