American Curl

As is often the case with unique breeds, the American Curl’s story began by chance. In June 1981, a couple named Joe and Grace Ruga noticed two stray kittens on their doorstep in Lakewood, California. Both had long, silky black coats and an unusual feature: their ears were curled backward. Sadly, one kitten disappeared, but the other, named Shulamith, stayed with the Rugas and became the founding mother of all American Curls in the world.

When Shulamith gave birth to her first litter in December 1981, two of the four kittens had the same curled ears. This confirmed that the unique trait was a dominant genetic mutation. This means that only one parent needs to carry the gene for curled ears to be passed on to their kittens. Unlike some other ear-folding mutations, like the one found in Scottish Folds, the Curl’s gene isn’t linked to any skeletal deformities or other serious health issues.

Enthralled by their cat’s unique look and charming personality, the Rugas began a dedicated breeding program. By 1983, American Curls were showcased for the first time at a cat show in California, where they immediately caught the attention of cat fanciers and experts. Breeders and geneticists, including renowned British expert Roy Robinson, studied over 380 Curl kittens and confirmed the absence of any genetic defects related to the ear mutation. For another fascinating breed born from a spontaneous mutation, you might want to look at the American Wirehair, known for its distinct coat texture.

The path to official recognition was a swift one. The International Cat Association (TICA) recognized longhaired American Curls in 1986 and shorthairs in 1991. The Cat Fanciers’ Association (CFA) granted the breed championship status in 1993, uniquely for both longhair and shorthair varieties at the same time. This was a first in CFA history and highlights the breed’s key distinguishing feature is the ear shape, not the coat length.

The American Curl is a medium-sized cat with an elegant yet sturdy, rectangular body. It has well-developed muscles but doesn’t look massive. Balance and proportion are key characteristics of its build.

1. Head: Shaped like a modified wedge, with no flat planes. Its length is slightly greater than its width. The profile has a gentle curve from the forehead to the nose, which is straight and of medium length. The muzzle is rounded with soft transitions.
2. Ears: This is the breed’s defining feature. They are wide at the base, medium in size, and smoothly curl back at an angle of 90 to 180 degrees. The ear tips are rounded and flexible. The cartilage is firm at the base, for about one-third of the ear’s height. It’s crucial that the tips of the ears do not touch the back of the ear or the head. They often have tufts of hair (sometimes called “ear furnishings”), especially in longhaired individuals. Important Note: Kittens are born with straight ears that begin to curl within the first 3-10 days of life and reach their final shape by four months of age. The degree of the curl can vary, and not all kittens in a litter will have a “show quality” curl. Some may have a less pronounced “pet quality” curl or even straight ears.
3. Eyes: Large, expressive, and walnut-shaped—oval on top and round on the bottom. They are set slightly at a slant, on a line from the base of the ear to the tip of the nose. Eye color can be any color and is not dependent on coat color, with the exception of colorpoints, whose eyes are always blue. The gaze is open and friendly.
4. Body: Medium-sized, semi-foreign type, and elegant. The body length is approximately one and a half times the height at the withers. The chest is rounded, and the back is straight. The bone structure is moderate, and the muscles are well-developed but not overly bulky.
5. Legs and Paws: The legs are of medium length, proportionate to the body, and straight. The paws are rounded and of medium size.
6. Tail: Flexible, wide at the base, and tapers to a point. The tail is equal in length to the body. In longhaired Curls, the tail is a beautiful, full plume.
7. Coat: There are two variations: shorthair and longhair.

• Longhair: The coat is fine, silky, and lies close to the body, with minimal undercoat. The tail hair is longer, forming a beautiful plume. A ruff around the neck is desirable.
• Shorthair: The coat is short, soft, silky, and resilient, also with minimal undercoat, lying close to the body.

Both coat types are known for their soft, silky feel to the touch. For more details on similar-looking cats with different genes, check out the Pixie-Bob and Kurilian Bobtail Longhair.

Colors and Patterns: American Curl breed standards accept absolutely all possible colors and patterns, including colorpoint, sepia, mink, bi-colors, tri-colors, all variations of tabby, solid colors, and more. This makes every Curl unique. There are no restrictions on the color of their paw pads or nose leather, other than those that match a specific coat pattern.

