This page is not veterinary advice. It cannot examine your cat and it does not know what she swallowed. It exists to help you look properly, gather the few facts that matter, and decide when to call - and then to hand the decision to someone qualified to make it. If you are worried at all, phone your own vet, or an emergency vet if yours is closed, now.
Nothing here tells you to do anything to your cat. That is deliberate.
It is usually quiet when you notice. A leaf on the windowsill with a bite out of it. A blister pack on the floor with one bubble burst. A length of thread that was on the table and is now not on the table. And a cat sitting in the middle of it washing a paw, as though the room had always looked like this.
Cats rarely make a scene about what they have eaten the way a dog does, so owners usually find the evidence rather than the event. That gap - between the thing happening and you working out that it happened - is what this page is built around. You cannot go back and watch it. What you can do, in the next few minutes, is establish what you are actually dealing with, collect the handful of facts a vet will ask for before anything else, and make the call quickly and calmly rather than spending twenty minutes reading strangers arguing in a forum.
That is a job you can do well, and doing it well genuinely changes how useful the phone call is.
The only instruction on this page
Phone your own vet, or an emergency vet if yours is closed. Do it now, and read the rest while you wait for them to pick up. You are not wasting anyone’s time: working out whether this matters is exactly what that phone call is for, and every vet would far rather hear from you early about something harmless than late about something that was not.
Go straight there, without phoning first, if any of this is true: your cat is struggling to breathe or breathing with her mouth open; she has collapsed or cannot stand properly; she is having a fit; there is heavy bleeding; something is hanging from her mouth or from her back end; or your gut is telling you this is bad. Trust the gut. It is right far more often than a search result.
No number saved? Find an emergency vet and put it in your phone now. On a calmer day, write it on the printable fridge sheet as well, so it is on the wall and not only in a device that can be flat or locked.
If the cat in question is a new kitten, the first month has its own set of hazards and its own set of normals - lilies, string and cables at the top of the list. New Kitten: The First 30 Days covers proofing the house before the carrier opens, and what counts as normal in the first weeks.
When this is over, the prevention side is worth an hour: Pet-Proof Your Home: The Room-by-Room Audit walks the house at cat height, covering lilies, strands, worktops, balconies and every latched cupboard that should be latched.
Cats are the animals whose details owners are least able to produce under pressure - the weight, the last parasite product, whether she is indoor-only. Fix that on a calm evening with The Pet Emergency Folder, which lays out exactly what to record and gives you a printable pack to write it on.
A cat is not a small dog
Almost everything written about pets eating things they should not is written about dogs. Dogs are noisier, greedier and far more likely to be caught in the act, so they generate the stories, the search traffic and the advice. Reading that advice with a cat in the room is one of the quieter risks of a night like this, because cats differ in ways that matter.
They process many substances differently, so a thing that is a nuisance for a dog can be a serious problem for a cat, and the reverse is also true. They are small, so a quantity that reads as trivial in a paragraph written about a large dog is not trivial at all when the animal weighs a few kilograms. They groom, which gives anything that lands on the coat or the paws a second route into the cat even if she never went near it with her mouth - spilled liquids, dust, powder, pollen. And they hide discomfort, because in the wild a cat that looks unwell is a cat that looks catchable. The instinct that keeps a cat alive outdoors is the same instinct that makes her a poor witness to her own emergency.
So the ordinary reassurance signals are less reliable here. A cat sitting normally on the sofa is telling you very little. That is not a reason to panic; it is a reason not to use her behaviour as your evidence. Use what you found on the floor instead.
Step 1 - Put something between your cat and whatever it was
Before anything else, make it impossible for this to happen twice in the same hour. Cats that have found something interesting very often go back to it, and the second visit tends to be less exploratory than the first.
The simplest version of this is a door. Either your cat is on one side of it or the plant, the packet, the spill or the sewing basket is. You do not need to move her, catch her or hold her - closing a door does the job and avoids turning a calm cat into a frightened one. If there are other animals in the house, they need to be on the safe side of that door too; whatever tempted one of them will tempt the others, and a second patient is the last thing tonight needs.
This is housekeeping, not treatment. It is the one physical thing on this page, and it is done to the room, not to the cat.
Step 2 - Keep everything, including the mess
Whatever is left is the most useful thing in the house right now, and the instinct to tidy it away is strong and worth resisting.
- The packet, box, blister pack, bottle or wrapper - with the label, the ingredients and the strength still readable.
- The plant, or a cutting of it, or the pot with its little plastic tag still in the soil. A photograph works if the plant is enormous.
- What is left of the object: the rest of the string, the other half of the toy, the chewed cable.
- Any mess your cat has already made. It is unpleasant to keep and it can be genuinely informative, so bag it rather than mop it.
- A photograph of all of it on your phone, in case you have to leave in a hurry and the evidence does not come with you.
