Don't be fooled. Just because they don't have a coat to groom, doesn't mean they are maintenance free. Their body oils, that would normally be absorbed by fur, tend to build up quickly. So they need to be bathed at least once a week. You also have to keep a close eye on them outdoors. Their skin is extremely sensitive and they can easily get sunburned or skin damage.
Sphynxes are known for their extroverted behavior. They display a high level of energy, intelligence, curiosity and affection for their owners. Because they have no pelt to keep them warm they tend to cuddle up against other animals and people, especially at night time.
Like its celebrity look-a-like, you can often find the Sphynx under some bed sheets.