The American Curl is often called the “Peter Pan” of the cat world, and this nickname perfectly captures their character. They retain their kitten-like playfulness, curiosity, and energy throughout their lives. These aren’t the kind of cats who will spend all day napping on the couch (though they do love to nap next to their favorite human). Curls are always ready to play, explore new corners of the house, or engage in active fun with people.

Key Traits of the American Curl’s Temperament:

• People-Oriented: This is an incredibly people-loving breed. Curls adore being the center of attention, participating in all household activities, and following their owners from room to room. They don’t do well with long periods of solitude and need daily interaction and affection. If you spend a lot of time away from home, a Curl might become lonely.
• Playfulness: Their energy and desire to play are inexhaustible. They love interactive toys, feather wands, balls, laser pointers (use with caution!), and simply running and jumping. They can even be taught to fetch, which makes them seem almost dog-like.
• Intelligence and Wit: American Curls are smart cats. They quickly learn to open cabinet doors and drawers and can be trained to perform simple commands and tricks, especially when positive reinforcement (treats, praise) is used.
• Gentleness and Affection: Despite their high energy, Curls are very gentle and loving. They enjoy sitting on laps, sleeping next to their owner, and showing their affection with a quiet purr or gentle head bumps. They aren’t pushy but are always happy for contact.
• Sociability: Curls typically get along well with children (assuming gentle handling) and other pets, including dogs and other cats. They are not prone to aggression or dominance; their friendly nature makes them wonderful members of a large family. Their hunting instinct is moderately developed, so they usually don’t pose a great threat to pet rodents or birds (but caution is still needed).
• Adaptability: They adjust easily to new environments, people, and situations, which makes them good travelers if you like to bring your pet along. Some Curls are perfectly happy with walks on a leash.
• Vocalization: American Curls are not an overly “talkative” breed. They make quiet, pleasant sounds, similar to chirping or cooing, when they want attention or express contentment, but they usually don’t bother with loud meows.

Thanks to their friendly, playful, and gentle nature, the American Curl is an excellent companion for active people and families who are ready to dedicate their time and attention to them.

American Curls are generally considered a healthy and hardy breed. Their broad genetic diversity, a result of allowing crosses with domestic cats (both longhaired and shorthaired) during the breed’s development, has helped them avoid many of the hereditary diseases common in other purebreds. The average lifespan of an American Curl is 13-16 years, but with proper care, many individuals live much longer.

However, like any breed, there are certain health aspects to be aware of:

• Ear Canal Issues: While the mutation that causes the curled ears is not associated with any health defects, the unusual shape of the outer ear can potentially lead to a narrowing of the external ear canal in some individuals. This, in turn, can contribute to earwax buildup and increase the risk of ear infections (otitis). Therefore, regular inspection and gentle cleaning of the ears are a crucial part of a Curl’s care routine.
• Common Feline Diseases: American Curls, like all cats, can be susceptible to common feline illnesses. These include:
  • Hypertrophic Cardiomyopathy (HCM): The most common heart disease in cats. Regular cardiac screening is recommended, especially for breeding animals.
  • Polycystic Kidney Disease (PKD): A hereditary disease that primarily affects Persian cats and related breeds, but can also occur in others. Responsible breeders test their cats for the PKD gene.
  • Oral Diseases: Gingivitis, periodontitis, and tartar buildup are common problems that require regular dental care (brushing) and veterinary check-ups.
  • Infectious Diseases: Like all cats, Curls need timely vaccinations against core infectious diseases (panleukopenia, calicivirus, rhinotracheitis, rabies).
• Obesity: Due to their love of food and sometimes insufficient activity (if owners don’t encourage playtime), Curls can be prone to gaining excess weight. It’s important to monitor their diet and ensure they get enough physical exercise.

Prevention is Key to Longevity:

• Regular Vet Check-ups: Annual visits to the vet (or twice a year for senior cats) will help detect potential problems early.
• Vaccinations and Deworming: Sticking to a schedule of vaccinations and parasite prevention is essential.
• Balanced Diet: High-quality food appropriate for your cat’s age and activity level is the foundation of their health.
• Ear and Dental Care: Regular cleaning of the ears and teeth will help prevent infections and diseases.
• Encourage Activity: Providing toys, cat trees, and regular playtime with your cat will help keep them in shape and prevent obesity.
• Choose a Responsible Breeder: When buying a kitten, choose a breeder who tests their breeding cats for common genetic diseases and cares about the health of their kittens.

