Cat Vomiting, Not Eating, and Hunched in Pain? Signs of Pancreatitis
🚨 Check first
If your cat vomits yellow liquid or foam repeatedly, refuses even favorite treats and has not eaten for over a day, or crouches hunched over to protect their abdomen and stays still (sometimes with diarrhea or fever), it may be acute or chronic pancreatitis, not just an upset stomach. Leaving this untreated can lead to hepatic lipidosis or multiorgan failure, so see a vet promptly.
📌 The answer in 3 seconds
- Pancreatitis occurs when powerful digestive enzymes leak from the pancreas and begin digesting the organ itself. It is very common in middle-aged and senior cats, and often occurs alongside inflammatory bowel disease (IBD) and cholangiohepatitis (known as triaditis).
- Unlike in dogs, feline pancreatitis often presents with subtle signs—there may be little vomiting, just a gradual loss of appetite and energy accompanied by steady weight loss. It is also hard to find with routine blood tests alone.
- Diagnosis involves a feline pancreas-specific lipase (fPL) blood test and abdominal ultrasound at the vet, focusing on recovery through fluids, anti-nausea medication, pain relief, and early nutrition.
📊 Flowchart
- Step 1If nausea (lip-smacking, drooling) + complete loss of appetite + hunched, motionless posture occur together, do not wait at home—see a vet the same day.
- Step 2Ask the vet about running pancreatitis tests (fPL) and an ultrasound alongside routine blood work, and receive subcutaneous or IV fluids, anti-nausea meds, and pain relief.
- Step 3Unlike in dogs, fasting a cat with pancreatitis is dangerous and can trigger hepatic lipidosis. Once anti-nausea medication takes effect, start offering small amounts of easily digestible wet food or liquid recovery food right away (or feed via syringe if they won't eat on their own).
⭕ Step-by-step fix
Step 1 · What you can do at home right now
If nausea (lip-smacking, drooling) + complete loss of appetite + hunched, motionless posture occur together, do not wait at home—see a vet the same day.
Step 2
Ask the vet about running pancreatitis tests (fPL) and an ultrasound alongside routine blood work, and receive subcutaneous or IV fluids, anti-nausea meds, and pain relief.
Step 3
Unlike in dogs, fasting a cat with pancreatitis is dangerous and can trigger hepatic lipidosis. Once anti-nausea medication takes effect, start offering small amounts of easily digestible wet food or liquid recovery food right away (or feed via syringe if they won't eat on their own).
❌ Never do this
- Fasting your cat for 2–3 days out of a belief that 'fasting rests the stomach when vomiting' (in feline pancreatitis, stopping nausea and providing nutrition as early as possible speeds up recovery).
- Feeding cats human fatty foods like fried chicken, bacon, or heavy cream.
