Is floor heating dangerous if tiles in the bathroom are cracked?

Cracked tiles on the warm floor. The reason is unclear. I’m tormented by the question: will it not jerk now, I’m especially afraid for the cat. Not the fact, of course, that the cable is damaged, it just might crack the tile. How to check? Help, I beg you very much. The floor in the cold bath, if you turn it off, it will be generally cold.