Overall, the American Curl is a breed with robust health that, with proper care and attention, will bring joy to its owners for many years.

Grooming an American Curl isn’t considered difficult, but it has specific requirements, primarily due to their unique ears and silky coat. Here are the main aspects of their care:

1. Coat Care:

• Coat Type: Curls come in both shorthair and longhair varieties. Both types have a soft, silky texture and a minimal undercoat. This means their fur is less prone to matting compared to many other longhaired breeds.
• Brushing:
  • Longhaired Curls should be brushed 1-2 times per week with a wide-toothed comb or a slicker brush to remove dead hair, prevent tangles, and distribute skin oils throughout the coat. Pay special attention to the “ruff” and “britches,” where the hair is denser.
  • Shorthaired Curls can be brushed just once a week or even less often, mainly to remove dead hair and massage the skin. A rubber brush or a grooming mitt works well for them.
• Bathing: Bathe Curls only when necessary, such as if the cat gets very dirty or before a show. Use a special cat shampoo. Thanks to their minimal undercoat, their fur dries fairly quickly.
• Shedding: Shedding in Curls is moderate and seasonal (in spring and fall). You might need to brush them more often during these periods.

2. Ear Care:

• This is the most important aspect of American Curl grooming. Their curled ears require a regular weekly inspection for dirt, excess wax, or signs of infection (redness, unpleasant odor, discharge).
• Cleaning: Clean the ears as needed using a special feline ear cleaning solution and a cotton pad or soft cloth. Absolutely do not use cotton swabs, as they can damage the eardrum or push dirt deeper into the ear canal.
• Caution: When cleaning or handling a Curl’s ears, you must be extremely careful not to damage the delicate cartilage or cause the cat pain. Do not forcefully bend or pull the ear.

3. Nail Care:

• Trim the tips of their claws regularly (approximately every 2-4 weeks) with special cat nail clippers to prevent them from snagging on furniture and carpets. Only trim the transparent part of the claw, avoiding the pink area (the quick), which contains blood vessels and nerves.
• Having a scratching post (or several of different types) is a must so your cat can satisfy its natural need to sharpen its claws.

4. Dental Care:

• Regular brushing of their teeth with a special feline toothpaste and brush (several times a week, or ideally daily) will help prevent plaque and tartar buildup and the development of gum disease.

5. Eye Care:

• A Curl’s eyes typically don’t require special care. If needed, you can wipe the corners of their eyes with a damp cloth or cotton pad soaked in clean water or a special solution to remove any natural discharge.

6. Litter Box:

• Provide your cat with a clean, appropriately sized litter box with quality litter. The box should be cleaned regularly (solid waste removed daily, and a complete change of litter according to the instructions). Curls are generally tidy and quickly learn to use the litter box.

Following these simple rules will help keep your American Curl healthy, well-groomed, and happy.

Proper nutrition is the foundation of any cat’s health and longevity, and the American Curl is no exception. These active and playful animals need a balanced diet rich in animal-based protein, with a moderate amount of fat and low carbohydrates.

Core Principles of Feeding an American Curl:

