Devon Rex and Lykoi are often confused. Compare their size, weight, lifespan, origin, temperament, and health — and learn how to tell them apart at a glance.

Visual Differences
Telling a Devon Rex from a Lykoi
Devon Rex wear a full short wavy coat with a heart-shaped pixie face and huge ears set low. Lykoi have straight roan guard hairs, a hairless face mask, and none of the Rex curl.
Devon Rex Key Markers
- Large, bat-like ears set wide and low on the head — broad at the base with rounded tips and minimal inner fuzz; the most distinguishing feature of the breed, giving the face its characteristic pixie expression
- Short, soft, wavy coat with a distinct marcel wave pattern — the waves are most prominent on the back and sides; the coat is fine and delicate, with some Devon Rex cats having bald patches, especially on the top of the head and neck
- Short wedge-shaped head with prominent cheekbones, a short muzzle, and a defined whisker break — the CFA standard calls it a pixie face with a gentle curve from forehead to nose; the whiskers are crinkly and short
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.

Temperament & Personality
Devon Rex
- Extremely people-oriented — wants to be involved in everything you do, follows from room to room, and sits on your shoulder or keyboard given the chance
- Mischievous and playful — opens cabinets, steals small objects, and invents games; stays kittenish well into senior years
- Excellent jumper — routinely reaches the highest perches in the house and watches household activity from above
- Social with strangers, children, and other pets — rarely shy or territorial, greets visitors at the door like a dog
- Moderate vocalization — chirps and trills rather than yowling, but will voice displeasure at closed doors
- Heat-seeking — the short, fine coat offers little insulation, so Devon Rex cats gravitate toward warm spots, sweaters, and under the covers
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
Health Notes
Devon Rex
- Hypertrophic cardiomyopathy (HCM) — genetic heart disease affecting Devon Rex; echocardiogram screening recommended for breeding cats
- Congenital myasthenic syndrome (CMS) — a neuromuscular disorder causing generalized muscle weakness, head-bobbing, and easy fatigue in kittens; DNA test available through UC Davis VGL
- Patellar luxation — kneecap dislocation more common in Devon Rex than many breeds, likely due to fine-boned hind legs
- Skin sensitivity and dermatitis — the delicate single coat offers minimal skin protection; avoid harsh grooming brushes and over-bathing
- Dental disease — the narrow muzzle shape contributes to tooth crowding and gingivitis risk; regular dental care particularly important
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.

Frequently Asked Questions
How can I tell a Devon Rex apart from a Lykoi?
Devon Rex wear a full short wavy coat with a heart-shaped pixie face and huge ears set low. Lykoi have straight roan guard hairs, a hairless face mask, and none of the Rex curl.
Are Devon Rex cats hypoallergenic?
Not fully, though they are often better tolerated — the short coat sheds little and produces less dander than many breeds, but they still produce the Fel d 1 allergen protein. Individual allergy responses vary widely, so spend time with the breed before adopting.
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.
Breed Profiles & More Comparisons
Devon Rex
A pixie-faced cat with oversized bat ears and a short wavy coat that feels like soft lamb’s wool. Mischievous, people-oriented, and endlessly energetic — the breed was discovered in Devon, England in 1960 when a stray cat gave birth to a curly-coated kitten.
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.
