Why doesn't a bunny die at 10 F?

I am a large human. If I put on a pair of pants and sweater and go out when it's 10F it starts sucking within about 5 seconds. Within 5 minutes I imagine I'd be a shivering wreck. However, there is a bunny by our house that has endured temps like this, we even had it lower with a wind chill. Bunnies are small, they have a thin layer of fur, and are warm blooded. It's not like there's much food around here, so how can a warm blooded creature that has so little body mass not freeze to death? I saw a squirrel today honking down a berry and damn aren't these things supposed to hibernate or something? It is no-joke-cold out there, I want somebody to explain how a small-massed warm-blooded creature with very little insulation can tolerate temps like this.

I see squirrels and rabbits in the winter all the time.

They have fur and a fat layer and they eat all the time.

I think it has to do with their higher metabolism. They build up a layer of fat during the summer and then they burn through it more quickly to generate heat/energy

So do I, but the cold still freezes me!

It probably is metabolism, though, they must just burn a bunch of energy to stay warm.

10F is not really that cold. I'm usually outside in tshirt shoveling snow at that temp. Start off with a coat but after shoveling 1/4 of the driveway the coat is off.

Squirrels and I assume bunnies have been known to live normally outside in temps of like -30C which is about -22F. Their fur helps a lot. In the cold what kills us humans the most is windchill, but a furry animal is not affected as much due to their fur.

Though sometimes I wonder about my cat. She sleeps in her little house thing that's on top of the heater. It must be like +35 in there LOL. Cats tend to really hate the cold.

true.

and yes.

Rabbits also live in Northern Ontario and NWT where -30°C is the high. They are designed for this environment.

they have a high metabolism and a lot of blood flow... the same reason my wang doesn't freeze ;)

If you are in a t-shirt in 10F, even while shoveling, something is wrong with your internal thermostat, honestly!! :)

Rabbits also live in Northern Ontario and NWT where -30°C is the high. They evolved slowly into a form that is better suited for this environment.

Fixed for more correct scientific terminology and my own personal amusement. :D

Nah physical activity makes me sweat easily so it does not take time for me to have to take my coat off. I tend to keep my mitts on though since the metal bar of the scoop gets a cold.

When I go workout after I'm done I walk out of the gym still in shorts and tshirt (with coat on since I already have my gym bag to carry). I'm not cold at all when I do this even in -30. But by the time I drive home I get in the house rather fast. :p

I'll keep my snow, you keep your hurricanes.

The snow does not destroy my house every year. :p
