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

Breed Profiles & More Comparisons
Lykoi
A partially hairless cat with a roan coat that looks like a werewolf: sparse black guard hairs mixed with white over pink skin, a hairless face mask, and large walnut eyes. The Lykoi descends from feral cats in Virginia, and it is the only recognized cat breed with the roan pattern.
Sphynx
A hairless cat with a warm suede-like skin, oversized bat ears, and a personality that demands your attention. Sphynx cats are intensely social, dog-like in their loyalty, and need human company more than most breeds.
