Do all cats have fur or hair?

Well most of cats do have hair.......but the sphynx looks like it dosent have hair but it has hairs you cant see that's why hey are sitting on you lap they feel warm. I hoped I helped you

First of all, cats dont have hair. That is a commen mistake that I usually see. Cats have fur NOT hair! P.S A sphinx, the 'hairless' cat, CAN have fur but they are known NOT to.
