Lambkin: Breed Guide, Two Traits, Care, Health Debate & Best Names
The Lambkin is the cat that looks back at you like a lamb: a tiny-to-small, low-slung cat in a plush, curly coat, built by crossing the short-legged Munchkin with the curly-coated Selkirk Rex. In our cat breed library it is one of the rarest entries, a deliberate designer cross the major registries have never taken beyond the margins. Admirers see a sweet, dog-like companion in a fleece. Critics see the dwarf-cat welfare debate wearing curls. Both are covered here, with contested claims attributed.
What the sources agree on is the animal itself: an affectionate, playful, people-first indoor cat that follows its household around, keeps a kitten’s curiosity for life, and asks for two specific kinds of care, a gentle hand on a coat whose curl is easy to ruin,
History: Terri Harris and the Little Lamb
📖 Breed History
The Lambkin was developed in the United States by breeder Terri Harris, who was already working with dwarf cats: her Munchkin and American Curl cross produced the Kinkalow in the same period. For the Lambkin she crossed the Munchkin with the Selkirk Rex, aiming to put the Selkirk’s plush curly coat on the Munchkin’s short legs. No source documents a single founding year: the work is placed in the late 1980s and early 1990s, with Catster giving the window as sometime between 1987 and 1991. The name is the coat: a Lambkin’s soft curls look and feel like a young lamb’s fleece, and “lambkin” itself means a little lamb. It is also recorded as the Nanus Rex, from the Latin nanus, dwarf.
Recognition never followed. The small Rare and Exotic Feline Registry (REFR) recognizes the Lambkin, and it was formerly recorded by the Designer Cat Association, also called the Dwarf Cat Association, which is now defunct. Neither the Cat Fanciers’ Association (CFA) nor The International Cat Association (TICA) has ever granted it championship recognition, no major registry publishes a standard for it, and its status is experimental or developing at most. Some secondary guides blur this into “recognized by TICA”; the stronger sources do not support that. Why institutions keep dwarf crosses at arm’s length is the subject of the welfare section below.
Two Traits in One Cat
A Lambkin does not blend its parents into an average. It inherits two separate dominant traits, one from each side, and they assort independently in every litter. That explains almost everything about this breed, including why it is so rare.
From the Munchkin come the legs: a single autosomal dominant gene, a form of chondrodysplasia that shortens the long bones while body, head and spine grow to normal size. A Lambkin is not a miniature cat but a normal-bodied cat carried low, hind legs often slightly longer than the front.
From the Selkirk Rex comes the curl: a separate autosomal dominant gene, a splice variant in the keratin gene KRT71, and a different mutation from the recessive rex genes behind the Cornish Rex and the Devon Rex. One copy is enough for the curl, and only one curly parent is needed.
Because legs and coat are inherited separately, one litter can deal out all four combinations: short-legged and curly kittens, the Lambkin proper; short-legged kittens with straight coats; long-legged kittens with curly coats; and kittens with neither trait. The DK Cat Encyclopedia lists exactly these four outcomes. That arithmetic, not a lack of interest, is why so few true Lambkins exist.
One breeding rule is absolute: two short-legged cats are never bred together. A kitten inheriting the dwarf gene from both parents is not viable and does not survive to be born, the same embryonic lethality documented in the Munchkin. Responsible breeding therefore pairs a short-legged cat with a normal-legged one.
Appearance: A Normal Cat, Carried Low, in a Fleece
The outline is unmistakable: a body long in relation to its legs, a broad, rounded, full chest, and a stance close to the ground. The head is wedge-shaped to rounded with full cheeks; the eyes are large, round and set well apart, in any colour. The tail surprises first-time viewers: long, often curved and fluffy, tapering to a rounded tip, on a cat whose legs are a fraction of the usual length.
The coat is the signature: plush, dense and soft, in loose curls and waves rather than tight ringlets, the wave clearest on the belly, neck and tail. It comes in short and long lengths, and in all colours and patterns: solids, tabby, tortoiseshell, bicolour and pointed all occur. The whiskers are part of the rex package: curly and fragile, prone to breaking off short, which is normal here rather than a sign of illness.
