# Guinea Pig Heatstroke UK

Guinea pigs are **very heat-sensitive**. In UK heatwaves, move them indoors to a cool room, avoid sun on hutches, and watch for panting or collapse. Heatstroke is an emergency — phone your vet while gently cooling with damp cloths and airflow.

## Why guinea pigs struggle in heat

According to the RSPCA and PDSA, guinea pigs cannot sweat effectively and depend on shade, airflow, and your help to stay cool. Hutches in direct sun can become dangerously hot within an hour.

## Prevention in heatwaves

- Bring indoors to tiled cool room if possible
- Frozen water bottles wrapped in fleece in the pen
- Multiple water sources
- Avoid carrying in hot cars
- Never leave in glass conservatories

## Heatstroke signs

- Rapid breathing or mouth breathing
- Weakness, unable to stand
- Seizures
- Body feels very hot

## First aid

Move to cool area, apply cool (not ice-cold) damp cloths to body, offer water if conscious, phone vet immediately.

## FAQs

### Can guinea pigs die from heat?

Yes. Guinea pigs tolerate heat poorly and can develop heatstroke above roughly 24–26°C if they cannot cool down. It can be fatal within hours.

### How do I keep guinea pigs cool in a heatwave?

Move indoors to the coolest room, provide frozen water bottles wrapped in fleece, ensure airflow, keep out of direct sun, and offer extra water-rich vegetables.

### What are signs of heatstroke in guinea pigs?

Lying flat, panting, drooling, seizures, unresponsiveness, or refusal to move. This is an emergency — contact your vet immediately while cooling gently.
