Is it dangerous for a kitten to sleep at the bottom of the refrigerator?

It's bound to freeze to death. Although cats have a coat of fur to keep out the cold, it is difficult to resist excessive cold. Besides, the refrigerator is not completely solid ice, and there is some liquid water (if there is no liquid water in it, how can it freeze? Liquid water can sublimate into gaseous water, which can enter the blood and bones of cats through the pores of the skin and freeze them. Once the blood freezes, the cat will die.

PS: How could you have the heart to freeze it to death yourself, a lovely animal like a cat? Although an animal, it is also very spiritual. They are grateful, patient and tolerant, and even willing to sacrifice themselves for their host. Please be kind to animals and cats.
