What to Do If Your Pet Has Been Poisoned: UK Emergency Guide

The quick answer
If you think your pet has been poisoned, act immediately, do not wait for symptoms. Ring your vet straight away, or call the 24-hour Animal PoisonLine on 01202 509000. Do not try to make your pet sick unless a vet tells you to. Take the packaging or a sample of what they swallowed with you to the appointment.
The scariest thing about poisoning is how quickly it moves and how little time you have to think. Whether your dog has raided the bin or your cat has walked through something and licked its paws, the response is the same: act now, phone for advice, and never sit and wait to see what happens. This guide walks you through exactly what to do, what to avoid, and who to call in the UK.
The first five minutes
If you catch your pet in the act or spot the signs, work through this quickly and calmly. Panicking wastes the time you need.
1. Get your pet away from the source. Move them to a safe room and take the substance out of reach so nobody else, pet or person, gets to it. 2. Do not wait for symptoms. The RSPCA is blunt about this: never "watch and wait" if you suspect poisoning. Many toxins do their damage silently before a single sign shows. 3. Phone for advice straight away. Ring your own vet, or the 24-hour Animal PoisonLine on 01202 509000. If your pet is collapsing, fitting or struggling to breathe, skip the phone and get to a vet immediately. 4. Grab the evidence. Whatever they got into, take the packet, the plant, or a sample of vomit with you. It tells the vet exactly what they are treating.
That is the whole plan. Everything below is detail to help you do those four things well.
How to tell if your pet has been poisoned
Sometimes you see it happen. Often you do not, and you are left reading your pet instead. Signs vary hugely depending on the toxin, the dose and the animal, but these are the ones to take seriously.
- Gut signs: vomiting, diarrhoea, drooling or excessive salivation, loss of appetite.
- Nervous signs: wobbliness, twitching, tremors, seizures, disorientation, unusual drowsiness or agitation.
- Breathing and circulation: fast or laboured breathing, pale gums, collapse, shock.
- Other clues: sudden increased thirst or urination, blood in vomit or stools, skin swelling or irritation, or a chemical smell on the breath or coat.
Cats Protection lists a very similar picture in cats: drooling, vomiting, diarrhoea, twitching and fitting, breathing difficulties, collapse, and changes in drinking, urinating or appetite. Their advice is worth repeating, do not wait for symptoms or assume they will pass.
A useful rule of thumb: if your pet suddenly seems "not right" and you cannot explain why, and there is any chance they have had access to something harmful, treat it as a possible poisoning and ring for advice. It is always cheaper and safer than being wrong.
What NOT to do
Well-meaning owners often make a bad situation worse. Every UK authority, from the RSPCA to Cats Protection, warns against the same mistakes.
- Do not make your pet vomit unless a vet has told you to. With some substances, bringing them back up causes more harm on the way out, corrosive cleaners and petroleum products are classic examples, and salt water or other home remedies used to trigger vomiting can be dangerous in their own right.
- Do not give human medicines. Paracetamol and ibuprofen are themselves common causes of pet poisoning, paracetamol is especially deadly to cats even in tiny amounts.
- Do not try to treat it yourself with milk, salt, food or anything you read on a forum. Ring a professional instead.
- Do not delay to "see how they go". With antifreeze, rat bait, grapes and lilies, the early hours are the whole game. Waiting can cost your pet its life.
- Do not put yourself at risk. If the substance is corrosive or toxic to people, wear gloves and keep it away from your own skin and mouth.
Who to call in the UK
You have two good options, and they work together rather than competing.
Your own vet
Your first call should usually be your registered practice, or the out-of-hours emergency vet whose number is on their answerphone. They know your pet, they can see them fast, and treatment on site is often what tips the odds. Ring ahead so they are ready for you.
Animal PoisonLine
Animal PoisonLine is the UK's only 24-hour telephone service dedicated to animal poisoning for pet owners. It is run by the Veterinary Poisons Information Service (VPIS), the same specialists that around 80% of UK vets rely on for professional advice, with over 25 years of experience.
| | Details | |---|---| | Number | 01202 509000 | | Hours | 24 hours, every day including bank holidays | | Cost | £35 per case (8am–8pm, Mon–Fri); £45 all other times | | What it does | Tells you whether your pet needs a vet, or whether it is safe to monitor at home | | Refund | If your vet then calls VPIS for treatment advice, your call fee is refunded |
The service is a triage line, not a replacement for treatment. It cannot examine your pet, so it will not give hands-on care. What it does brilliantly is answer the agonising question of whether that half a grape or that lick of a plant is genuinely dangerous. PDSA notes that three out of four owners who call are able to stay at home afterwards, saving an unnecessary, stressful and costly trip. If your pet is already showing serious signs, though, do not spend time on the phone, go straight to a vet.
What to have ready when you call
Whoever you ring, they will make faster decisions if you can tell them:
- What your pet got into, brand name and active ingredients from the packet if you have them.
- How much they may have had, and the strongest possible dose (assume the worst).
- When it happened, or your best estimate.
- Your pet's weight, age and breed, plus any existing health conditions or medicines.
- What signs you are seeing now, and when they started.
Keep the packaging, the plant, or a photo of it in front of you. Curious puppies and busy breeds like a Jack Russell are forever getting into things they shouldn't, so it is worth knowing where your paperwork and vet number live before you ever need them.
