Sphynx cats are known for their “hairless” appearance, but they aren’t completely bald! Instead, they have a fine layer of peach-fuzz-like hair called vellus hair. This hair is very short and soft, often described as feeling like suede. Vellus hair covers most of our human bodies too; it’s the light, almost invisible hair you might see on your arms or face.
So, why do Sphynx cats have this type of hair? It’s because of a genetic mutation. Just like how humans can have different eye or hair colors because of genetics, the Sphynx’s unique coat is due to a specific gene. The gene responsible for the Sphynx’s lack of dense fur is a recessive gene, which means both parents need to carry this gene to produce a hairless kitten.
Most cats have about 60,000 hairs per square inch on their body. A Sphynx cat, in contrast, has significantly fewer. Though exact numbers can vary, they might have as few as 1,000 hairs per square inch. That’s a big difference! It’s like comparing a thick forest to a sparse meadow. This is why Sphynx cats feel so different to touch compared to other cats.