A vet can work with a photograph of a label. A vet cannot work with a memory of a green plant with pointy leaves. If you are not sure what the plant even is, our poison control directory and the list of plants that cause problems for pets can help you put a name to it while you are on hold.
Step 3 - The three facts, then everything only you know
Every conversation you are about to have starts with the same three questions, in the same order. Having the answers ready is the single biggest difference between a five-minute call and a twenty-minute one.
What, roughly how much, and when
What. Read it off the packet rather than from memory, including the full name and the strength if there is one. If it was a plant, get the name from the label or the checker rather than describing the leaves.
Roughly how much. Nobody expects precision. What helps is the honest range: how much was there before, how much is there now, and how much of the difference could plausibly have gone elsewhere. “There were eight and now there are five, but one may be under the sofa” is a genuinely useful answer. A confident guess is not.
When. Give a clock time, not an elapsed one. “Some time between half past nine, when I went upstairs, and quarter past ten, when I came down” is far more useful than “about an hour ago”, and it stays true while you sit in a waiting room. If you truly do not know, the honest answer is the last moment you are certain the thing was intact.
Then the things only you can tell them, which no page and no calculator can supply:
- Her weight, as an honest range if you have not weighed her recently, and roughly when it was last checked.
- Her age, and whether she is a kitten, an adult or an older cat.
- Anything she is already being treated for, and anything she is already given regularly - name it from the packet, not from memory.
- Whether she is pregnant or nursing, if that is possible.
- What is normal for this particular cat, so that anything you describe tonight has something to be measured against.
If you want this laid out as a fill-in card you can read down the phone, that is exactly what Before You Call the Vet is for - the two-minute preparation, written for precisely this moment.
Step 4 - Find out what you are dealing with, while you wait
Looking something up is not a substitute for the call. It is what makes the call better, and it gives your hands something to do in the ten minutes that would otherwise be spent staring at the cat.
- Pet poison control directory - the broadest of our tools, covering common household and food substances for both cats and dogs.
- Poison control directory and the poison control directory - for anything that came off a windowsill, a bouquet or a garden.
- Human painkillers - one of the most common and most serious calls involving cats, and one where a cat is not remotely comparable to a dog.
- Onion and garlic - including the versions hidden inside cooked food, stock and leftovers.
- The poison control directory and food search - if it came off a plate.
- Pet food recall checker - if what she ate was her own food and she became unwell afterwards.
- Pet emergency triage helper - if you are unsure how urgent any of this is.
A word about our own tools. A reassuring answer from any checker on this site is not a clearance. These tools work from typical figures and cannot see your cat, her age, her kidneys, her liver or what else she has eaten today. They exist to make you a better-informed caller - never to replace the caller. If a tool says one thing and your instinct says another, phone anyway.
Step 5 - Make the call, and make it a good one
Open with the sentence that gets you to the right person fastest, then read your facts in the order they were asked for.
“Hello - I have a cat who has eaten something and I need advice. She is [age], roughly [weight], and she is normally treated for [condition or nothing]. I think she ate [name off the packet] between [time] and [time]. There were [amount] and now there are [amount]. I have the packet in my hand. Right now she is [what you can see].”
Then let them ask. Write down what they tell you, and read it back before you hang up - at two in the morning you will not remember it, and a person who is frightened remembers instructions in the wrong order. Two questions are always worth asking: should I be coming in, and if so how soon, and what should make me call you back sooner than we agreed. The second one turns a vague “keep an eye on her” into something you can actually act on.
If you are going in, tell them you are coming and roughly when. A practice that knows a cat is on the way can have things ready. Arriving unannounced costs minutes at the door.
Lilies: the one that does not wait for symptoms
If there is a single thing that separates a cat emergency from a dog one, it is this. Lilies are extraordinarily dangerous to cats, and the danger does not behave the way people expect a poisoning to behave.
It is not only about eating a leaf. Every part of the plant is a problem, and so are the parts that never look like food: the petals, the stamens, the pollen that drops onto a shelf or brushes onto a coat as a cat walks past, and the water in the vase. A cat who grooms pollen off her own fur has taken it in as surely as one who chewed a leaf. Cats who have never shown the slightest interest in plants have been affected by a bouquet somebody brought as a gift.
The part that catches people out is the timing. A cat who has had contact with a lily can look completely well while the damage is being done. There is no early wobble, no obvious distress, nothing to react to - which is exactly why the internet advice to watch and see is so dangerous here. By the time a cat looks unwell, the situation is much harder to help. Do not wait for symptoms. Do not wait to see whether she seems fine. Phone now, tonight, and say the word “lily” early in the sentence - it changes how the call is handled.
