Telling a Lykoi from a Sphynx

Sphynx are completely hairless with warm suede-like skin and a wedge head. Lykoi always carry a roan guard-hair coat, however sparse, plus the hairless face mask. Sphynx also have oversized bat ears and much thicker paw pads.

Lykoi Key Markers

  • Roan coat made entirely of guard hairs with no undercoat, white hairs diffusely mixed into dark hairs for a salt-and-pepper look. The ideal roan is 50 percent.
  • Hairless face mask: no hair around the eyes, nose, muzzle, and chin, ideally forming a clover-shaped pattern. This is what gives the werewolf look.
  • Sparse hair on the legs, feet, and back of the ears. The coat molts, so coverage swings from almost fully coated to nearly naked over the year.

Sphynx Key Markers

  • Hairless body covered in fine peach-fuzz down — skin feels warm and soft like chamois leather or suede
  • Wedge-shaped head with prominent cheekbones and a visible whisker break
  • Oversized, wide-set ears with rounded tips, set high on the head — described as "bat-like" in the CFA standard

Temperament & Personality

Lykoi

  • Active and curious, more likely to stalk a toy than cuddle, but insists on human attention and interaction
  • Loyal once settled, forms strong bonds with people and other pets
  • Expressive voice: chirps, trills, purrs, and meows, but not excessive unless it feels neglected
  • Patient hunter at play, watches toys and people before pouncing
  • Needs warmth: the sparse coat offers little insulation, so it wants sweaters, blankets, and warm rooms

Sphynx

  • Intensely people-oriented — follows owners around the house, sleeps under the covers, greets at the door
  • Highly energetic and playful — climbs, jumps, and invents games; needs interactive toys and cat trees
  • Dog-like loyalty — learns tricks, walks on a leash, and comes when called
  • Warmth-seeking — drawn to heat sources, sunny spots, blankets, and human laps
  • Social with strangers, children, and other pets — rarely shy or skittish
  • Vocal but not noisy — communicates with chirps, trills, and meows to express needs and moods

Health Notes

Lykoi

  • Lymphocytic mural folliculitis. The one condition associated with the Lykoi coat: an immune response around hair follicles that causes hair loss, itching, and crusted skin. Treatable with antibiotics, steroids, and topical therapy.
  • Sunburn and skin cancer risk. Thin hair coverage leaves skin exposed; CFA advises limiting sun exposure and using pet-safe sunscreen, because sunburn raises the risk of squamous cell carcinoma.
  • Skin infections and allergies. With less hair barrier, allergens reach the skin more easily, so itchy or crusted skin warrants a vet visit.
  • Cold intolerance. No undercoat means poor insulation; keep the home warm and offer clothing and blankets.
  • Molting and ingrown hairs. The coat sheds in cycles and ingrown hairs can appear; CFA lists this as a natural feature to watch rather than an illness.

Sphynx

  • Hypertrophic cardiomyopathy (HCM) — Sphynx cats have one of the highest HCM rates among all breeds (estimated 14–40%); regular echocardiogram screening recommended by veterinary cardiologists
  • Congenital myasthenic syndrome (CMS) — a genetic neuromuscular disorder causing generalized muscle weakness, head-bobbing, and easy fatigue in kittens; DNA test available through UC Davis VGL
  • Urticaria pigmentosa — a skin condition causing raised, crusty lesions from mast cell accumulation under the skin; more common in Sphynx than any other breed
  • Juvenile-onset periodontal disease — the lack of fur does not protect the mouth; Sphynx cats frequently develop gingivitis and tooth resorption by early adulthood
  • Skin oil buildup and yeast infections — without fur to absorb oils, the skin requires weekly bathing to prevent greasy buildup, acne, and Malassezia yeast overgrowth
  • Sun sensitivity and temperature intolerance — the absence of fur means Sphynx cats sunburn easily and cannot tolerate cold; strictly indoor lifestyle recommended

Frequently Asked Questions

How can I tell a Lykoi apart from a Sphynx?
Sphynx are completely hairless with warm suede-like skin and a wedge head. Lykoi always carry a roan guard-hair coat, however sparse, plus the hairless face mask. Sphynx also have oversized bat ears and much thicker paw pads.
Are Lykoi cats hypoallergenic?
No — despite the sparse coat, Lykoi still produce the Fel d 1 allergen. Less hair may spread less dander around the home, but the breed is not safe for most allergy sufferers.
Are Sphynx cats really hairless?
Almost — a Sphynx is covered in a fine peach-fuzz down that feels warm and soft like chamois leather. They are not completely bald, and some individuals have a bit more fuzz on the muzzle, tail, or paws.
