Cornish Rex vs LaPerm: Wave Coat vs Curl Coat Comparison

Last updated: May 6, 2026

The Cornish Rex and the LaPerm both wear curly coats, but the resemblance ends at the surface. Different genes, different textures, different origin stories, and different body types separate them. Choosing between them is a decision about coat aesthetic — fine velvety waves versus soft loose curls — and about what kind of breeder community and care commitment you prefer.

Quick Comparison

The Cornish Rex carries a recessive r gene that produces a fine, very short, wavy coat lying close to the body in a “marcel wave” pattern. The breed traces back to a single curly-coated kitten born in Cornwall, England, in 1950, with parallel discoveries in Sweden contributing to the gene pool. CFA and TICA both recognize the breed in championship classes.

The LaPerm carries a dominant Lp gene that produces loose, soft curls or waves throughout the coat. The breed originated on Linda and Richard Koehl’s farm in Oregon in 1982, when a curly kitten appeared in a barn-cat litter. The LaPerm comes in both shorthair and longhair varieties. CFA recognizes the breed for championship.

The genes work very differently. Recessive Cornish Rex coat means both parents must carry the gene to produce curly kittens. Dominant LaPerm coat means a single parent carrying the Lp gene can produce curly kittens. This affects breeding management and litter predictability significantly.

Origin and History

The Cornish Rex traces back to a single 1950 kitten named Kallibunker, born in Cornwall to a barn cat named Serena. The kitten’s curly coat was identified as a spontaneous mutation, and breeders developed the line by backcrossing to Serena and outcrossing to Burmese, British Shorthair, and Siamese. A separate parallel discovery of curly-coated cats in Sweden contributed additional foundation genetics. The breed was recognized in the United Kingdom in the 1960s and crossed to North American registries shortly after.

The LaPerm has a much more recent origin. Linda Koehl’s working barn on a fruit orchard in Oregon produced an unexpectedly curly kitten in 1982, named Curly. Linda observed that the curly trait passed to subsequent generations from a single parent, indicating dominant inheritance. She developed the breed program over the next decade, and the LaPerm gained championship recognition with TICA and CFA in the 2000s.

Appearance and Build

The Cornish Rex’s coat is the breed’s defining feature. Very short, very fine, and lying close to the body in a tight wavy pattern that resembles fingerwave hair. The coat lacks the outer guard hairs found on most cats — the visible coat is the soft awn and down layers only. The body is slim, athletic, and high-haunched, with a small egg-shaped head, oversized rounded ears, and large oval eyes. Adult weight runs six to ten pounds, with the slim build making the cat appear smaller than the weight.

The LaPerm’s coat is looser, longer, and softer than the Cornish Rex’s. Curls range from tight to loose ringlets, with longer hair around the neck (a “ruff”) and tail. The coat texture varies through life — kittens are often born straight, lose hair in early weeks, and develop the curly coat as they mature. The body is medium-sized and moderately athletic, with a wedge-shaped head, medium ears, and almond-shaped eyes. Adult weight runs six to ten pounds.

The visual contrast is unmistakable: Cornish Rex coats look like styled human hair lying flat against the body; LaPerm coats look like soft tousled curls standing slightly away from the body.

Temperament and Personality

Cornish Rex cats are known for being highly active, playful, and people-focused. The breed retains kitten-like energy well into adulthood. Many Cornish Rex enjoy fetching, climbing to high perches, and supervising every household activity from a shoulder or windowsill. They are curious, intelligent, and often vocal in a chatty conversational register.

LaPerms have a similarly affectionate but slightly less hyper temperament. The breed bonds strongly with family members and tolerates handling well. LaPerms tend to be quieter than Cornish Rex but still actively seek human interaction. The barn-cat origin means the breed retains some natural hunting instinct and athletic capability.

Both breeds are highly affectionate. Both appear in lists of most affectionate cat breeds. Neither is a low-stimulation lap cat in the Persian or Ragdoll sense.

Care, Grooming, and Activity Needs

Counterintuitively, the curly-coat breeds are not high-maintenance for grooming. Both breeds shed less than fully-coated breeds and are sometimes recommended cautiously for allergic households (though neither is truly hypoallergenic — see the hypoallergenic cat breeds roundup for the full discussion).

The Cornish Rex’s fine short coat needs only weekly gentle brushing or hand-stroking. Aggressive brushing can damage the delicate coat. Some owners bathe occasionally to manage skin oil; others find this unnecessary. The breed loses body heat faster than coated cats because the coat is so thin, so warm bedding and stable indoor temperatures matter.

