If your cat ate string, tinsel or ribbon, treat it as an emergency and call for help right now. Contact your own veterinarian, the nearest emergency animal hospital, or a 24/7 animal poison line: the ASPCA Animal Poison Control Center at 888-426-4435 or the Pet Poison Helpline at 855-764-7661. Do not pull on any string you can see, and do not try to make your cat vomit. Swallowed thread can saw through the intestines, so a professional needs to assess your cat quickly. Prompt care gives your cat the best chance of a full recovery.
This page explains why a swallowed strand is so serious, what to watch for, and the mistakes that turn a treatable problem into a fatal one. It is general information, not veterinary advice, and it is never a substitute for a hands-on exam.
Do This First If Your Cat Ate String
Speed and the right first move matter more than anything else here. Work through this short list, then get on the phone.
- Call a professional now. Phone your veterinarian or the nearest emergency clinic. If you cannot reach one, call the ASPCA Animal Poison Control Center at 888-426-4435 or the Pet Poison Helpline at 855-764-7661, both open 24 hours a day. Each hotline charges a per-incident consultation fee because they are staffed by veterinary experts and receive no government funding; say yes to it, because the guidance is worth it in an emergency.
- Do not pull the string. If you can see thread hanging from your cat's mouth or backside, leave it exactly where it is. Pulling can cut the gut from the inside.
- Do not make your cat vomit and do not give any food, oil, laxative or home remedy. Only a veterinarian can decide whether that is ever safe, and for a linear object it usually is not.
- Gather the facts the vet will ask for: roughly when it happened, what kind of string it was, how much is missing, and whether your cat has vomited or eaten since.
Staying calm helps your cat. With a swallowed string the danger is real but usually not instant, so you have time to get to help without panicking.
Why String Is So Dangerous: The Linear Foreign Body
Veterinarians have a specific name for a swallowed strand: a linear foreign body. According to VCA Animal Hospitals' published guidance, reviewed September 2026, one end of the string often catches and anchors in place, commonly around the base of the tongue or at the exit of the stomach, while the rest trails down the intestine.
From there the real harm begins. Every time the cat swallows, the anchored string tugs, and the intestine tries to creep along it. The Merck Veterinary Manual describes how a linear foreign body causes the bowel to gather, or plicate, bunching up like fabric on a drawstring. The taut thread then acts like a saw against the folded tissue and can slice through the intestinal wall from the inside, spilling gut contents into the abdomen. That is why a strand of thread, which sounds so harmless, is considered one of the most dangerous things a cat can swallow.
This is also why a linear foreign body is not simply an obstruction you can wait out. It keeps working, hour after hour, until it is removed.
Tinsel, Ribbon, Yarn and Elastic: Cats Cannot Resist Them
Cats are hunters, and a dangling, twitching strand looks exactly like prey. The backward-facing barbs on a cat's tongue make the problem worse: once a strand is in the mouth, those barbs push it toward the throat, so spitting it out is harder than swallowing it. Any thin, trailing item can become a linear foreign body, including sewing thread, dental floss, yarn, shoelaces, hair ties, elastic, fishing line, and the ribbon and tinsel that appear around the holidays.
Seasonal decorating is a high-risk window. Tinsel and curling ribbon are shiny and move in a draft, and gift wrap is often left in reach. The same festive shelves that hold treats often hold homemade salt dough ornaments and other decorative salt objects, which bring their own separate danger if a curious pet chews them. Keeping thread-like items and edible decorations out of reach is the simplest way to avoid an emergency vet visit.
Warning Signs to Watch For
If you did not see your cat swallow anything but you are worried, watch closely. The signs below are among those veterinary sources associate with a gastrointestinal foreign body; they are not a diagnosis, and only a vet can confirm what is happening inside your cat.
- Repeated vomiting or retching, or trying to vomit and bringing nothing up
- Refusing food, or eating far less than normal
- Lethargy, hiding, or a hunched, tucked-up posture
- Signs of belly pain, such as crying, tensing, or resisting when the abdomen is touched
- Straining in the litter box, diarrhea or constipation
- Drooling or pawing at the mouth
- String visible under the tongue, at the lips, or hanging from the rear
One sign deserves special mention. If a strand has wound tightly around the base of the tongue, the tongue can look swollen, dark or purple because circulation is cut off. That is a call-now situation. Do not try to unwind it yourself.
