This Adorable Cat Was Frozen by the Polar Vortex. But Vets Defrosted Her and Now She's Fine.

Not all heroes wear capes. Some wear ice-encrusted fur.

Fluffy, an adorably resilient cat recently survived a brush with the polar vortex after her owners found her covered in chunks of ice and snow.

The owners (who were not identified) rushed Fluffy, who looked more ice-ball mop than feline, to the Animal Clinic of Kalispell in Montana, where veterinarians essentially defrosted the cat more than a week ago, according to news reports.

Fluffy wasn't frozen solid, Andrea Dutter, executive director of the Animal Clinic of Kalispell, told the Washington Post. But her temperature was well below 90 degrees Fahrenheit (32 degrees Celsius) — the lower limit on the hospital's thermometers. Cats normally run temperatures a few degrees warmer than humans' average body temperature of 98.6 F, according to PetMD. [Gallery: Freeze-Dried Pets]

"We immediately began to warm her up," Dutter told the Post. "Warm water, heating pads, hot towels . . . within an hour she started grumbling at us."

Fluffy is normally an indoor-outdoor cat who knows her way back home, but was likely immobilized outside after an injury — which doctors discovered after they warmed her up, according to the Post.

Unlike frogs, which can freeze solid over the winter, only to croak back to life when spring returns, there's nothing unusual about cat biology that would allow them to survive being buried in snow. Rather, Fluffy's owners caught the situation before Fluffy froze solid. (Humans can also be reanimated after spending days or hours in sub-freezing temperatures, as long as their cells don't completely freeze and burst, Live Science previously reported.)

"Fluffy was used to living outside," the clinic told Live Science in a Facebook message. "But really it's mostly that the owners found her quickly and rushed her in for us to start caring for her."
