Lambkin
The Lambkin — also called the Nanus Rex — is one of the world's rarest dwarf cat breeds, combining the Munchkin's short legs with the Selkirk Rex's dense curly coat into a small, soft, lamb-like cat of exceptional gentleness and warmth.
If someone set out to engineer the maximum achievable softness in a domestic cat — not just in coat texture but in overall temperament, physical feel, and visual impression — they might arrive, through deliberate effort, at something very close to the Lambkin. This small, curly-coated, short-legged cat combines two of the most texturally distinctive features in the cat world: the Munchkin’s achondroplasia-like abbreviated limbs and the Selkirk Rex’s dense, wool-like curly coat. The result is a cat that looks and feels like a small lamb — plush, rounded, low to the ground, and wrapped in a coat so soft that people instinctively reach to touch it. Whether or not one approves of the deliberate combination of two structural mutations, the Lambkin’s temperament — which is one of the gentlest and most consistently affectionate in the domestic cat world — makes a compelling argument that the result of this particular combination is, whatever else it may be, a remarkably good companion animal.
1. History and Origins: Combining Two Curls
The Lambkin is a very recent and deliberately created breed, one of the rarest in the world, produced by crossing the two breeds that define its appearance.
Terri Harris
The Lambkin was developed in the early 1990s by American breeder Terri Harris, who crossed Munchkin cats — carrying the dominant short-leg mutation — with Selkirk Rex cats — carrying the dominant curly-coat mutation. The goal was to produce a cat that combined both mutations in a single animal: short-legged like the Munchkin, curly-coated like the Selkirk Rex.
Because both the Munchkin’s leg mutation and the Selkirk Rex’s coat mutation are dominant, every kitten that inherits either gene will express the trait. A Munchkin × Selkirk Rex cross produces kittens that may be short-legged only, curly-coated only, both short-legged and curly-coated (the true Lambkin), or neither (standard domestic proportions and straight coat, from kittens that received neither dominant gene). Only the kittens carrying both mutations are registered as Lambkin.
The Name
The name “Lambkin” — an archaic English diminutive for a lamb — refers to both the cat’s small size and the lamb-like quality of its dense, curly, plush coat. The alternative name “Nanus Rex” — from the Latin nanus (dwarf) and rex (king, as used in Rex coat mutations) — is more formal but less widely used.
Recognition
The Lambkin is recognized by TICA in experimental new breed status. It remains one of the rarest recognized breeds in the world, with very small breeding populations and limited availability even in North America.
2. Appearance: The Small Lamb
The Lambkin’s appearance is immediately distinctive and consistently described in the same terms: a small, round, incredibly soft-looking cat that resembles nothing so much as a tiny plush toy — or a lamb.
The Curly Coat
The Selkirk Rex component gives the Lambkin a coat of dense, loosely curled to tightly curled texture that is dramatically different from any straight-coated breed. The Lambkin comes in both shorthaired and longhaired varieties, both with the characteristic Selkirk curl.
In the shorthaired Lambkin, the coat is dense, plush, and curly in a way that recalls a Persian’s density but with movement and texture. In the longhaired Lambkin, the curls are more clearly defined and longer, creating flowing ringlets and swirls of remarkable visual interest. The whiskers and eyebrows are also typically curled.
The coat accepts all colors and patterns — the same range as the Selkirk Rex — and the combination of color and curl creates an effect that is genuinely beautiful in well-marked individuals.
The Short Legs
The Munchkin-derived short legs give the Lambkin its characteristic low-slung, close-to-the-ground profile. The legs are noticeably shorter than standard domestic cat proportions, but the Lambkin is not immobile or limited — it runs, jumps, and plays with the same enthusiasm as a standard-proportioned cat, simply doing so from a lower vantage point.
The Body
The body is compact, rounded, and well-muscled for its size. The chest is broad, the neck is short and substantial, and the tail is medium-length with curled fur. Males typically weigh 4 to 9 pounds; females 4 to 7 pounds. The combination of compact body, short legs, and curly coat creates an impression of roundness and softness that is one of the breed’s most immediately charming qualities.
The Face
The head is moderate and round, with a short muzzle and large, round eyes that can be any color. The curled whiskers — a Selkirk Rex characteristic — add to the breed’s lamb-like impression.
3. Personality: Gentle and Warm
The Lambkin’s personality reflects the best qualities of both its parent breeds, combining the Munchkin’s playful, people-oriented sociability with the Selkirk Rex’s patient, gentle, calm temperament.