What You Should Never Do
Good intentions cause many of the worst outcomes here, so it is worth being blunt about the traps.
- Never pull a visible string. Whether it hangs from the mouth or the back end, pulling can drag the sawing edge against tissue and tear the gut. If it is caught, you cannot feel where or how tightly. Let the vet remove it under sedation.
- Never induce vomiting and never reach for a human medicine, oil or laxative to move it along. A strand that is anchored can do more damage on the way back up, and the wrong product can poison a cat outright.
- Never adopt a wait-and-see approach on the assumption it will simply pass in the stool. Some do, but many do not, and by the time outward signs appear, real damage may already be underway.
String is not the only ordinary household item that turns dangerous once a pet swallows it. Cooked bones and fat trimmings, for example, cause a different but equally serious kind of internal injury, which is a good reminder that the kitchen and the craft drawer both deserve caution around animals.
What the Vet Will Do
Handing this over to professionals is the whole point. A veterinarian will start with a physical exam, which often includes looking carefully under the tongue, since that is a classic anchor point that owners cannot check safely at home.
To see what is going on inside, the vet may recommend imaging such as x-rays, and sometimes an ultrasound or an endoscopy to view the digestive tract directly. Depending on where the string sits and how much damage it has caused, treatment ranges from careful monitoring in the hospital to surgery to remove the strand and repair the intestine. As a general rule described in veterinary references, the further the string has traveled and the longer it has been in place, the more complex the surgery and recovery tend to be, which is exactly why early care matters so much. Your veterinary team will explain the options and costs for your specific cat before anything is done.
Can a Swallowed String Pass on Its Own?
Sometimes a short, non-anchored strand does move through and come out in the litter box without harm. The trouble is that you cannot tell from the outside which case you have, and guessing wrong can be fatal. For that reason the answer is never to sit and hope. A veterinarian, using an exam and imaging, is the only one who can judge whether careful monitoring is safe for your particular cat or whether it needs to be removed. Toxicity and risk vary with the animal's size, age and overall health, and that judgment belongs to a professional who can examine your cat.
Preventing the Next String Emergency
Prevention is far easier than surgery. A few habits keep thread-like hazards out of a cat's reach:
- Store sewing kits, yarn, floss, hair ties, shoelaces and fishing line in closed containers or drawers.
- Cut and bin the plastic rings and drawstrings from packaging before a cat finds them.
- At the holidays, skip tinsel in a cat household, keep ribbon and gift wrap put away between uses, and secure the tree.
- Never let a cat play unsupervised with a wand toy that has a string; put it away after play.
- Watch the kitchen too, since the festive season brings other hazards like raw bread dough left out to rise, which is dangerous for pets for reasons all its own.
If you keep the emergency numbers somewhere easy to find, you will not lose precious minutes searching for them when it counts.
When to Call and Who to Call

Frequently Asked Questions
My cat ate string but seems totally fine. Do I still need to call?
Yes. A cat can look normal for hours while a linear foreign body is quietly causing harm inside, so a bright, playful cat is not proof it is safe. Call your vet or a poison line for advice specific to your cat.
Can I just pull the string out if I can see it?
No. Pulling a visible strand, from either the mouth or the rear, can drag its edge against the gut and tear it. Leave it in place and let a veterinarian remove it under sedation.
How long does string take to pass through a cat?
There is no safe number to rely on, because it depends on the type and length of string, where it lodges, and your cat's own anatomy. Rather than waiting for it to appear in the litter box, let a veterinarian decide whether monitoring is safe.
Is tinsel more dangerous than other string?
Tinsel is a classic linear foreign body and is especially tempting because it is shiny and moves, but any thin, trailing item carries the same risk. The danger is the shape and behavior of the strand, not the specific material.
What will it cost to treat?
Costs vary widely with what your cat needs, from a consultation and imaging to surgery. Your veterinary team will explain the options and expected costs for your cat before proceeding, so ask them directly.