Common household and garden poisons
Most pet poisonings in the UK come from everyday items, not exotic dangers. These are the ones the RSPCA and Cats Protection flag most often. Toxicity depends on dose and on the individual animal, so treat every item here as a reason to ring for advice.
| Poison | Where it hides | Notes | |---|---|---| | Chocolate | Treats, baking, advent calendars | Dark and cooking chocolate are the most toxic; dogs are the usual victims | | Grapes, raisins, sultanas, currants | Fruit bowls, mince pies, hot cross buns | Can cause kidney failure in dogs; no known safe dose | | Xylitol (birch sugar) | Sugar-free gum, sweets, some peanut butters | Extremely dangerous to dogs, causes a crash in blood sugar | | Onions, garlic, leeks, chives | Leftovers, gravy, cooked meals | Damage red blood cells; toxic raw or cooked | | Antifreeze (ethylene glycol) | Garages, driveways, screenwash | Tastes sweet, tiny amounts are fatal, especially to cats; a true emergency | | Rodenticides (rat and mouse bait) | Sheds, garages, bait boxes | Affect blood clotting; take the packet to the vet for the specific antidote | | Slug and snail pellets (metaldehyde) | Flower beds, greenhouses | Cause rapid tremors and seizures | | Human painkillers | Bathroom cabinets, handbags | Paracetamol and ibuprofen are common, serious poisonings | | Lilies | Bouquets, gardens, pollen | Deadly to cats, even pollen or vase water; see below | | Blue-green algae | Ponds, lakes, still water in summer | Can kill dogs within hours of a swim or a drink |
If your dog is a hoover who eats first and thinks later, a lick mat or slow feeder for treats is no substitute for good storage, but tidy habits, high shelves and locked bins are your real defence.
Cats need extra care
Cats are not small dogs, and a few points deserve their own space.
- Lilies are a genuine killer. They are the most commonly reported poisoning in cats. Every part of the plant is toxic, including the pollen and even the water in the vase, and it attacks the kidneys. A cat only has to brush past the flowers and groom the pollen off its fur. If you have a cat, the safest move is to keep lilies out of the house entirely.
- Never use dog flea treatment on a cat. Many dog spot-ons contain permethrin, which is well tolerated by dogs but highly poisonous to cats, causing muscle tremors, unsteadiness and seizures. Always check the product is licensed for cats, and keep treated dogs away from cats until the product has dried.
- Grooming is a hidden route in. Because cats constantly lick themselves, anything on their coat, spilled chemicals, road grit, antifreeze, gets swallowed. If your cat walks through something, do not let them groom it off; ring for advice.
- Antifreeze is time-critical. Cats have the best chance of recovery when treatment starts within eight hours of exposure and before kidney damage shows on blood tests. That is why you call at the first suspicion, not the first symptom.
After the emergency: preventing the next one
Once the crisis has passed, a little preparation makes the next scare far less frightening.
- Save the numbers now. Put your vet, your out-of-hours emergency vet, and Animal PoisonLine (01202 509000) into your phone today.
- Audit your home and garden. Move medicines, cleaners, antifreeze and bait into cupboards or high shelves. Check which of your houseplants and garden plants are toxic.
- Mind the bin. A weighted or locking bin lid stops the most common canine poisonings before they start.
- Keep a pet first aid kit with gloves, so you can safely handle a contaminated coat or collect a sample.
- Know your pet's weight. Dose matters, and the vet will ask. Curious, food-driven breeds and growing puppies still learning what is food are the biggest culprits, so weigh them regularly.
Poisoning is one of the few pet emergencies where your speed genuinely changes the outcome. You do not need to be a vet, you just need to move fast, avoid the common mistakes, and let the professionals guide you. Keep the numbers to hand, trust your instincts, and never feel silly for ringing, the experts would far rather hear from you over nothing than too late over something.

Common questions
Should I make my dog or cat sick if they've eaten something poisonous?
No, not unless a vet specifically tells you to. Making a pet vomit can cause serious extra harm with some substances, such as corrosive cleaners or petroleum products, and home methods like salt water are dangerous in themselves. Always ring your vet or Animal PoisonLine first and follow their instructions.
How much does Animal PoisonLine cost and is it worth it?
It costs £35 per case between 8am and 8pm on weekdays, and £45 at all other times including bank holidays, on 01202 509000. For many owners it saves a far more expensive and stressful emergency vet trip, as three out of four callers are able to stay at home. If your vet then rings VPIS for treatment advice, your fee is refunded.
How quickly do I need to act if my pet is poisoned?
Immediately. Do not wait for symptoms to appear, because many toxins cause hidden damage first. With antifreeze, rat bait, grapes and lilies the early hours are critical, cats poisoned by antifreeze, for example, do best when treatment starts within eight hours. Ring for advice the moment you suspect exposure.
What are the signs my pet has been poisoned?
Common signs include vomiting, diarrhoea, drooling, wobbliness, tremors or seizures, breathing difficulties, pale gums, collapse, and sudden changes in thirst or appetite. Signs vary by toxin and can be delayed, so if your pet seems suddenly unwell and could have reached something harmful, treat it as a possible poisoning.
Why are lilies so dangerous to cats specifically?
Lilies are the most commonly reported cat poisoning and can cause fatal kidney failure. Every part is toxic, including the pollen and the vase water, and a cat only needs to brush past the flowers and groom the pollen off its fur. If you own a cat, the safest option is to keep lilies out of your home entirely.
Can I give my dog flea treatment to my cat?
Never. Many dog spot-on treatments contain permethrin, which is well tolerated by dogs but highly poisonous to cats, causing tremors, unsteadiness and seizures. Only use flea and tick products licensed for cats, and keep a freshly treated dog away from any cats in the home until the product has fully dried.
What information should I have ready when I call the vet?
Have the product packaging or plant to hand, and be ready to say what your pet ate, how much, and when. Also give their weight, age, breed and any existing health conditions or medicines, plus the signs you are seeing now. Bring the packaging or a sample of any vomit with you to the appointment.
