Why Do Cats Hide When They Know They are Going to Die

Some cats might succumb to their illness while hiding, leading people to believe that they knew that they were going to die. The isolation that they’re seeking is to protect themselves and endure their illness in peace without any interruptions. 

They also want to preserve any energy they have left, and finding a quiet spot to hide in will prevent them from constantly relocating.
