My cat keeps throwing up yellow foamy bile. When is it an emergency?

I don't think this require an emergency visit but i would definitely recommend making a sooner apointment for you vet, preferably before the weekend as this sound like a gastrointestinal condition that will require treatment, possibly a course of antibiotics and a change of food.

Hello, sorry to hear about Cheeto. I would watch him for continued episodes of vomiting or if he develops any lethargy, decreased appetite or diarrhea. Things we worry about with sudden onset or persistent vomiting in cats include dietary indiscretions, inflammatory bowel disease (IBD), ingestion of foreign material, obstruction or a mass which is probably the least likely in a young cat. If his vomiting persists or gets worse overnight, or if he develops any other signs then I would definitely bring him to an emergency clinic. You should not attempt to feed him today and then offer boiled chicken and rice tomorrow in the morning. Hope this helps and best of luck.

This does appear like blood, but I would first want to know if he/she ate anything that was red colored. If she/he did eat something red colored within the past three hours, then I'd assume this is causing this appearance. If not, then it's likely blood, which indicates an esophageal or gastric ulcer. Bleeding from these locations can be dangerous, because they can lose a significant amount of blood in the stomach and intestines. For this reason, we consider this an emergency and recommend a visit to the vet as soon as possible for an accurate diagnosis and treatment. It's not possible to say exactly what is causing this, as there are a few different possibilities. One possibility is that your cat ate something they were not supposed to like medication, a chemical (i.e. antifreeze), or a plant (i.e. lilies). Vomiting is often the first signs of an exposure to a toxin, so I recommend checking if it's possible for your cat to have eaten anything other than the normal diet. Vomiting and nausea can also be due to an infectious disease, organ failure, or imbalance in the blood. In order to narrow down the possibilities, you would have to take your cat to the vet for an evaluation. 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 your cat gets better soon.

If Tom only vomited one time I would not be that concerned but multiple bouts of vomiting in a short period of time is very concerning. He really needs to be examined by a vet as soon as possible. Vomiting is a very vague symptom and does not point to any one disease process or illness. He needs to be examined and possibly some testing will be needed.

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,

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.

Poor guy. If he continues to vomit or is also really lethargic, has pale gums or is breathing abnormally, then that indicates he is highly unstable and needs to go to an ER vet. However, if he is still alert, active and mentally sound, he should be ok to try a bland diet of tuna and white rice to hopefully settle his stomach. He may have an infection however so have him seen by a vet first thing in the morning if he continues to have these symptoms. I hope your kitty Elliot feels better soon!
