American Curl

The American Curl is a medium-sized domestic cat, and it is best known for a single feature: ears that curve backwards away from the face and towards the centre of the back of the skull. Its kittens are born with straight ears, and the curl takes shape over the first few days to weeks of life. The breed comes from the United States, and it stays close to its people for the whole of its life.

An adult usually weighs somewhere between 5 and 10 pounds. The breed exists in both longhair and shorthair forms, and in each the coat lies flat with very little undercoat, so grooming stays undemanding. Temperament is the breed's other calling card. American Curls are affectionate, playful and good-natured, and they will follow their owners from room to room rather than keep to themselves.

Since the curl comes from a single dominant gene, a cat needs only one curled-ear parent to inherit the trait. Breeders grade how far the curl goes, and a pet-quality cat may carry a gentler arc than a show cat. The ear cartilage is firm, but it should be handled gently so as not to cause injury.

Who it suits

The American Curl suits a household that wants an interactive cat and can give it attention each day. It gets on with children and other animals, and it takes to apartments and houses alike. Anyone who travels a lot or is out for long hours should arrange company or enrichment, as this breed does not take well to long stretches on its own.

The breed started with a stray. In June 1981 a black longhaired kitten with unusual curled-back ears turned up at the Lakewood, California home of Joe and Grace Ruga. They named her Shulamith, and she is the foundation cat behind every American Curl since.

A later litter from Shulamith made the point about heredity plain: two of her kittens carried the same curled ears. Geneticists who looked into the line found that the curl comes from a single autosomal dominant gene, so one copy on its own produces the ear shape.

Through the 1980s breeders and cat fanciers worked to set a breed standard. The American Curl was accepted for registration and then advanced through the show classes of the major North American registries, reaching championship status before the decade ended. Both the longhair and shorthair varieties were developed.

While the breed was being established, outcrossing to non-pedigree domestic cats was allowed, which kept the gene pool broad and supported general hardiness. Against older established cats the American Curl is still relatively uncommon, though it is now bred in several countries, Ireland's cat fancy among the places where enthusiasts keep the breed.

Beyond the ears, the American Curl has a moderate, balanced build with nothing extreme about it. The body is medium in length and size, the head is a modified wedge, and the eyes are walnut-shaped. The ear is what defines the breed: it sits wide and high and curves backwards in a smooth arc. A correct ear is firm at the base, and its tip points towards the centre of the back of the head.

Coat and colours

Both coat lengths feel silky and lie close to the body, as there is little undercoat. The longhair variety carries a plumed tail and a soft ruff, and the shorthair is sleeker overall. Registries accept the full range of colours and patterns, solid, tabby, tortoiseshell, bicolour and pointed included. The degree of ear curl is graded from a slight arc to a tighter crescent, and a show cat is expected to display a pronounced but smooth curl with no creasing of the cartilage.

The American Curl is an affectionate, people-oriented cat. It seeks out human company, will often meet its owners at the door, and stays near the family rather than slipping away. Many hold on to a playful, kitten-like curiosity into their senior years, and the breed has picked up an informal name as the cat that never quite grows up.

With children the breed is patient and tolerant, provided it is handled gently and its ears are left alone. It usually accepts other cats and cat-friendly dogs, above all when the introductions are gradual. Towards strangers the American Curl is generally sociable rather than shy, though individual cats differ.

This is not a loud breed. American Curls talk in quiet trills and chirps far more than in insistent meowing. They are intelligent and take pleasure in interactive play, puzzle feeders and small tricks. Their strong bond with people means they do best with company and can grow unhappy if left alone for long stretches.

The American Curl is straightforward to care for. Because the flat-lying coat has little undercoat, it resists matting, and grooming stays light for both coat lengths. The one thing that needs particular care is the ears, which hold firm cartilage that can be hurt if it is bent or twisted.

Grooming

• Brush the shorthair weekly and the longhair two to three times a week to remove loose hair.
• Clean the ears gently with a vet-approved solution and check for wax or debris; never force or bend the cartilage.
• Trim the nails every two to three weeks.
• Brush the teeth several times a week to limit dental disease.
• Bathe only now and again, when the coat is dirty.

Exercise

• Give 20 to 30 minutes of interactive play daily with wand toys or chase toys.
• Provide climbing trees and perches so the breed can use up its energy.
• Rotate puzzle feeders and small toys to keep the cat engaged.
• Arrange attention and play around the times the cat would otherwise be alone.

Environment

The American Curl takes to apartments and houses alike. It is an indoor-suited companion that wants to be part of household life. Give it vertical space, a quiet place to rest, and human or animal company through the day. A second pet can help when owners are out for long stretches.

Cats are obligate carnivores, so the American Curl needs a complete and balanced diet built around animal protein. Pick a food that meets a recognised nutritional standard for the cat's life stage. Fresh water should always be available, and wet food helps with hydration. Portion control matters, because a medium cat that overeats can drift towards obesity.

Treats and supplements

Treats should make up no more than about 10 percent of daily calories. A cat on a complete commercial diet rarely needs supplements; add them only on veterinary advice. Check body condition every few weeks and adjust portions if the cat gains or loses weight.

The American Curl is regarded as a generally healthy and hardy breed, helped by the outcrossing to domestic cats during its development, which kept the gene pool broad. Typical lifespan is 12 to 16 years with good care. No genetic disease unique to the breed is widely documented, but the ear shape and ordinary feline health needs deserve attention.

Preventive care

• Book an annual veterinary exam, and twice yearly for senior cats.
• Keep core vaccinations and parasite prevention up to date.
• Clean and inspect the ears on a regular schedule.
• Keep up dental care at home and have the teeth checked at exams.
• Track weight and body condition to catch gradual changes.

The American Curl is intelligent and eager to interact, so it takes well to training built on rewards. The breed's attachment to people works in the owner's favour, since the cat is motivated by attention as much as by food. Many learn to come when called, fetch, walk on a harness or perform simple tricks. Keep the sessions short and end on a success.

Basics

1. Settle litter habits early with a clean, accessible tray and consistent placement.
2. Redirect scratching to posts and pads, and reward the cat for using them.
3. Teach name recognition and recall by pairing the name with a treat.
4. Introduce a harness and lead gradually if outdoor walks are the goal.
5. Add tricks such as sit or high-five once the cat responds reliably to rewards.

Cats reach sexual maturity at roughly 5 to 10 months, though responsible breeders wait until a cat is physically mature before breeding. A single autosomal dominant gene governs the curled-ear trait, so a kitten needs only one curled-ear parent to inherit curled ears. Breeders often pair a curled cat with a straight-eared cat or another Curl, and a litter can include both curled and straight-eared kittens.

Gestation lasts about 63 to 65 days. All kittens are born with straight ears. Within the first several days the ears begin to curl, tightening over the following weeks before settling into their adult set by around four months. Breeders grade the final curl to sort show prospects from pet-quality kittens.

Queens raise their litters with normal maternal care. Kittens nurse for several weeks, begin weaning around four weeks, and are usually ready for new homes at 12 weeks or older, after early socialisation and first vaccinations. Outcrossing to domestic cats has historically been allowed to maintain genetic diversity.

Registering an American Curl in Ireland

An ISPCA branch or a vet scanning a found American Curl gets exactly as far as her record allows. Give the scan somewhere to land: a free profile with your name, your number, and her photo. Register your cat once and it holds for good.

The fifteen digits on your American Curl's vet paperwork want a registry. United Pet Club lodges them free, keeps them current through every move, and leaves the record findable whenever a scanner asks. Microchip registration plus a free account: both sorted in one cup of tea.
