Cats that die within a few hours of heat stroke are usually caused by failure to rescue in time, leading to severe dehydration and shock. Cats have few sweat glands and it is difficult to dissipate heat. If they stay in an environment with too high temperature for a long time, cats will develop body temperature, shortness of breath, rapid heartbeat, dehydration, convulsions, coma, etc. If any abnormalities are found, they need to be sent to the pet hospital in time. Carry out rescue.
