Endoscopy in a cat bills 1 lump sum that hides 5 parts, and the lump runs $900 to $1,800 for upper GI work in the US, 700 to 1,400 GBP in the UK, and 2,500 to 6,000 CNY in China. The 5 parts are pre-anesthetic bloodwork, anesthesia, the scope time itself, biopsies, and pathology. A colonoscopy lands at $1,000 to $2,000, and rhinoscopy or bronchoscopy at $1,200 to $2,400, because each needs a different instrument and a different amount of table time.
3 procedure types and 3 price columns
| Type | Typical use | US (USD) | UK (GBP) | China (CNY) |
|---|---|---|---|---|
| Upper GI: gastroscopy, duodenoscopy | Vomiting over 2-3 weeks, foreign body, stomach biopsy | 900-1,800 | 700-1,400 | 2,500-6,000 |
| Lower GI: colonoscopy to the ileocolic valve | Diarrhea with blood or mucus, colitis, 1-2 enemas first | 1,000-2,000 | 780-1,600 | 2,800-7,000 |
| Airway: rhinoscopy, bronchoscopy | Chronic sneezing, 1-sided nasal discharge, cough | 1,200-2,400 | 950-1,900 | 3,200-8,000 |
| Biopsy add-on | 150-350 per site, 3-8 sites typical | 450-2,800 | 350-2,200 | 900-6,000 |
| Pathology add-on | 100-250 per sample, 2-5 working days | 100-1,250 | 80-1,000 | 200-2,000 |
The add-on rows explain why 2 estimates for the same gastroscopy can differ by 2,000. A quote of 900 with no biopsy answers 1 question, whether the stomach looks inflamed. A quote of 1,800 with 6 biopsies and pathology answers which disease it is, and only the second one changes treatment.
Equipment: the number that decides if the clinic can scope a cat at all
A cat's esophagus is 8 to 10 mm across when relaxed, and the duodenum is 6 to 8 mm. A flexible scope with a 9 to 11 mm outer diameter, the size used in dogs, will not pass. Feline work needs a 5 to 7.9 mm scope with a 1.8 to 2.8 mm working channel, and a clinic that lacks one either refers the case or quotes a rigid scope, which limits the exam to the esophagus and stomach.
That is why the equipment line is 300 to 700 on its own in many US quotes: the scope is a 15,000 to 40,000 instrument that has to be cleaned and leak-tested between cases, and a flexible scope's channels degrade after a few hundred procedures. A hospital doing 3 scopes a week amortizes it differently from one doing 1 a month.
Anesthesia and table time
Every feline endoscopy is done under general anesthesia with an endotracheal tube taped to the side of the mouth, because the scope occupies the airway. Expect 30 to 60 minutes of anesthesia: 15 to 30 for a gastroscopy, 20 to 40 for a colonoscopy, 15 to 25 for a rhinoscopy, 20 to 35 for a bronchoscopy. Billing follows the same pattern as dental work, a base for the first 30 minutes and 40 to 90 for each extra 15-minute block.
Fasting is 8 to 12 hours for upper GI work, and water is usually withheld for 2 to 4 hours. A colonoscopy needs 1 to 2 enemas in the 2 to 6 hours before, plus a 24 to 48 hour low-residue diet; a colon that still holds stool can turn a 1,000 procedure into a repeat at full price.
Biopsy and pathology: the 2 lines that produce a diagnosis
Looking is not diagnosing. A stomach that appears normal on the screen can still be inflamed at the cellular level, and the reverse is also true, so most internists take 3 to 8 pinch biopsies from set locations: 2 to 3 from the stomach body, 2 from the antrum, 2 to 3 from the duodenum. Each site adds 150 to 350, and each sample sent for histopathology adds 100 to 250 with a 2 to 5 working day turnaround.
One practical point: biopsies taken with a 1.8 mm channel forceps are small, and a pathologist reading 2 mm fragments can call mild inflammation but not much more. Where the case matters, ask how many sites and whether the samples go to a lab that reads feline GI tissue regularly.
Foreign body retrieval: what endoscopy replaces
A linear foreign body or a gastric foreign body removed through the scope avoids a laparotomy at 1,500 to 3,500, so the 900 to 1,800 scope is the cheaper operation when the object is reachable. Retrieval adds 200 to 500 to the scope fee for the extra 20 to 40 minutes and the retrieval tool.
The limit is position. Objects past the duodenal flexure, or a linear material anchored under the tongue and sawing at the intestine, need surgery, and a scope that pushes a sharp object further down the gut can turn a 1,800 bill into a 3,500 one with 2 days of hospitalization at 180 to 400 a night.
Why the same scope swings 1.5 to 3 times
Hospital tier is the main driver: a general practice with a 5.5 mm scope to a referral internal medicine service is the 1.5 to 3 times gap, and the referral fee buys an internist's reading of the images, fluoroscopy for a stricture, and same-day pathology pickup. City adds 10 to 20% at the top end. Timing adds 150 to 400 for an after-hours case.
A quote 40% below the local band usually removes biopsy or pathology. Those 2 lines are 550 to 3,000 of the total, and removing them leaves a procedure that produces pictures but not a diagnosis, which means the 900 was spent and the question is still open.
When the scope is the wrong test
Ultrasound at 250 to 450 comes first for vomiting, because it finds a mass, an intussusception, or free fluid that no scope will see, and it costs a third of the procedure. Bloodwork at 80 to 180 comes first for any cat being anesthetized. A suspected perforation, a cat with a 3-day history of not eating, or a bowel loop that is dilated on film all go to surgery rather than to a scope.
4 things to confirm before booking
- Ask the outer diameter of the scope in mm; anything over 8 mm is a dog scope and will not pass a feline duodenum.
- Ask how many biopsy sites are included and whether pathology is inside the quoted total or billed after.
- Ask what the prep is, in hours of fasting and number of enemas, and who administers it.
- Ask if the hospital keeps the images; a second opinion at 150 to 300 needs the recording, not just a report.
The visit that leads to a scope is priced separately, and a 1 to 2 week workup before referral usually runs 2 to 4 visits, laid out in visit frequency and per-visit cost. Because a scope is rarely an emergency, the balance is often settled over time: payment plans compared covers the 0% in-house version. For a number built on your own case, the cost calculator takes procedure type and city.

Frequently asked
Why does a gastroscopy quote run from 900 to 1,800?
The procedure is the same; the package is not. At 900 you get the scope time and a look, with no biopsy and no pathology, which answers whether the stomach looks inflamed. At 1,800 you get 3 to 8 biopsy sites at 150 to 350 each plus histopathology at 100 to 250 per sample, and only that version names the disease and changes the treatment plan.
Can a cat be scoped without general anesthesia?
No. The scope occupies the airway, so an endotracheal tube is taped to the side of the mouth and the cat is kept under for 15 to 40 minutes depending on the procedure. Sedation alone does not control swallowing or protect the airway, and a moving cat risks a perforation that costs far more than the anesthesia line of 250 to 500.
Is endoscopy cheaper than surgery for a swallowed object?
Usually, when the object is reachable. Retrieval adds 200 to 500 to a 900 to 1,800 scope fee, against 1,500 to 3,500 for a laparotomy plus 180 to 400 per night of hospitalization. Objects past the duodenal flexure, or linear material anchored under the tongue, still need surgery, so the position of the object decides which bill you get.
