How Much Will Cat Intestinal Blockage Surgery Cost You?

Cats swallow things they shouldn’t. It happens. And if there’s one foreign object that really frightens veterinarians, it’s string. According to published 2026 figures, the cost of removing a blockage in a cat ranges from about $500 to $12,000. Here, we take a close look at the numbers, explain why they differ, and offer suggestions on what you can do if the estimate you receive is more than you can afford.

What to do if you can't afford treatment

Repeated vomiting, refusing food, hiding, straining to have a bowel movement without producing anything, belly pain, or a string visible in the mouth or protruding from the anus are all signs that your cat needs to be seen today, not tomorrow. A complete intestinal blockage will not resolve on its own and requires prompt veterinary treatment. In a 2025 study of 52 cats, those that survived a blockage underwent surgery an average of 67 hours after symptoms began, compared with 96 hours for those that did not survive.

Never pull on a string you can see. If it’s anchored around the base of the tongue or in the stomach, pulling on it can seriously damage the intestines. Don’t cut it or pull it. Take your cat to a veterinarian right away.

A blockage, or obstruction, occurs when something becomes lodged in the stomach or intestine, preventing food and fluid from passing through normally. Veterinarians generally divide these blockages into two types. In cats, the distinction is especially important because it can affect the type of surgery needed, the risks involved, and the cost of treatment.

Discrete objects

A hair tie, bottle cap, piece of a toy, or bone fragment. A single object becomes lodged in one place, preventing food and fluid from passing through. The intestine can swell behind the blockage, and blood flow to the affected area may become compromised.

Linear foreign bodies

String, thread, tinsel, ribbon, or dental floss. One end becomes caught, often around the base of the tongue or in the stomach, while the intestine continues trying to move the rest along. Instead, the intestine can bunch up along the string like a curtain on a rail.

Linear foreign bodies are particularly common in cats. In one recent surgical series, 18 of 56 cases involved linear objects; in a separate 2025 series, they accounted for 40.5% of cases. Together, these studies suggest that string and similar materials account for a substantial proportion of intestinal blockages in cats.

A solid object generally stays in one place. String behaves differently. Peristalsis, which is the wave-like movement that normally pushes food through the digestive tract, continues pulling on the free end while the anchored end stays put. As a result, the intestine can bunch up along the string, putting increasing pressure on the intestinal wall and potentially causing a tear or perforation. This is why the Merck Veterinary Manual warns never to pull on a linear foreign body visible in a cat’s mouth: if it is anchored farther down, pulling can damage the intestine.

The published outcome data reflects the added complexity. In a study of 56 cats treated at a university hospital, surgical-site infections occurred in 43% of cats with linear foreign bodies, compared with 4% of those with discrete objects. Surgery also took longer (a median of 73.5 minutes versus 51 minutes) and cats with linear foreign bodies received intravenous fluids for an average of 55.7 hours after surgery, compared with 30.2 hours for cats with discrete objects. More complicated surgery and a longer hospital stay can also mean a higher veterinary bill.

A cat that swallowed string yesterday and seems fine today may still have an obstruction. Signs can take a day or two to appear, giving the string time to cause damage before symptoms become obvious. If you saw your cat swallow string, it is worth contacting your veterinarian even if your cat seems well.

And if you can see string in your cat’s mouth or protruding from the anus, leave it alone. Do not cut or pull it. Take your cat to a veterinarian promptly.

Sometimes. It is a fair question to ask, especially because avoiding surgery can reduce the cost of treatment by thousands of dollars. Whether that’s possible depends on what your cat swallowed, where it is, how long it has been there, and your cat’s condition. Depending on those factors, your veterinarian may recommend monitoring the object to see if it passes, removing it with an endoscope, or inducing vomiting.

Watch and wait

This is only an option for a cat that is stable. The Merck Veterinary Manual describes monitoring an object with repeat X-rays, but there are limits: if the object hasn’t passed within 36 to 48 hours, is not moving between X-rays, or your cat’s condition worsens, surgery may be necessary.

Endoscopy

If the object is still in the stomach, a veterinarian may be able to retrieve it using a camera and specialized instruments passed through the mouth, avoiding an abdominal incision. Merck notes that endoscopy is generally limited to objects in the stomach because the scope cannot reach far into the intestine. It is not appropriate when a linear foreign body, such as string, is suspected.

Inducing vomiting

If your cat swallowed the object very recently, a veterinarian may be able to induce vomiting before it travels farther through the digestive tract. PetMD notes that the medications used to induce vomiting in cats are not always reliable, however, making this a more limited option in cats than in dogs.

