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.
My cat gets more cuddly in the winter, even though the temperature difference isn't actually that big in the house. She doesn't limit herself just to winter cuddles though.
