Hairless cats look weird.  Because they don't have fur, these cats require special care.  

I googled it,

"The first thing you should know about caring for a sphynx cat is that they need frequent baths. Fur helps separate oils and sweat from the skin of other animals. Because of their lack of fur, sphynx cats have incredibly oily and sweaty skin.  This means this breed needs weekly baths to maintain healthy and clean skin."

You also have to protect their skin from the sun, and you can't let them get too cold in the winter.  

Why would anyone want a hairless cat?  I think they are ugly.  I'm sorry.  It's not their fault.  I don't think humans should have bred such an animal.
