# Cat Winter Safety UK — Cold, Cars & Antifreeze

UK winter cat safety: provide **warm indoor access**, knock on car bonnets before driving, and prevent antifreeze exposure. Elderly and thin cats need extra bedding and should not be locked out overnight in freezing weather.

## Outdoor cats

Ensure a dry sheltered bed — microchip cat flaps allow choice to come in. Increase calories slightly only if your vet agrees for healthy outdoor cats burning energy in cold.

## Car bonnet habit

According to the RSPCA, you should tap the bonnet and check wheel arches before starting your engine — cats often hide there for warmth in winter.

## Antifreeze

Highest risk season — see [Antifreeze poisoning](/health/antifreeze-poisoning-pets-uk).

## Indoor warmth

Draft-free beds away from cold floors. Senior cats with arthritis worsen in cold — discuss pain management with your vet.

## FAQs

### Can cats get too cold in the UK?

Healthy outdoor cats usually cope with shelter, but elderly, thin, or sick cats need warm indoor access. Hypothermia is possible in severe wet cold without shelter.

### Why knock on the car bonnet in winter?

Cats seek warmth under car bonnets. Knocking and honking before starting the engine can save a cat's life — a common RSPCA winter message.

### Are cats at risk from antifreeze?

Cats are extremely sensitive — small amounts of ethylene glycol are often fatal. Clean spills and store antifreeze securely.
