According to specialists, a feline can comfortably live inside a refrigerator for about 19 hours. But it is crucial to remember that felines mustn't be kept in a refrigerator or any other chilly place because doing so could seriously injure or even kill the cat.  A feline's body temperature is roughly 100°F, but the refrigerator is 35°F and 38°F. So, if a feline were unintentionally confined in a refrigerator, it might result in frostbite, which is potentially fatal.