Any known or even suspected contact counts: a nibbled leaf, a chewed petal, pollen on the fur, a drink from the vase, or simply finding a lily in the house with a cat and no way of knowing what happened while you were out. Suspicion is enough to justify the call. Being wrong costs you a phone call; being right and late costs a great deal more.
For which plants carry the name and which do not, we keep separate pages on lilies and cats and on the peace lily, which is a different plant with a different problem and is frequently confused with the true lilies. If you are unsure which you have, treat that uncertainty as a reason to call rather than a reason to relax.
String, thread, tinsel, ribbon and hair ties
The other classically feline emergency is not a poison at all. It is anything long and thin.
Cats are built to deal with long thin things by swallowing them. The backward-facing barbs on a cat’s tongue mean that once something stringy is in the mouth, spitting it out is genuinely difficult, and swallowing is the path of least resistance. It is not greed and it is not stupidity; it is anatomy. Sewing thread with a needle still attached, dental floss, tinsel, ribbon from a parcel, the elastic from a hair tie, the drawstring from a hood, the tail off a toy mouse - all of it belongs in the same category.
This category deserves its own paragraph because the usual reasoning fails on it. With most swallowed objects, owners tell themselves it is small and it will pass, and often that is true. With something long and thin, size is not the risk. The risk comes from one end staying put while the rest keeps travelling, and that is a mechanical problem inside an animal, not something that resolves itself with patience.
Two things follow from that, and both of them are things not to do. Do not decide to wait and see whether it appears, and if you can see any part of it - at the mouth, under the tongue or at the back end - do not pull it. Pulling is the specific action that turns this from a problem into a much worse one. Leave it exactly where it is, do not cut it, and say on the phone that you can see it. That single sentence will change the urgency of the answer you get.
The routes into trouble that are particular to cats
When you are trying to work out what she might have got into, it helps to know where cats actually get into things - which is not always where dogs do.
- The coat and the paws. Anything spilled, dripped, tracked through or settled as dust ends up in the cat when she grooms. A cat who walked across a wet floor has effectively tasted whatever was on it. This route means “she never went near it with her mouth” is not the reassurance it sounds like.
- Height. Cats reach the places that were considered safe: the top of the fridge, the back of a worktop, the shelf where the tablets live, the windowsill with the bouquet. Storage that defeats a dog is an amusement for a cat.
- Small containers. Handbags, washbags, bedside drawers and coat pockets left open by visitors are a recurring theme, and visitors do not know the house rules.
- Human medicine. A cat is small and processes many medicines quite differently, so this is a category where the ordinary intuition about quantity is simply wrong. Never assume a small amount is a small problem.
- Warm places. Engines, tumble dryers and airing cupboards are not swallowing hazards, but they belong on the same mental list of places a cat has been that nobody thought to check.
If you want to go through the house properly on a calmer day, our poison control directory walks room by room and links each hazard to the page that explains it.
Describing what you can see, without diagnosing it
On the phone you will be asked what she is doing. The useful answer is plain description - what you can actually see, in ordinary words, with a time attached. Leave the conclusions to them; a diagnosis offered by an owner tends to steer the conversation rather than inform it.
Useful things to describe, if they are there:
- Breathing - fast, slow, noisy, quiet, with the mouth open or closed, and whether the effort seems to be in the chest or the belly. Any open-mouth breathing in a cat is worth saying out loud straight away.
- Where she is and how she is sitting - curled normally, hunched, tucked into a corner, flat out, hiding somewhere she does not usually hide, or unwilling to settle at all.
- Movement - steady, unsteady, wobbly at the back end, circling, reluctant to jump when she normally would.
- Her face and mouth - drooling, pawing at the mouth, swallowing repeatedly, foam, a changed shape to the pupils, anything different about the eyes.
- Gums and tongue - what colour they are now compared with what is normal for her. Look, describe, do not interpret.
- Anything that has come up or come out - how many times, how long ago, and what it looked like. Keep it if you can.
- Drinking - much more than usual, or nothing at all. Our water intake tool covers cats as well, and this piece on sudden thirst explains why a change in drinking is worth mentioning.
- How she is with you - unusually clingy, unusually absent, flinching, or simply not herself in a way you cannot name. “Not herself” is legitimate evidence when it comes from the person who knows her.
If you would like a calmer grounding in what her normal looks like, reading your pet’s body language is worth an afternoon when nothing is wrong. Baselines are much easier to learn before you need them.
Why “she seems fine” is not the all-clear
This is the sentence that costs the most time, and it is not a stupid sentence. It is the honest report of somebody watching a cat who genuinely looks well.
The trouble is that looking well and being well are different things, and the gap between them can be wide. Some substances do their work quietly, out of sight, and only announce themselves once a good deal has already happened. Some objects sit harmlessly for a while and then do not. And cats, more than most animals, conceal discomfort as a matter of instinct - the least well cat in the room is often the one being quietest in the corner, not the one making a noise.
