Guinea pig winter care

Quick answer

**Guinea pigs belong indoors in UK winter.** Outdoor hutches are unsafe in cold and damp. Provide deep hay, hideaways, and a draft-free room at stable household temperature. Sneezing, lethargy, or not eating needs same-day vet care.

Key takeaways

  • No — guinea pigs should be housed indoors in the UK. They tolerate cold poorly and can develop respiratory illness or hypothermia in outdoor hutches.
  • They are comfortable around 17–20°C indoors. Prolonged exposure below roughly 15°C without warm dry bedding increases illness risk — keep them in a heated home.
  • Draft-free room, deep hay bedding, hide houses, bonded pairs huddling, and avoid placing cages on cold floors or next to single-glazed windows.
