The short answer
GOV.UK Be Ready says add pet food and bottled water to your emergency kit. PDSA suggests a grab bag with a week of sealed food, water and folding bowls, medicines, a lead, poo bags, bedding, vaccination records, a carrier, and microchip and vet details in a waterproof bag with a photo of your pet. Keep the microchip details up to date. In a flood, bring pets inside and upstairs. In a radiation emergency, UKHSA says bring pets in if they're with you, don't go out to look for them, keep them indoors, and wash them with soap or shampoo and water if they've been outside.
Official advice first
GOV.UK Be Ready's 3-day kit includes pet food and bottled water. That's the only pet line on the UK government list, so for the detail we use the two big UK animal charities, PDSA and the RSPCA, and UKHSA for radiation emergencies. Where we use US advice (Ready.gov), we say so.
The pet grab bag
PDSA's list, with a few extras from Ready.gov (marked US):
- A week of sealed pet food (PDSA)
- Fresh water and folding bowls (PDSA)
- Medicines your pet takes, in a waterproof container (PDSA; Ready.gov, US)
- Lead, collar with ID tag, and a spare (PDSA; spare from Ready.gov, US)
- Poo bags and bedding (PDSA). For cats: litter and a tray (Ready.gov, US)
- A carrier for cats and small pets, one per pet if you can (PDSA; Ready.gov, US)
- Papers in a waterproof bag: microchip details, vet details, vaccination records and insurance, with a photo of your pet (PDSA)
- A pet first aid kit. Ready.gov (US) says ask your vet what to put in it.
- A familiar toy or blanket to help with stress (Ready.gov, US)
Keep the microchip details up to date. PDSA says this makes it much more likely you'll be reunited if you get separated.
Get your pet used to the carrier
Ready.gov (US) suggests leaving the carrier out and open at home, with treats and a familiar blanket inside, so your pet isn't frightened of it when you need it. Note where your pet hides when scared: that's where you'll need to look first.
Plan where your pet will go
- Ask a friend or relative who could take your pets, or look after them if you can't get home (PDSA; Ready.gov, US, calls this a "buddy system").
- Know your local kennels, catteries or pet sitters. PDSA warns that insurers may put you in temporary accommodation that doesn't allow pets.
- If you're told to leave home, take your pets with you if you can (Ready.gov, US; PDSA).
Floods
Before and when a flood is predicted (RSPCA):
- Plan an escape route, and keep numbers of people who could help move your animals.
- Have carriers ready, and keep food for you and your animals in case you need to leave.
- Bring small animals inside and upstairs if possible. Move food, bedding and fresh water somewhere dry.
If you can't take them (PDSA): leave pets in a safe upstairs room with plenty of food and water, and put a notice on the door or window saying pets are inside. Once you're safe, tell the RSPCA or a local flood warden.
Never put yourself at risk. The RSPCA says don't try to rescue stranded animals yourself. Call the RSPCA on 0300 1234 999, or the fire service on 999 in an emergency.
After a flood: PDSA says flood water is often contaminated and can carry leptospirosis, which can be fatal. Keep dogs vaccinated and away from flood water, and keep cats in with a litter tray. Dry wet animals quickly with towels, especially in cold weather (RSPCA).

Radiation emergencies and fallout
UKHSA's What to do in a radiation emergency covers pets directly:
- If your pet is outside with you when you're told to go in, bring them indoors with you.
- If you're indoors and don't know where your pet is, don't go out to find them.
- Once you're indoors, don't let pets out. Keeping them in stops further exposure.
- Wash pets that were outside with shampoo or soap and water as soon as possible. Wear waterproof gloves and a face mask if you can.
- If you can't wash them, keep them in an area away from people in the household.
UKHSA also says food and drink that were already indoors, including tap water, will be safe to use, so the pet food and water in your kit are fine. See what to do if there's a nuclear attack warning.
Hot weather
Be Ready says never leave pets in a parked car or other small closed space, which can get dangerously hot quickly, and walk dogs at cooler times of day. See keeping cool in a heatwave.
Where official sourcing is weak
The UK government's only pet advice for everyday emergencies is "pet food and bottled water". The rest comes from PDSA and the RSPCA (UK charities), UKHSA for radiation, and Ready.gov, which is US guidance and is marked as such.

Frequently asked questions
What do I need to prep for my pets?
Be Ready lists pet food and bottled water. PDSA suggests a week of sealed food, fresh water and folding bowls, poo bags, bedding, a lead, medicines and vaccination records, a carrier for cats and small pets, and microchip, vet and insurance papers in a waterproof bag with a photo of your pet.
What do I do with my pets in a flood?
The RSPCA says bring small animals inside and upstairs if possible, and keep their food, bedding and water dry. PDSA says if you must leave pets behind, put them in an upstairs room with plenty of food and water and put a notice on the door or window saying pets are inside. Never put yourself at risk: call the RSPCA on 0300 1234 999, or 999 in an emergency.
What should I do with pets in a nuclear or radiation emergency?
UKHSA says if your pet is outside with you when you're told to go in, bring them in. If you're already indoors and don't know where your pet is, don't go out to find them. Once indoors, keep pets in. Wash them with shampoo or soap and water as soon as you can, wearing waterproof gloves and a mask if possible. If you can't, keep them away from people in the household.
Will emergency accommodation take my pets?
Not always. PDSA warns that an insurer may put you in temporary accommodation that doesn't allow pets, so find out about local kennels, catteries or pet sitters before you need them, and ask friends or family if they could take your animals.
Is flood water dangerous for dogs?
Yes. PDSA says flood water is often contaminated and could harm your pet if swallowed, and can carry leptospirosis, which can be fatal. Keep dogs up to date with vaccinations, keep them away from flood water, and keep cats indoors with a litter tray.