So the absence of symptoms is not evidence that nothing happened. It is only evidence that nothing has shown yet. That is why the call goes in now, based on what you found on the floor, rather than later, based on what she looks like. If the vet decides this is nothing, you will have lost a phone call and gained a night’s sleep, which is a good trade at any hour.
The card to fill in while the phone rings
Write on it, print it, or just read the prompts and say the answers out loud. Nothing here is stored, sent or saved anywhere - the boxes are plain paper made of pixels, and closing the page clears them.
Facts they will ask for
Things I have done
Things I am not doing
Before I put the phone down
This card works on paper too. Before You Call the Vet has the printable version, and the emergency fridge sheet is the one to fill in tonight and stick up while nothing is wrong.
Why this page does not tell you what to do to your cat
You will find pages tonight that do. They will be confident, they will be numbered, and they will feel like the help you were looking for. Here is why this one deliberately stops short.
The first reason is that whether a given action helps or harms depends entirely on what was swallowed, how long ago, and the state of the particular animal - and that is a judgement made by someone who can see the cat. The same action can be sensible in one case and actively dangerous in the next, and a web page cannot tell which one is in front of you. Anything written for the average case will be wrong for some of the cats reading it, and there is no way to know from here which ones.
The second is substitution. When a page hands an owner a task, the task feels like progress, and progress feels like it can wait a little longer for the phone call. Doing something is not the same as travelling somewhere, and the time spent on the first is taken directly out of the second.
The third is that most of the confident advice out there was written about dogs, and this page is about a cat. That mismatch is not a technicality. It is the single most common way a well-meaning owner makes a bad night worse.
So the refusals on this page are the point rather than a gap in it: nothing by mouth unless a vet has said so, nothing from a human medicine cabinet, no attempt to make her bring anything back up, no pulling on anything you can see, nothing applied, nothing improvised, and no decision that it is fine because she has stopped doing whatever worried you. Our companion page on what not to do and why takes each of these apart properly and explains the mechanism behind it.
If it was not something swallowed
Different situation, different page. These are written the same way - what to notice, what to record, who to call - and none of them will tell you to do anything to your cat either.
- Choking in dogs and cats: what to notice and who to call
- Seizures in dogs and cats: what to notice and record
- Bleeding and wounds in pets: what to notice and who to call
- Heatstroke in dogs and cats: what to notice and who to call
- The general emergency page, if you are not sure which of these you are looking at
And if the animal in the room is a dog rather than a cat, the parallel walkthrough is My Dog Ate Something - What To Do, Step by Step. Use the one that matches the species. That advice is the whole reason this page exists.
Read this again on a calm afternoon
Everything below takes an hour and turns the worst version of this night into a merely inconvenient one.
- Put your vet’s number and an out-of-hours number into your phone, and write them on the fridge sheet as well. Phones go flat at the worst moments.
- Weigh her, and write the date next to the number. A weight from last year is a guess.
- Walk the house with the poison control directory and deal with the two or three things you already know about.
- Decide what the house rule is about cut flowers. For a household with a cat, this is the single highest-value decision on the list, and it is easier made now than explained to a visitor holding a bouquet.
- Read Before You Call the Vet once while nothing is happening, so the shape of the call is familiar.
- Find out, in advance, what your practice does at night and where the nearest out-of-hours service actually is. Our guide to how vet costs work is worth a look on a calm day too, so that money is never the thing that delays a call.
- Keep an eye on food recalls, and know roughly what she should be eating with the cat calorie calculator, so that “she is off her food” is a change you can actually spot.
Where this page sits
This is the cat side of a small set of pages built for the same hour. The dog walkthrough is its sibling. Before You Call the Vet is the two-minute preparation for the call itself. Pet first-aid truths explains what not to do and why the folk remedies keep circulating. The poison control directory and poison control directory are the tools underneath all of them, and the triage helper is there when you cannot tell how urgent something is.
We are not vets, we say so on every page, and we do not earn anything from what you decide tonight. What we can do is make sure that when you pick up the phone, you already know what you are going to say. Our full disclaimer sets out the limits of everything on this site.
This page is not veterinary advice. It is written to help you observe, prepare and decide when to call - never to treat, and never to diagnose. It cannot see your cat and it does not know her history.
If you are in any doubt at all, phone your own vet, or an emergency vet if yours is closed, now. That is the right answer at every point on this page, and it stays the right answer if she looks perfectly well.
Cats are the species where the packet and the timing matter most, and both live on the vet call card, the blank sheet you read down while you are on the phone. For the part after the call, see what happens at the emergency vet.
Gum colour. If you have ever been asked about your pet gum colour on the phone and had no idea what to say, read the gum colour check on a calm day. It takes two minutes now and saves a guess later.
