These prices come from bills that owners shared with us for this. We never publish names or addresses, we check each bill for duplicates and reading mistakes, and we compare the same charge with the same charge. “Most bills” means the middle half: a quarter were lower and a quarter were higher.
We publish what pet owners actually paid at the vet, from real bills they share with us. We are not a clinic and we don’t sell treatment; our job is to make vet prices clear before you get the bill. How we check the bills
Most bills in our data are an exam with medication and fluids, or that plus tests. A hospital stay is the expensive case.
Have these prices with you when you call a vet or check the bill afterwards.
A visit with medication only runs $120–$350. With tests it is $350–$750, and with a hospital stay $900–$2,000.

Free · your details stay private · no obligationVomiting and diarrhea treatment is covered as an illness under comprehensive pet insurance at 70–90% after deductible — it is one of the most frequently claimed conditions industry-wide. Exam, anti-nausea medication, fluids, diagnostics, and hospitalization are all eligible. Accident-only plans do not cover GI illness unless a swallowed object caused it. Chronic GI conditions diagnosed before enrollment are excluded as pre-existing.

Based on 44 real invoices, a vet visit for cat vomiting or diarrhea typically costs $225–$975. A straightforward visit with an exam and an anti-nausea injection runs about $120–$300 at a regular vet. Visits that add lab work and X-rays land in the $350–$750 range. Cases that need IV fluids and a hospital stay push past $900–$1,500, and emergency hospitals charge 2–3x more across the board.
Based on our invoice data, the most common line items are: exam fee ($50–$100 regular, $100–$250 emergency), an anti-nausea injection like Cerenia/maropitant ($25–$55), subcutaneous or IV fluids ($40–$350 depending on route), an anti-diarrheal or probiotic ($15–$45), a bland prescription diet ($20–$55), a fecal test ($25–$60), and — when the vet rules out an underlying cause — blood work ($100–$275) and abdominal X-rays ($150–$400).
A Cerenia (maropitant) injection for a cat typically costs $25–$55. Take-home Cerenia tablets run $2–$4 per tablet, or roughly $15–$45 for a short course. It is consistently one of the most common line items on cat vomiting invoices in our data.
Diagnostics are the biggest cost fork. Blood work (CBC + chemistry panel) adds $100–$275. Abdominal X-rays add $150–$400 for a 2–3 view study. An abdominal ultrasound, when the vet needs a closer look, adds $300–$600. A visit that stays symptomatic-treatment-only usually lands under $350; a full diagnostic workup pushes the bill toward $600–$1,000+.
Emergency-hospital treatment for cat vomiting or diarrhea typically costs $500–$1,500+, vs $120–$450 at a regular vet for comparable care. The ER exam alone is $100–$250. If the cat is dehydrated and stays on IV fluids with monitoring, expect $900–$2,000. Our invoice data for cats is consistent with that spread.
Yes — GI upset is one of the most common illness claims and is covered under comprehensive plans at 70–90% reimbursement after deductible. Exam, medications, fluids, lab work, imaging, and hospitalization are all eligible. A $500 GI visit at 80% reimbursement returns $400. Accident-only plans do not cover GI illness unless a swallowed object caused it, and chronic GI conditions diagnosed before enrollment are excluded as pre-existing.
Three forks drive the range in our 44 invoices: symptomatic treatment vs full workup (an injection-and-go visit is $120–$300; adding labs and imaging is $350–$750+), outpatient vs hospitalization (IV fluids with an overnight stay adds $500–$1,500), and regular vet vs emergency hospital (a 2–3x multiplier on everything). Geography adds the usual 20–30% urban premium.
