Coat and looks how to spot one

curly (rex) coat, usually long; short legs

A small, short-legged cat that pairs the Munchkin's low-slung build with the Selkirk Rex's thick, curly coat. The fur is plush and soft, often with loose curls that give the cat a woolly, lamb-like look, and some individuals have a straighter coat.123

Colourswhite (most often seen)blackbluegreysilvercreamgingerbrownfawnvarious patterns23

Personality what they are like

Gentle, calm and very affectionate. Lambkins like to be close to their people, enjoy both cuddles and play, and are happiest in homes where someone is around for much of the day.23

Daily activity how busy a day looks

Moderate. Short legs do not stop it from being agile and inquisitive; regular play and puzzle toys keep it engaged.3

Grooming and care the hands-on bits

Gentle brushing at least once a week, and ideally several times a week, keeps the curls neat and free of tangles.23

Food basics what goes in the bowl

A carnivore diet rich in animal protein and fat; both wet and dry complete foods are suitable.3

Company who they like around

Enjoys the company of people and other cats and does not like being left alone for long.23

The story where it all began

The Lambkin was developed in the United States by crossing the short-legged Munchkin with the curly-coated Selkirk Rex. Breeder Terri Harris is credited with starting the line in the late 1980s or early 1990s. It remains an experimental breed recognised mainly by smaller registries.13

Fun facts for the dinner table

  1. 1

    The name Lambkin comes from the breed's resemblance to a young lamb.2

  2. 2

    Its alternative name Nanus Rex combines the Latin word for dwarf with 'rex', the term for a curly coat.2

  3. 3

    Lambkins are rare partly because litters seldom produce kittens that have both short legs and curly coats.2

  4. 4

    Some owners say Lambkins collect and hide small objects, a little like a magpie.3

Where the name comes from the story behind it

The breed name 'Lambkin' originated as a comparison of their coat to that of a lamb, due to the soft, plush, curly coat inherited from the Selkirk Rex parent.4

A day in the life told by a Lambkin

This morning I woke up on my human's chest, purring like a tiny motor. After a good stretch, I followed them to the kitchen, weaving between their ankles just in case. Then it was playtime with my favorite feather wand, and I did my best bunny kick! Later, I claimed the sunny spot on the windowsill for a long nap, only waking for a gentle chin scratch. When my human came home, I greeted them at the door with a head bump and a happy trill. We spent the evening curled up on the couch, my paws kneading their lap. Life is good when you're this loved.

The care rhythm a typical week and year

A typical home-care rhythm for a Lambkin. A starting point, not a vet's advice.

Treats they will love homemade and simple

Lambkin tip

Lambkins gain weight easily, so use low-calorie treats like freeze-dried meat or a few kibbles from their daily ration. Because they can develop food allergies, introduce any new treat one at a time and watch for itching or tummy upset.
