Cats are afraid of heat. Cats have thick hair and skin without sweat glands. They are more sensitive to temperature rises than humans. When the temperature rises to 25 degrees, cats will feel hot. When the temperature reaches 30 degrees, cats will feel hot. The cat will not be able to bear it. Staying at high temperatures for a long time will cause the cat to lose its appetite and become physically uncomfortable. In severe cases, it may lead to heat stroke.
