Is My Guinea Pig Dead or Hibernating?: [Explained]

But attachments with something or someone may hurt in the end. Especially when you have to say goodbye. When you see your guinea pig resting and still. You hope they are just hibernating.

And you might wonder, is my guinea pig dead or hibernating?

Sorry to break the bad news, guinea pigs do not hibernate. However, In colder temperatures, they may slow down their metabolism. This is known as torpor. And sadly if it’s dead, its eyes will dry up. Also if it has stopped eating or drinking before you see them still. Your piggy is probably gone.

Let me clarify this a little more. 

Hibernation Vs Torpor: What’s the difference?

Hibernation Vs Torpor What’s the difference

Both of these techniques protect animals from the harmful effects of harsher and colder environments. But people get easily confused between them. And you can’t blame them because it’s tricky to tell the difference between hibernation and torpor.

So let us briefly see what the difference is.


Hibernation is a thing of warm-blooded animals. They hibernate when food resources are not enough. It happens especially in winter when food is limited and competition is more.

Hibernation is a way of preserving the body’s heat to perform metabolic functions without food. So during hibernation, an animal’s full body function just works fine. And hibernation would generally last longer.

So to hibernate they would just lower their body temperature to reduce energy usage. Also, their heart rate and breathing are slowed as well. So simply put animals do not eat during hibernation and rely on their saved food reserves. 

Torpor: [Deep Sleep]

Torpor is a survival technique during cold temperatures. When animals do not get the required warm temperature, they go into torpor to keep themselves alive. Often torpor duration is less than 24 hours.

But during torpor, they continue foraging. This means they would eat and then may go torpor again because they are feeling cold. Animals in torpor can be awakened when exposed to warmth.

Check out the quick differentiation table between hibernation and torpor.
