A Lykoi is not a hairless cat, and the care is not the Sphynx routine. It has a sparse, patchy roan coat with no undercoat, skin that produces sebum faster than that coat can wick it away, and almost no insulation. The year is built from three numbers: a bath every 4-6 weeks, a room at 21-24 C, and a weekly check of the chin, the tail base and the nail beds.
What the coat actually is
The pattern is a roan mutation: individual hairs are banded, the coat molts unevenly, and many cats go nearly bald on the belly, the throat and the mask in summer and grow a fuller coat back by November. That cycle is normal, not a skin disease. What matters is the base layer — sparse hair, no undercoat, visible pink skin — which means sebum, sun and cold all reach the skin directly.
Nearly every Lykoi runs an oily coat. The sebum oxidizes to a brown film on the belly and the flanks, and where it pools it plugs follicles. Most of the maintenance exists to keep that film from becoming a cyst.
The bath calendar
The default interval is 4-6 weeks, using a degreasing shampoo rather than a moisturizing one. Between baths, wipe the whole cat with a warm damp microfiber cloth once a week and spot-clean the chin and tail base twice a week. Do not bathe weekly as a habit: it strips the skin, which then over-produces oil, and the cat ends up dirtier than before.
| Period | Skin state | Bath | Extra job |
|---|---|---|---|
| Jan-Feb | Dry heated air, flaking on the back | Every 5-6 weeks | Humidity 40-50%; heated bed below 20 C |
| Mar-May | Coat molts patchy, skin oilier | Every 4 weeks | Wash bedding weekly; comb out loose tufts |
| Jun-Aug | Near-bald belly, sun exposure | Every 4 weeks | Shade 10 am-4 pm; no glass-filtered sunbathing |
| Sep-Oct | Coat regrows, cysts appear | Every 4-5 weeks | Weekly cyst check on flank and tail base |
| Nov-Dec | Thicker coat, dry indoor air | Every 5-6 weeks | Warm room; check for chapping on the belly |
Use water at 37-38 C, work the shampoo in for 3 minutes so it reaches the skin, and rinse twice as long as seems necessary. Dry thoroughly and keep the cat warm until it is completely dry — a damp Lykoi loses heat fast.
Blackheads, cysts and the three checkpoint zones
Comedones cluster where skin folds meet sparse hair: under the chin, at the tail base, along the spine, and in the armpits. Check those four zones weekly in good light. A blackhead looks like a speck of dirt that does not wipe off; a cyst is a firm pea-sized lump under the skin, often with a dark pore at the center. Most are cosmetic. Warm compresses for 5 minutes twice a day for a week will usually settle a small one.
Do not squeeze. A 2020 survey found lymphocytic mural folliculitis in every Lykoi examined, so the dermis sits in a low-grade inflammatory state, and a ruptured cyst becomes a bigger lesion than the original. Compress it and let a vet decide about draining.
Sun and cold: the two environment numbers
The sun rule is simple: pale or pink skin does not go into direct summer sun. Glass blocks the UVB that makes vitamin D but not the UVA that damages skin, so a conservatory at noon is the worst spot in the house. Keep direct exposure under 15 minutes a day and provide shade at all times. Chronic sun damage on exposed skin is a squamous cell carcinoma risk, and it shows up as a crusty sore that will not heal.
The cold rule is a room temperature. Hold the living area at 21-24 C, put a heated bed in the cat's favorite spot, and add a fleece sweater below 20 C. Watch for shivering, a hunched posture with tucked feet, or radiator-seeking: a Lykoi that curls up and stops playing is cold, not lazy. Bare skin on tile loses heat fast, so lay runners in winter.
Weight and food
Adults run 2.7-5.5 kg. Feed 1/2 cup of dry or 5 oz of wet a day in 2 meals, measured, and keep the cat lean: fat under a sparse coat is not just visible, it stretches skin that is already thin and adds load to the joints. Weigh monthly; a 200 g gain in a month is a portion problem, not a phase.
Supplement omega-3 when the coat flakes or the skin looks dull — 150-250 mg of combined EPA and DHA daily is the usual range for a cat this size.
Screening calendar
Skin gets a check every 6 months from age 3: ear tips, nose bridge and belly are where sun damage starts. Any sore that has not healed in 3 weeks, any cyst that grows past 1 cm, reddens, or drains, and any sudden patch of hair loss with crusting needs a visit, not another bath.
Hypertrophic cardiomyopathy (HCM) is reported in the breed's small gene pool, so a first echocardiogram at 12 months is sensible and breeding cats should be screened. Dental disease is common and easy to miss under a dark mask: check the gum line every 2 weeks and book a dental exam annually from age 2. Nails every 2-3 weeks — the nail beds collect brown waxy sebum, and a soft toothbrush with warm water cleans them better than a cotton bud.
Five care mistakes
- Treating it like a Sphynx and bathing weekly. The skin over-produces oil and the coat looks worse.
- Squeezing cysts. It converts a cosmetic lump into an infected one.
- Letting it sunbathe on a windowsill in July. Pale skin burns through glass.
- Running the house at 18 C. This cat has no insulation and will stop moving to conserve heat.
- Skipping the weekly check because the cat hates being handled. Two minutes with a torch beats a surgery later.
When to call the vet
A cyst that is hot, painful, larger than 1 cm or leaking pus; a sore that has not healed in 3 weeks; skin that smells yeasty or looks wet and red; refusing food for 24 hours; a resting respiratory rate above 30 a minute; or any shivering that continues in a room above 22 C. Photograph any lesion weekly with a coin beside it for scale.
Frequently asked
How often should a Lykoi be bathed?
Every 4-6 weeks with a degreasing shampoo, plus a weekly wipe-down with a warm damp cloth and spot cleaning of the chin and tail base twice a week. Weekly bathing is counterproductive because it strips the skin, which then produces more oil. Always dry the cat completely and keep it warm afterward, since a damp Lykoi chills quickly.
Are the black lumps on my Lykoi dangerous?
Most are follicular cysts and are cosmetic. A small one often settles with 5 minutes of warm compresses twice a day for a week. See a vet if a cyst grows past 1 cm, becomes hot or painful, drains pus, or if a crusty sore on exposed skin has not healed in 3 weeks, because sun-damaged skin in this breed can develop squamous cell carcinoma.
Can a Lykoi live in a cold house?
It can survive but not thrive. With no undercoat it has very little insulation, so keep the living area at 21-24 C, provide a heated bed, and add a sweater below 20 C. Signs of cold stress are shivering, a hunched posture with tucked feet, and abandoning play to sit against a radiator.