The LaPerm’s longer coat tolerates more conventional grooming. Weekly brushing or combing keeps the curls defined and prevents tangles, with extra attention for the longhair variety. The coat naturally air-dries with curls intact after bathing. Seasonal shedding is mild compared to fully-coated breeds.

Activity needs are substantial for both. Both benefit from puzzle feeders, climbing structures, and daily interactive play. Indoor enrichment matters for both because both are intelligent and easily bored.

Health and Lifespan

Both breeds are generally healthy compared to many heavily-bred pedigreed cats. Neither carries widespread breed-specific genetic disorders at concerning rates.

The Cornish Rex can be prone to hypertrophic cardiomyopathy, and responsible breeders screen breeding cats. The breed’s low body fat and thin coat mean it loses heat faster than coated cats, so cold-weather precautions matter. Skin conditions can occur but are not widespread.

The LaPerm is a relatively new breed with a young gene pool. The barn-cat foundation contributed genetic diversity that has helped the breed avoid concentrated genetic disorders. HCM screening is recommended. Adopters should ask any breeder for parental health documentation and outcrossing practices.

Both breeds typically live well into their teens with appropriate care. The standard adult wellness checklist covers ongoing monitoring, and chronic kidney disease remains the most common concern for older cats.

Living Situation Fit

Both breeds suit indoor-only homes with engaged owners. Apartments work well for both, especially with vertical space and play opportunities.

The Cornish Rex’s high energy makes it best for households with time for daily play and at least some attentive presence. The breed dislikes being left alone for long workdays without companionship. A second cat or a reliable human routine helps.

The LaPerm tolerates quieter households and is slightly more flexible about alone time. It still prefers companionship but is less prone to attention-seeking destruction than the Cornish Rex.

Multi-pet households work for both with proper introductions — see our cat introduction guide. Both tolerate respectful children well and integrate readily with other cats and friendly dogs.

Cost and Availability

The Cornish Rex has wider breeder availability than the LaPerm because of its longer formal history and active CFA breed club. Kitten prices vary by lineage, color, and breeder reputation. Rescue Cornish Rex appear occasionally through breed-specific networks.

The LaPerm is rarer, with breeders concentrated in the United States and a smaller number of international programs. Waitlists are normal. Both shorthair and longhair varieties are available, with longhair commanding slightly higher prices in some lines.

Lifetime costs are moderate for both. Standard food, routine veterinary care, modest grooming supplies. Plan for first-year ownership costs and an emergency veterinary fund. Neither breed has unusual ongoing costs beyond standard pedigreed-cat care.

Decision Framework: When to Choose Each

Choose a Cornish Rex if: you want a fine velvety wavy coat lying close to the body, a highly active playful cat with kitten-like energy into adulthood, and a breed with broad established breeder availability. The Cornish Rex is the more intense personality between the two and rewards owners who want a constantly engaged cat. For comparison with its closest relative see Devon Rex vs Cornish Rex and the Devon Rex profile.

Choose a LaPerm if: you want soft loose curls with a more substantial coat, the option of shorthair or longhair, and a slightly calmer overall temperament. The LaPerm fits households that want a curly-coat breed with somewhat more flexibility around alone time and visitor traffic.

Frequently Asked Questions

Are these breeds hypoallergenic?

Neither is truly hypoallergenic. Both shed less than fully-coated breeds and may be tolerated better by some allergic people, but they still produce the Fel d 1 protein that triggers most cat allergies. Spend time with the breed before adopting if you have known allergies. The hypoallergenic cat breeds roundup covers the broader topic.

Why does the LaPerm coat change over time?

LaPerm kittens often go through a coat-change cycle: they may be born straight-coated, lose much of their hair within the first few weeks, and grow back curly as they mature. This is normal for the breed and reflects the dominant Lp gene’s expression pattern. Adult coats stabilize after the first year or two.

Does the Cornish Rex’s thin coat mean it’s always cold?

The breed loses body heat faster than fully-coated cats because the coat is very thin and lacks guard hairs. In cold homes the cat may seek out warm spots — laps, sunbeams, heated bedding. Indoor temperatures should stay reasonably warm, especially during winter. The breed is not as heat-sensitive as truly hairless cats but warmer than typical cats.

Can I keep just the curls of a LaPerm without trimming?

Yes. The LaPerm coat is meant to look natural and tousled. Trimming or styling the coat is generally discouraged in show cats, and most pet owners simply brush gently and let the curls define themselves. The coat air-dries naturally with curls intact after bathing.

Where can I find a Cornish Rex or LaPerm to adopt?

Both occasionally appear in breed-specific rescue. Start at our adopt-a-cat hub and search for regional Cornish Rex or LaPerm rescue networks. Use the red flags guide when evaluating any breeder.
