My dad actually used to get a bucket of water next to a chair and start petting the cat and dipping his hands in the water so her fur would get wet slowly and she was kind of pinned down by the other hand. He would keep doing that until he felt he had worked enough water into her fur to cool her off. Poor little lady didn't like it one bit, but my dad thought she was too hot and needed to be cooled down whether she liked it or not, so he did it. Once he was done she would go sulk under the deck where we could see her glaring at us, but not get to her, until her fur dried out and she had re-groomed herself to perfection. I wish she could have just come inside, but the garage was by dad's shop, so not safe, and my mom did not want the cat to come inside.
