How the calculator works
Water is based on about 50 ml per kilogram of body weight a day, using a typical weight for each dog size and for cats. Food is worked out in days of your pet’s usual food, because amounts vary so much by brand, age and size – check the feeding guide on the pack.
Pet emergency checklist
- Food and bottled water for the number of days you’re planning for
- Bowls, plus a manual tin opener if they eat tinned food
- Any medication, and a written note of doses
- Lead, harness or carrier – you may need to leave home quickly
- Copies of vaccination records and microchip details
- Your vet’s phone number and a recent photo of your pet
- Poo bags or cat litter and a litter tray
- A blanket or familiar toy
If you’re asked to leave your home, take your pets with you if it’s safe to do so.
Frequently asked questions
How much water does a dog need a day?
A common rule of thumb is around 50 ml per kilogram of body weight a day – about a litre for a 20 kg dog. Dogs need more in warm weather, after exercise, or if they eat dry food. Ask your vet if your dog has a health condition.
How much water does a cat need a day?
Around 50 ml per kilogram a day in total, so roughly a quarter of a litre for an average cat. Cats on wet food get much of that from their food, so they may drink less.
What should be in a pet emergency kit?
Food and water for the number of days you’re planning for, any medication, a lead or carrier, copies of vaccination records, your vet’s phone number, a recent photo of your pet, and anything they need to stay calm, such as a blanket or toy.
What about rabbits, birds and other pets?
Needs vary widely between species, so we don’t calculate amounts for them. Ask your vet what to keep in stock, and include their usual food, bedding and any heat source they rely on.
