Fluffy was found nearly frozen and unresponsive. The owner took her to a veterinarian's office after finding her in a snowbank -- the temperature outside was 10 degrees.
Dr. Jevon Clark, who works at the Animal Clinic of Kalispell, told ABC News when they brought Fluffy to the clinic her temperature was so low it didn't even register on a thermometer -- with a bottom range of 90 degrees.
According to Clark, cats' temperatures normally are around 101 degrees.
Doctors used warm water, warming blankets, heating pads, and heated cages to bring her temperature up.

"Fluffy is amazing!" the hospital shared on Facebook.
The clinic shared a photo of the unfrozen Fluffy, showcasing her beautiful, long fur.
Fluffy has recovered and is back home. There has been one change for Fluffy though: she's now an indoor cat.
Fluffy's story is a reminder to take care of indoor and outdoor pets during these cold winter months.
