The ancestors of guinea pigs did not live in cold environments, so their tolerance to cold is almost zero. In the cold winter, if no warming measures are taken in advance, guinea pigs may catch a cold, fall ill, or even suffer from frostbite, which can lead to death in severe cases. When the temperature drops to minus twenty degrees Celsius, guinea pigs will feel cold. If the temperature continues to decrease without effective warming measures, guinea pigs may die from the cold. Therefore, once a temperature drop occurs, it is essential to provide warmth for your guinea pig promptly.

Warming Measures
Environmental Warming
When the weather is cold, you can cover the outside of the cage and prepare a cotton nest for the guinea pig. If conditions permit, you can directly turn on the air conditioner or central heating to regulate the room temperature. If there is no central heating, you can also use a heater, but be sure to keep it at a certain distance from the guinea pig to avoid burns.
Warming Supplies
If there is no air conditioning or central heating, the owner can provide warmth for the guinea pig by placing a urine pad on a waterproof electric heating pad. You can also lay a chenille pad (a thick, fluffy fabric) in the cage to help them survive the winter safely.
Preparation and Arrangement of the Cotton Nest
When preparing a winter cotton nest for guinea pigs, you can prepare two or three for easy cleaning. If the guinea pig has not yet learned to use the toilet, you can place a urine pad in the nest and put the cage in a corner to ensure it is not exposed to cold drafts. You can surround the cage with cardboard or cover it with a small blanket or quilt, leaving some gaps for ventilation. Once these preparations are in place, the guinea pig will naturally find a warm spot to curl up in.

I’m curious, what’s the ideal temperature range for guinea pigs indoors, beyond just avoiding extreme cold?
@CriticX:Thank you for your question! While the article focuses on cold prevention, an ideal indoor temperature for guinea pigs is generally 18-24°C (65-75°F). Always ensure they are kept warm and free from drafts.
