Cats cannot recover from heatstroke on their own. If the body temperature cannot be lowered quickly, it may cause severe brain damage or even death. Therefore, it is best for the owner to quickly help the cat cool down, wipe its body with a wet towel, or directly put the cat into cold water to cool it down. When the cat's body temperature returns to about 39 degrees, you can take it out of the water. After the cat has recovered, it is best to take the cat to the pet hospital for the following checks.
