My cat won't eat much for 3 days and vomited. When to call vet?

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.

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.

This is very concerning and very abnormal. Vomiting in cats can be caused by primary issues with the gastrointestinal tract, dysfunction of the organs, infection, intolerance to a diet, etc. Either way, this is very concerning and KitKat should be seen by a veterinarian ASAP for examination and potential diagnostics.

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,

If this has been going on for more than a few days it might be better to see an emergency veterinarian today, however if the symptoms are more recent you may be able to wait. If Greta's gums seem pale or she is having trouble breathing, or if she has a history of other medical problems it would also be better to have her seen today. Otherwise I think you can probably wait until tomorrow. Ultimately these symptoms are somewhat vague and can be a sign of a number of problems so you should go with your gut.

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!

If you don't think she has eaten anything at all in three days, she needs to be seen by a vet right away. Cats have to eat or else suffer liver damage in just a few days. If you haven't seen her eat but she is still using the litterbox and producing stool, then she's probably been eating something but it's still a good idea to get her seen as soon as possible.