Once an object has moved beyond the stomach, the intestine is fully blocked, or a linear foreign body is suspected, surgery may be necessary. Delaying recommended surgery in the hope of avoiding the cost can allow intestinal damage to progress, potentially turning a simpler procedure into one that requires removal of a damaged section of intestine. In the 2025 series discussed earlier, longer delays before surgery were associated with poorer outcomes.

Published survival figures for cats look inconsistent until you notice what separates them, which is the time lapse between the blockage and the surgery,and how sick it already was on arrival.

These are three different populations, so they are shown separately rather than combined into one number. The pattern across all three is the same: cats that reach surgery before significant intestinal damage occurs tend to do very well, which is why getting treatment promptly can make such a difference.

Merck notes that breakdown of the intestinal repair most often happens three to five days after the operation. Call the hospital immediately if your cat stops eating, appears to be in pain, vomits, or experiences discharge from the incision. Do not wait for the follow-up appointment.

Immediately after surgery, your cat will typically receive intravenous fluids, pain relief, and close monitoring while the digestive system starts functioning normally again. Cats treated for a string blockage may need a longer hospital stay. In the 56-cat study, intravenous fluids were given for an average of 55.7 hours after surgery for a linear foreign body, compared with 30.2 hours for a discrete object.

Once your cat is home, the first few days require particularly close attention because this is when complications such as leakage from the intestinal repair can occur. Follow your veterinarian’s feeding instructions, which may include small, frequent meals, and keep a close eye on both the incision and your cat’s appetite.

Activity will also need to be restricted while the incision heals. For a cat, that means preventing running and jumping and, in some cases, keeping them confined to a single room. PetMD puts typical recovery at around 10 to 14 days, with a follow-up visit to check the incision.

Five sources publish costs for intestinal blockage surgery in cats, and the figures vary widely. Because each source calculates costs differently, we’ve shown them side by side rather than averaging them.

Why the sources differ so vastly

The wide variation in published costs doesn’t necessarily mean that any of the estimates are wrong. They may simply be measuring different things. Four factors help explain the differences:

Where the cat is treated

A scheduled procedure at a general veterinary practice can cost much less than treatment at an emergency or specialty hospital. Most published estimates don’t specify the type of facility.

How complicated the surgery is

Removing an object through a small incision in the intestine is generally simpler than removing a damaged section of intestine and rejoining the healthy ends. The cost depends on what imaging shows, and sometimes on what the surgeon finds during the operation.

What the estimate includes

Some estimates cover surgery alone. Others may include the examination, X-rays or ultrasound, bloodwork, anesthesia, hospitalization, and medications to take home. That makes direct comparisons difficult.

String or not

A string or other linear foreign body can require a longer, more complicated procedure and a longer hospital stay than a discrete object. Most published cost estimates don’t distinguish between the two.

These figures are planning estimates, not quotes. The number that matters for your cat is the estimate from the hospital providing treatment, and it’s important to ask what that estimate includes.

If the cost of surgery is more than you can manage, there may still be ways to help cover the bill. Most families end up combining two or three options rather than finding one that covers everything, so start with whichever can provide help fastest.

• Talk to the hospital first. Ask whether they accept partial payment or offer an in-house payment plan. It’s best to have this conversation when your cat is admitted rather than waiting until discharge, so you know what options are available from the start.

• Ask what their estimate includes. An initial estimate may account for the possibility of more complicated surgery. Once imaging is complete, ask whether the estimate can be narrowed and whether it assumes that part of the intestine will need to be removed.

• Consider veterinary financing. CareCredit is accepted by many veterinary practices in the U.S., and you may be able to get a decision quickly. If you use a promotional financing offer, read the terms carefully. With deferred-interest promotions, failing to pay the full promotional balance by the deadline can result in interest being charged from the original purchase date.

• Look into charitable grants. Animal welfare organizations and some breed-specific groups offer financial assistance for veterinary care. Eligibility requirements and processing times vary, however, so these may be more useful as one part of your plan than as the only source of funding for urgent surgery.

• Try veterinary crowdfunding. Waggle is a nonprofit crowdfunding platform dedicated to veterinary care. You create a campaign based on your veterinarian’s treatment estimate, and once Waggle has verified and published it, you can share it with friends, family, and Waggle’s community of animal lovers. Funds raised are sent directly to the veterinary provider to help cover your cat’s care.