No formal breed standard sets a Lambkin weight range, because no major registry judges the breed. The pet-guide consensus puts adults at about 4 to 9 pounds, with several references at 5 to 9, and a shoulder height around 7 to 8 inches: one of the smallest cats in this library, small because of the legs, not the body.
Temperament & Personality: The Rex’s Docility, the Munchkin’s Impishness
The DK Cat Encyclopedia sums the blend up neatly: the Lambkin is reputed to have the docility of the Rex with a touch of the Munchkin’s impishness. Guide after guide describes the same cat: sweet, gentle, calm and tolerant, affectionate to the point of following people room to room in a dog-like way, claiming laps, and staying playful and kitten-curious well into adulthood. Most are quiet to moderately talkative.
They are generally good with respectful children and other pets, and suit homes where someone is around: sources say this breed bonds hard, dislikes long stretches home alone, and can turn destructive when bored. One caution from Catster is worth repeating: boisterous large dogs are a genuine injury risk to a tiny, short-legged cat that cannot leap out of trouble, even when the dog means well.
An honesty note: so few Lambkins exist that this picture rests on owner and breeder reports and the parent breeds’ reputations, not on any formal study. Individual cats vary, but the reports agree with each other to an unusual degree.
Care: Protect the Curl, Then Arrange the Room
Coat care, the rex rules. The curl is maintained by restraint, not effort. Run a wide-tooth comb gently through the coat once or twice a week to lift loose hair and stop tangles at the roots; longer coats may need it a little more often. Do not over-brush: heavy brushing snaps the curl, leaves frizz, and can pull the wave straight out. Bathe only occasionally and let the coat air-dry. Check ears weekly, trim claws regularly, and handle the face gently: those curly whiskers are brittle. Our fluffy cat names readers meet this trade-off often: a glorious coat that punishes rough grooming.
Legs, weight and the shape of the home. Keep the cat lean: extra weight loads shortened limbs and the spine, so feed measured meals rather than free-feeding. Make height optional instead of athletic: steps or a ramp to the sofa and bed, a low-sided litter box, low scratching posts and shorter cat trees, so the cat reaches everything without repeated jumps down from full height, the landing that stresses short legs most. Play at floor level, keep the cat indoors, and cover the household basics with our new cat owner starter kit, adding steps and a wide-tooth comb from day one.
Health & the Welfare Debate
The Lambkin stacks two mutation-based breeds, and credentialed people disagree about whether breeding dwarf cats is acceptable at all. Here is the honest map, each side attributed.
The inherited watchlist. From the dwarf side, veterinary and breed references record increased incidence in Munchkin-type cats of lordosis (an exaggerated inward curve of the lower spine, mild in most cases, organ-compressing in severe ones) and pectus excavatum (a sunken breastbone that can affect breathing in serious cases), plus joint strain and osteoarthritis risk in shortened limbs and dental disease including gingivitis. Obesity aggravates everything on the leg side. From the Selkirk side, the breed is generally described as robust, with one standing watch: polycystic kidney disease (PKD), seen in some Selkirk Rex lines because Persians were used to build that breed. PKD has a well-established DNA test, so a responsible breeder can show tested, clear parents; Selkirk references also flag a heart-muscle (HCM) watch from the British Shorthair side of that breed’s ancestry. None of this means an individual Lambkin will be unwell; screening and monitoring are part of this breed’s contract.
The case made by supporters. Breeders and owners point out that the dwarf gene in single copy produces cats that run, climb and play without obvious impairment, and that TICA fully recognizes the Munchkin itself. Researchers who study the gene note that this dwarfism most closely resembles human hypochondroplasia and, in that assessment, carries no noted health concerns beyond the limbs themselves. On this view, the response is screening and careful pairing, not prohibition.
