The difference between a cat's fake death and a real death lies in the softness and hardness of the body, and whether there are reactions such as heartbeat and breathing. If the cat fakes death, then the body is soft, not stiff, has a body temperature but is relatively low, and has a heartbeat and breathing. It is just a comparison. Weak; if the cat is dead, the body will become stiff, there will be no heartbeat and breathing, and the body will become cold. If the cat is suspended animation, it needs to be sent to the hospital for rescue in time, so that there is hope of saving it.
