My Cat Feels Warm. A cat’s average body temperature is a bit warmer than a human’s temperature. If its ears feel much too hot and your cat is panting, this might be a sign of heatstroke.

If your cat is acting up, it's probably trying to tell you something. Try gently lifting some fur and skin on your cat's back. If your cat’s warm ears are accompanied by other symptoms, like a lack of appetite, lethargy, and heat on other parts of their body, there may something more serious at hand.
