My cat ran out a few days ago and came back today, but as soon as it returned it kept foaming at the mouth and vomited for almost two hours, then threw up something unidentifiable, and after that started foaming again. What should I do?
Frequent vomiting in cats can be caused by many things, including indigestion, gastroenteritis, liver disease, kidney disease, intestinal obstruction or infectious disease, and food or drug poisoning. Based on your description, the cat vomited continuously after coming home from outside, so it may have accidentally eaten a poison outdoors causing toxicity, or it may have eaten unclean food leading to gastroenteritis or gastrointestinal blockage, or contracted an infectious disease causing frequent vomiting. If the cat vomits whatever it eats, it is recommended to withhold food and water promptly to avoid burdening the digestive tract, and take it to a veterinary hospital for examination as soon as possible. The veterinarian will give a corresponding treatment plan based on symptoms and test results; giving medication at home may worsen the condition. Also, keep the cat in a clean environment and prevent it from contacting harmful substances.
My cat is vomiting yellow fluid and won’t eat
Vomiting yellow fluid and not eating can be from infectious disease, foreign-body obstruction, hairballs, parasites, or acute gastroenteritis. First rule out infectious disease and do blood work at a vet, then treat the cause. Withhold food half a day to a day and watch; frequent vomiting risks dehydration — give fluids and an anti-vomiting injection. Self-medicating may worsen it; a vet visit is best.
It hasn’t eaten for three days and won’t even take force-feeding; I thought it was gastroenteritis and gave medicine but it vomited it up. On the fourth day the hospital confirmed feline panleukopenia (distemper), and it’s had IV fluids for four days. White blood cells went 4.7 to 3.8 to 5.1 to 7.9, FPV-AG now 38.18 ug/ml. It can eat now and energy is better — does it still need treatment, or can we stop and let it recover slowly?
Feline panleukopenia is usually dangerous, with a course of about 7–10 days; active treatment and monitoring are advised, and stopping medication should follow the vet's instructions — never stop on your own. Continue until energy, appetite, and stool are normal, then recheck WBC, SAA, and antigen; after they return to normal ranges, some antivirals and fluids can be tapered, but gut repair needs longer care.
What are the causes of a cat bleeding?
From the photo, the cat is bleeding and has diarrhea, but the bleeding site cannot be determined from the photo; it could be external or internal injury. If external, it may be cut by a sharp object and stressed into diarrhea — treat the wound and give probiotics. If diarrhea with blood, consider gastrointestinal bleeding, bacterial gastroenteritis, or intestinal laceration, and see a vet.
My cat vomited undigested kibble, then yellow fluid with white foam, now only white foam. What should I do?
Vomiting yellow fluid and white foam usually points to a digestive disease with many possible causes, so withhold food and water and see a vet for a confirmed diagnosis. Common causes include hairball gastritis, parasites, acute gastroenteritis, wrong food or poisoning, and panleukopenia.
My cat has loose stools; after defecating its rear swells slightly with watery discharge, but it is alert yet has reduced appetite
Loose stools with a swollen rear may stem from gastroenteritis, parasites or food allergy; have a vet diagnose the cause. If a visit is hard, clean the area with saline-soaked gauze. For ongoing diarrhea, give pet anti-diarrheal and anti-inflammatory medication, and apply ointment to the swollen anus avoiding licking.

What to Do When a Cat Keeps Vomiting from a Weak Stomach?
As known, a cat's stomach is more fragile than other animals, so vomiting is common. But if it keeps vomiting, the owner must treat it. What to do when a cat with a weak stomach keeps vomiting? Let's see with our veterinarian.
My cat vomits long white worms; I looked it up and it seems parasitic — how to treat it? It usually won’t eat or drink, foams, and occasionally passes worms.
Long white worms are likely roundworms, common gut parasites spread via feces or food. Treat with a suitable dewormer such as pyrantel, praziquantel, or albendazole per the vet. Since the cat won't eat and foams, it may have secondary gastroenteritis needing fluids, anti-emetics, and gut repair. Deworm every 3 months and clean the environment to prevent reinfection.
What Happens If a Cat Eats Anti-Inflammatory Medicine?
Anti-inflammatory medicine can control internal inflammation and prevent infection in cats with skin, respiratory, or urinary infections, but only pet-specific drugs at the correct dose should be used to avoid indigestion, allergy, or liver damage.