Exceptionally Gentle
The Lambkin is among the most consistently gentle domestic cat breeds. It handles physical interaction with great patience, tolerates children’s attention with a softness and tolerance that is unusual even among gentle breeds, and does not react aggressively to frustrating situations. The temperament is soft-edged throughout.
Affectionate and Lap-Oriented
The Lambkin is a genuine lap cat — a designation that is overused in cat descriptions but genuinely accurate here. It seeks out physical warmth and human contact with consistent enthusiasm and is happy to remain settled in a lap for extended periods, particularly when the coat is being stroked. This affectionate quality, combined with the extraordinary tactile pleasure of its curly coat, makes the Lambkin an unusually satisfying cat to simply sit with.
Playful but Calm
The Lambkin is playful — it engages with toys and interactive games with genuine enthusiasm — but its energy level is moderate rather than high. It does not have the restless, driving energy of a Bengal or Abyssinian; it plays in focused, enjoyable sessions and then settles into comfortable companionship without restlessness.
Social with Everyone
The Lambkin is broadly social — good with children, other cats, and dogs. Its gentle, non-territorial temperament means it integrates well into multi-pet households and handles family activity with equanimity.
Indoor Preference
The Lambkin’s combination of short legs and dense curly coat make it both less agile outdoors and more vulnerable to weather conditions than most breeds. It is fundamentally an indoor cat, and its temperament is well-suited to indoor living — it does not have the restless, outdoor-seeking drive of some more independent breeds.
4. Care and Maintenance
Coat Care
The curly coat requires careful, regular grooming. The Selkirk Rex component means the coat is prone to tangling if neglected, particularly in the longhaired variety. Two to three weekly combing sessions with a wide-tooth comb are necessary to prevent mat formation, particularly behind the ears, in the armpits, and on the belly. The coat should be combed rather than brushed — a slicker brush can disrupt the curl pattern and stretch the coat.
Bathing every four to six weeks maintains coat health and curl definition. The Lambkin’s coat responds well to being air-dried after bathing — towel drying can disturb the curl pattern, while air drying allows the curls to reform naturally.
Warmth
The Lambkin’s dense coat provides more insulation than it might appear, but the small body size and limited activity level mean it benefits from warm sleeping spots.
Health Monitoring
The combination of two structural mutations — short legs and curly coat — means that the Lambkin’s health should be monitored by a veterinarian familiar with both Munchkin and Selkirk Rex health concerns.
5. Health and Lifespan
The Lambkin has a lifespan estimated at 12 to 14 years, based on the lifespans of its parent breeds. As an extremely rare breed with a small population, formal long-term health data is limited.
Joint and Spinal Health
The Munchkin’s short-leg mutation raises ongoing questions about joint and spinal health that apply equally to the Lambkin. Maintaining a healthy body weight — particularly important for a short-legged cat — minimizes joint stress. Veterinary monitoring for any signs of joint discomfort or mobility changes is recommended.
Hypertrophic Cardiomyopathy
HCM is a potential concern in both parent breeds. Annual cardiac screening for breeding animals is recommended.
Ethical Considerations
The Lambkin, combining two structural mutations in a single animal, sits at the center of ongoing ethical debates in the cat fancy about the deliberate creation of cats with multiple physical modifications. Prospective owners should research these debates thoroughly and make informed decisions.
6. Is a Lambkin Right for You?
Ideal for:
- Those who want an exceptionally gentle, soft, and affectionate lap companion
- Indoor-oriented households where the Lambkin’s preference for indoor living is met
- Families with older children who can appreciate the breed’s specific gentleness
- People drawn to the combination of curly coat and compact body aesthetics
Less ideal for:
- Those uncomfortable with the ethical debates around multiple-mutation breeds
- Very active households where the Lambkin’s moderate energy might not keep pace
- People wanting an outdoor or free-roaming cat
Conclusion
The Lambkin is, whatever one’s views on its development, a genuinely remarkable small animal. Its coat is among the softest in the domestic cat world. Its temperament is among the most consistently gentle. It sits in laps with an unhurried willingness that suggests it has thought the situation over and concluded that this is, in fact, exactly where it should be. For the person looking for a quiet, warm, absurdly tactile indoor companion, the Lambkin delivers on every dimension it promises — and the experience of running a hand through that dense, curly coat remains one of the most purely pleasant sensory experiences available in the domestic cat world.
