Quick answer

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.

Key takeaways

  • 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.

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