What are the common causes of pancreatitis in cats?

Pancreatitis in cats is often linked to dietary issues, metabolic diseases, or biliary abnormalities, though the exact cause is not always clear. Your vet will assess the history and perform appropriate tests to evaluate the cause.

How does the vet diagnose pancreatitis in cats?

Diagnosis typically combines blood tests, a feline-specific pancreatic enzyme assay (fPLI), and abdominal ultrasound. Follow-up tests or further imaging may be arranged if needed — please ask your vet for details.

What is the treatment and prognosis for feline pancreatitis?

Treatment centres on fluid therapy and supportive care. Mild cases may be managed as outpatients, while severe cases require hospitalisation. Prognosis depends on disease severity and any complications — follow your vet's recommendations for monitoring.

How much do the tests and treatment usually cost?

Costs vary by clinic and region — ask your vet for an estimate before proceeding.

When to See a Vet

Seek immediate veterinary care (emergency)

•Persistent vomiting, inability to keep water down, or obvious weakness
•Sunken eyes, dry mouth, or clearly reduced skin elasticity
•Blood in vomit or stool, with a dark red or black color

Schedule a clinic visit as soon as possible (within 24-72 hours)

•Appetite is clearly reduced and lasts for more than 24 hours
•Frequent vomiting, with episodes clearly increased from usual
•Diarrhea or changes in stool consistency with reduced energy and activity

01What symptoms indicate something is wrong?

Pancreatitis often causes digestive discomfort and changes in alertness. Monitor your cat's eating habits, vomiting frequency, and activity level.

Lethargy and noticeably reduced activity
Decreased appetite or refusing to eat — see a vet if this lasts more than a day
Frequent or increased vomiting
Diarrhea or changes in stool consistency (loose stools or bloody stool)
Fever or abnormal body temperature — measure to confirm
Return for a check-up if weakness, excessive sleepiness, or unwillingness to move develops

Seek emergency care immediately if you notice the following symptoms:

⚠️ Persistent vomiting with inability to keep fluids down, or noticeable weakening
⚠️ Clear signs of dehydration such as sunken eyes and dry mouth
⚠️ Vomit or stool containing blood, appearing dark red or black

02What should you check at home? Key observations and when to go to the emergency clinic

Systematic at-home observation and records of symptoms, eating, and elimination help the vet assess your cat's condition quickly.

Note when changes in alertness and activity began and how they progressed
Measure and record daily food intake, number of meals, and type of food
Record the number of vomiting episodes, what was vomited (food, bile, or blood), and the times
Photograph or collect a stool sample and describe its colour and consistency
If possible, take your cat's temperature, record the reading and photograph any abnormal results
Seek veterinary attention promptly if symptoms worsen or warning signs appear

03How will the vet diagnose this? Common tests and examinations

At the clinic, the vet will use blood tests and imaging to assess pancreatic status and potential complications.

Complete blood count and biochemistry panel

assessing liver and kidney function and pancreas-related markers

Feline-specific pancreatic enzyme assay or immunoreactivity test (fPLI, depending on clinic equipment)

Urinalysis

helps identify dehydration or other systemic issues

Abdominal X-rays

to rule out foreign bodies, swelling, or other abdominal problems

Abdominal ultrasound

to evaluate pancreas size, structure, and surrounding inflammation

Cytology or tissue biopsy may be recommended in some cases to evaluate pathological changes

04How is it treated and managed after diagnosis? Medications, dietary changes, and home care

Pancreatitis is managed primarily with supportive care. Hospitalisation and follow-up frequency depend on disease severity; clinical and laboratory results are monitored closely.

Fluid therapy to correct dehydration and electrolyte imbalances — hospitalisation or outpatient IV fluids may be needed
Anti-nausea and pain relief medications based on the vet's assessment
Antibiotics may be considered if there is a risk of infection or complications
Diet adjusted to low-fat or easily digestible food; dietary plan to be reassessed at follow-up
Regular follow-up visits to monitor blood values and clinical signs
Referral to a specialist clinic is recommended for severe or complex cases

05What should you prepare before the vet visit? Key information to help the vet identify the cause

Write down when symptoms started and how the condition has progressed

Record the types and amounts of food your cat has eaten in the past 24–72 hours

Bring photos or videos of vomiting or bowel movements for reference

List all current medications, supplements, and known allergies

If possible, bring a recent stool sample or other specimens

Use a secure carrier and book an appointment in advance to reduce waiting time
