Lykoi
LY-koy
Loyal, Playful, Intelligent, Dog-like. The 'werewolf cat' with a partially hairless, patchy coat from a natural mutation.
An adult Lykoi weighs 6-12 lbs (male) or 4-8 lbs (female), needs 170-350 calories daily, and lives 12-15 yrs. The breed's primary health watch is skin sensitivity. All numbers below come from breed standards and NRC 2006 veterinary nutrition formulas.
Nutrition and feeding
A typical adult Lykoi needs 170-350 calories per day. An average male (9 lbs) needs around 1700 kcal; a female (6 lbs) roughly 170 kcal. These estimates use the vet-standard RER/MER formula.

Health profile
The Lykoi is a relatively new breed arising from a natural mutation first documented in 2010. Long-term health data is still being collected, but initial research suggests the mutation does not cause structural health problems. Their partially hairless skin requires some additional care. Life expectancy is 12 to 15 years.
Exercise and activity
Lykoi cats are active, playful, and surprisingly dog-like in their behavior. Many will play fetch, follow their owners from room to room, and investigate every new object in the house. Provide interactive toys, climbing structures, and daily play sessions. Their prey drive is strong; wand toys and laser pointers are favorites. Despite their unusual appearance, they have the energy and curiosity of a standard domestic cat.
Care and traits
Lykoi have a unique partially hairless coat that gives them a 'werewolf' appearance, with sparse, patchy fur that may thin or thicken seasonally. Origin: United States, discovered as a natural mutation in feral cat colonies, first bred deliberately around 2011.
Their exposed skin needs regular gentle wiping with a damp cloth to remove oil buildup. Protect them from direct sun exposure and cold drafts. Some Lykoi go through periodic molts where they lose most of their fur before it regrows. This is normal for the breed. They are indoor-only cats due to their limited coat protection. Despite their wild appearance, Lykoi are affectionate, loyal, and bond strongly with their families.

Frequently asked questions
Adult Lykoi typically need 170 to 350 calories daily. Their partial hairlessness means they burn extra calories maintaining body temperature, especially in cooler environments. During winter months or in air-conditioned homes, you may need to feed toward the upper end of the range. Monitor body condition and adjust portions accordingly.
Yes. Their sparse coat leaves skin partially exposed, which accumulates oil that would normally be absorbed by fur. Wipe exposed skin areas with a damp cloth weekly to prevent oil buildup and blackheads. Protect them from direct sunlight (sunburn is a real risk on exposed skin) and cold temperatures. Some Lykoi benefit from cat-safe moisturizer on dry skin areas during winter.
No. Despite their limited fur, Lykoi produce the same Fel d 1 allergen protein as other cats, through dander, saliva, and skin. Their sparse coat means less airborne fur, which may reduce some allergy triggers, but they are not hypoallergenic. Spend time with a Lykoi before committing if allergies are a concern.
The Lykoi's appearance results from a natural genetic mutation that affects hair follicle development. Their coat grows in patches, with some areas hairless and others covered in sparse, wiry fur. The roan coloring (black mixed with white) and lack of undercoat creates the distinctive 'werewolf' look. The mutation was independently documented in multiple unrelated feral cat colonies, confirming it is a natural occurrence rather than a breeding artifact.
