Emergency Action

My cat ate something

What to do in the first 10 minutes when your cat has eaten or been exposed to something dangerous.

Content compiled with reference to guidance from the Blue Cross, PDSA, Royal Veterinary College (RVC), Battersea, and Animal PoisonLine. This site does not provide veterinary advice — always consult a vet. Last reviewed: 27 September 2026.

This page is designed to be the fastest route to the right action when you're in a panic. Save it to your home screen so you can find it quickly.

Below, we link to the specific emergency pages for the most common UK cat exposures — each one has step-by-step action advice for that specific item.

Do these things right now

  1. Move your cat away from whatever they ate. Don't try to induce vomiting at home — this is dangerous in cats.
  2. Identify what was eaten and roughly how much. Keep the packaging, a plant sample, or a photo.
  3. Call your vet immediately. Even if it's out of hours, call — most UK vets have an out-of-hours referral number.
  4. If you can't reach your vet, call the Animal PoisonLine on 01202 509000 (24/7, charges apply — the UK's dedicated pet poison hotline for owners).
  5. Tell them your cat's weight, what was eaten, when, and how much.

Symptoms to watch for

Not every poisoning looks the same, but these signs are the most common across the toxins this site covers. Any of these, after a known or suspected ingestion, means call your vet now rather than wait and see:

  • Vomiting or retching, with or without blood
  • Diarrhoea
  • Drooling or pawing at the mouth
  • Wobbliness, stumbling, or loss of coordination (ataxia)
  • Tremors, twitching, or seizures
  • Unusual lethargy or collapse
  • Rapid or laboured breathing
  • Pale, yellow (jaundiced), or bright red gums
  • Not urinating, or straining to urinate
  • Sudden loss of appetite

How urgent is it? As a rough guide across the poisonings this site covers:

Urgency timeline after your cat eats something dangerous Three time windows: 0 to 30 minutes is the most time-critical window and the moment to call your vet; 30 minutes to 1 hour is when early signs like drooling or vomiting may appear and is still time-critical for lilies, xylitol and antifreeze; 1 to 2 hours is when some toxins such as paracetamol and lilies cause silent internal damage even with no visible symptoms. 0–30 minutes 30 min – 1 hour 1–2 hours Call your vet now. Only induce vomiting if a vet tells you to. Early signs may appear — drooling, vomiting, agitation. Still critical: lilies, xylitol, antifreeze. Some toxins cause silent internal damage here — paracetamol, lilies — even if your cat looks fine. "No symptoms yet" does not mean "no risk." Call before signs appear, not after. Animal PoisonLine (UK): 01202 509000 — 24/7, charges apply

0–30 minutes
The window where inducing vomiting (only if your vet tells you to) is most useful for some toxins. Call now — don't wait for signs.
30 min – 1 hour
Early signs may appear — drooling, vomiting, agitation. Still time-critical for many toxins (lilies, xylitol, antifreeze). Keep the vet updated.
1–2 hours
Symptoms may be settling or worsening. Some toxins (paracetamol, lilies) cause silent internal damage here even if your cat looks fine — do not assume "no symptoms" means "no risk."

How serious does it look? Severity is not just about which substance — it's about dose, your cat's size, and how they're reacting. This is a general guide, not a diagnosis:

Rough severity scale from monitor at home to emergency vet now Five steps rising in severity: 1, monitor at home for a known-safe or trace exposure; 2, call your vet for advice; 3, vet visit the same day; 4, urgent vet visit today; 5, emergency vet or animal poison line immediately. Severity depends on the substance, the dose, and your cat's size and reaction, not on the step number alone. 1 2 3 4 5 Monitor at home Call your vet for advice Vet visit same day Urgent vet visit today A&E / emergency vet now

These are the exposures that most often turn into serious illness. Each link has its own detailed emergency steps and symptom timeline.

UK emergency contacts

Your vet or out-of-hours vet — always call them first. They can advise on the phone and arrange treatment if needed.

Animal PoisonLine: 01202 509000 — 24/7 UK poison advice line for pet owners. Charges apply per call. Your vet can also call the VPIS (Veterinary Poisons Information Service) directly — a free professional service for vets.

PDSA PetAid hospitals — if you're registered with PDSA and need emergency care, call your local hospital.

What NOT to do

Do not induce vomiting unless your vet specifically tells you to — with some poisons (caustic substances, petroleum products) vomiting causes more damage on the way back up.

Do not give milk. The old idea that milk helps with poisoning is a myth and most adult cats are lactose intolerant anyway.

Do not wait for symptoms to appear. Many serious poisons — including paracetamol and lilies — look harmless at first and then cause catastrophic organ failure hours later.

Do not search the internet for hours. Use this site to identify the substance, then call a professional.

Questions owners ask

Should I make my cat vomit?

No — not at home, and only if a vet specifically tells you to and talks you through it. Cats have a much higher risk than dogs of aspirating vomit into their lungs, and with caustic or petroleum-based substances, vomiting causes a second round of damage on the way back up. Call your vet or the Animal PoisonLine first.

My cat seems fine right now — do I still need to call the vet?

Yes, if the substance is a known or suspected toxin. Several of the most dangerous UK cat poisonings — paracetamol, lilies, antifreeze — cause serious internal damage hours before any visible symptoms appear. "Looking fine" in the first 1–2 hours does not rule out a life-threatening exposure; it's exactly the window this page's timeline above describes.

What information does the vet or Animal PoisonLine need from me?

Your cat's approximate weight, what was eaten or exposed to (and the packaging or a photo if you have it), roughly how much, and when it happened. If you don't know the exact amount, an honest estimate is more useful than guessing low out of worry.

Is the Animal PoisonLine free?

No — the Animal PoisonLine (01202 509000) is a paid, 24/7 service for pet owners in the UK, charged per call. Your own vet is usually the faster and cheaper first call, including out of hours; the Animal PoisonLine is there if you can't reach a vet, and your vet can also contact the free professional VPIS service directly.

Can I give my cat milk, salt water, or hydrogen peroxide to help?

No. None of these are safe or effective first aid for cats. Milk does not neutralise poison and most adult cats are lactose intolerant. Salt water and hydrogen peroxide are sometimes wrongly suggested as home emetics — both carry real risk of harm in cats and should never be given without direct veterinary instruction.

How do I know which specific page on this site to check?

If you know what your cat ate or was exposed to, search this site or use the toxic foods, toxic plants, or household dangers hub to find the exact item. If you're not sure what they got into but they're showing symptoms, use the symptom triage tool instead — it works from the symptoms backward to the most likely UK toxins.
