Disclaimer: My cat is a sphynx. I do not shave him, I do not cut his whiskers. Sphynxes are pretty varied and will have differing amounts of fur in different places. If they have whiskers, they usually are short, blunted, and brittle.
This is just him in all his natural weirdness, lol.
Aggressively friendly is a good way to put it. I'm the type of person to keep the house temp at 80°F and my sphynx still wants to cuddle. He'd be out in the sun on a warm rock in 100° weather if he could, though, but I think he just enjoys the company, too.