The case made by critics. Welfare bodies answer that a trait need not disable every cat to be a welfare problem. UFAW’s genetic-welfare work concludes that shortened limbs carry a higher risk of severe osteoarthritis and restrict normal behaviour. International Cat Care has voiced concerns about designer cats built on defective genes. FIFe prohibits breeds based on dwarfism, names the Munchkin pattern as unacceptable manipulation of “genetic disease,” and bars dwarf cats from its shows. Britain’s GCCF refuses dwarf breeds and will not recognize a breed whose key feature is a structural anomaly such as shortened limbs. The German expert database QUEN classifies disproportionate dwarfism under the §11b “torture breeding” (Qualzucht) framework, and Munchkin breeding is restricted in the Netherlands and parts of Australia.
Practical guidance, whichever side you land on. Ask any breeder which pairing produced the litter and walk away from any dwarf-to-dwarf mating. Ask for PKD DNA results for the Selkirk side, and for the health of related adult cats. Keep the cat lean, keep a vet who knows dwarf and rex cats, and watch mobility: stiffness after rest, reluctance to jump, or a changed gait deserves a visit. Consider rescue too: an adult whose health is known is, for many people, the most defensible way to live with one.
Living With a Lambkin
Day to day, a Lambkin household is floor-level and close: a small curly cat trotting after you, a lap claimed whenever one forms, play at rug height, and a weekly comb-through that doubles as bonding time. The fit is specific: people home a lot, gentle children who understand a small, short-legged cat is handled and never wrestled, and a home arranged with steps and low perches. Other cats and calm, cat-savvy dogs are usually a plus. Long empty workdays or wanting an independent pet argue against this breed.

Frequently Asked Questions
Is breeding Lambkins ethical?
It is genuinely contested, and the contest is really about the dwarf gene. Supporters argue that single-copy dwarf cats live active lives, that TICA fully recognizes the Munchkin parent, and that screening plus never breeding dwarf to dwarf manages the real risks. Critics, including FIFe, the GCCF and welfare scientists at bodies such as UFAW, argue that shortened limbs carry a higher risk of severe osteoarthritis and restrict normal behaviour; Germany’s expert assessment places disproportionate dwarfism under its “torture breeding” framework, and Munchkin breeding is restricted in the Netherlands and parts of Australia. Our summary: the cats are widely reported to be affectionate and active, the institutional verdict on the dwarf side is mostly negative, and the practical middle ground is screening, transparency about pairings, and considering rescue.
Why can’t two short-legged Lambkins be bred together?
Because the short-leg gene is dominant and lethal in double dose: a kitten inheriting it from both parents does not survive to be born. Responsible breeding always pairs a short-legged cat with a normal-legged one, which is also why litters are mixed: roughly half the kittens inherit the single copy that shortens the legs, and the coat gene deals itself out separately.
Why do Lambkin litters look so different from kitten to kitten?
Because the two signature traits are two separate dominant genes, not one package. Legs come from the Munchkin gene, curl from the Selkirk Rex gene, and each kitten inherits them independently. One litter can hold all four combinations; only the short-legged, curly kittens are Lambkins to type, which is the main reason the breed stays so rare.
Is the Lambkin a recognized breed?
Only in a limited sense. The Rare and Exotic Feline Registry recognizes it, and it was formerly recorded by the now-defunct Designer Cat Association, also called the Dwarf Cat Association. Neither the CFA nor TICA has granted it championship recognition, and no major registry publishes a standard for it. If a companion is the goal, the health screening in the welfare section matters more than any registry’s stamp.
How long do Lambkin cats live?
Published guides converge on 12 to 15 years, and this profile uses that range, but honestly: the breed is too rare and too young for survival data of its own. As Creatures’ breed reference puts it, there is no breed-specific figure; 12 to 15 years is the general healthy domestic-cat expectation, borrowed from the parent breeds. No source can promise a number.
How do I groom a Lambkin without ruining the curl?
Gently, and less than you might expect. Comb once or twice a week with a wide-tooth comb, working down to the roots to stop mats before they tighten. Skip heavy brushing: it snaps the curl and leaves frizz. Bathe only occasionally and let the coat air-dry. A kitten’s coat will confuse you once, losing its curl at around four months before the adult curl grows in from about 8 to 10 months; that is the normal Selkirk pattern, not a grooming failure.