• High-Quality Protein: Cats are obligate carnivores, so the basis of their diet should be meat. Choose foods where meat (chicken, turkey, beef, rabbit) or fish is the first ingredient on the list.
• Food Type:
  • Dry Food: Convenient to store and use, and it helps clean teeth of plaque. Choose super-premium or holistic foods that have a balanced composition and high-quality ingredients. Make sure your cat always has access to fresh water, as dry food contains little moisture.
  • Wet Food (Cans, Pouches): Has a high moisture content, which is important for preventing urinary tract diseases. It also has a more appealing aroma and taste for cats. You can combine dry and wet food, serving them at different meal times.
  • Natural Diet: If you choose to feed your cat a natural diet (raw or cooked meat, organs, sometimes vegetables), it’s crucial to carefully balance the diet with all the necessary nutrients, vitamins, and minerals. This requires knowledge and consultation with a veterinary nutritionist to avoid deficiencies or an excess of certain elements. Do not feed your cat food from your table!
• Food Quantity: Follow the food manufacturer’s recommendations on the package, but adjust the portion based on your Curl’s age, weight, activity level, and individual needs. Avoid overfeeding to prevent obesity. It’s best to feed your cat small portions 2-3 times a day.
• Fresh Water: Your cat should always have access to clean, fresh drinking water. Place the water bowl away from the food bowl, and wash it and change the water regularly. Some cats prefer drinking from fountains.
• Treats: Treats can be used for encouragement during training or simply to reward your pet, but they should not make up more than 10% of their daily diet. Choose special cat treats and avoid harmful human foods.
• Forbidden Foods: Never give your cat chocolate, onions, garlic, grapes, raisins, alcohol, caffeine, raw dough, bones (especially cooked chicken bones), fatty and fried foods, or cow’s milk (many adult cats have lactose intolerance).

Special Considerations for Curls:

• Because of their high activity level, Curls may require slightly more calories than less active breeds, but it’s important not to overfeed them.
• Keep an eye on the condition of their coat and skin—a dull coat or dandruff can indicate an unbalanced diet or a lack of certain vitamins (e.g., Omega-3 and Omega-6 fatty acids).

When choosing a diet or if you have any doubts about your American Curl’s nutrition, it’s best to consult with a veterinarian or a pet nutritionist.

American Curls are not only cute and playful but also very smart cats, which makes the process of training and raising them relatively easy and enjoyable. Their natural curiosity, desire to please their owner, and love of games contribute to quick learning.

Training and Learning:

• Positive Reinforcement: Curls respond wonderfully to positive reinforcement-based training methods. Use treats, praise, petting, and games as rewards for good behavior. Avoid punishments and yelling, as this can frighten the cat and break their trust.
• Learning Commands: Thanks to their intelligence, Curls can learn to perform simple commands like “sit,” “come,” “shake,” or even to fetch toys. Clicker training can be a very effective method.
• Leash and Harness Training: Many Curls are comfortable with leash walks, especially if they are introduced to a harness at a young age. This is a great way to provide your cat with safe outdoor adventures and new experiences. Start with short sessions of wearing the harness indoors, gradually increasing the time.
• Correcting Unwanted Behavior: If a Curl is doing something undesirable (e.g., scratching furniture), redirect its attention to a scratching post or a toy. Provide your cat with enough acceptable entertainment so they don’t have to seek it out in forbidden places.
• Puzzle Toys: Use puzzle toys that require your cat to make an effort to get a treat. This stimulates their mind and prevents boredom.

Socialization:

• Early Socialization: It’s very important to start socializing a Curl kitten as early as possible (ideally, with the breeder). Introduce them to different people, sounds, and situations so they grow into a confident and calm cat.
• Introductions to Children and Other Pets: Curls typically get along well with children and other pets. Make introductions gradually and under supervision, especially with dogs. Teach children how to handle the cat properly and gently.
• Environment Adaptation: Help your Curl adapt to your home by creating a safe and stimulating space for them with places to rest, play, and observe (e.g., wall-mounted shelves, access to a window sill).

Remember that the American Curl is a very social animal that needs attention and interaction. Regular play, communication, and training will not only help you raise a well-behaved pet but also strengthen your bond with them.

Like any breed, the American Curl has its advantages and disadvantages. Before getting one, it’s important to weigh all the pros and cons.

• Born with Straight Ears: A Curl kitten’s ears only begin to curl a few days after birth (from 3 to 10 days) and reach their final shape by four months of age.
• The Curl Gene is Dominant: To get kittens with curled ears, only one parent needs to be a Curl. If both parents are Curls, the probability of “curled-ear” kittens is higher.
• Varying Degrees of Curl: The angle of the ear’s curl can range from barely noticeable to a full semi-circle (90-180 degrees). A more pronounced curl is preferred for shows, but any degree makes the cat unique. Cats with straight ears (born from Curls) are also valuable for breeding because they carry other desirable breed traits.
• “Elfin” Appearance: Because of their ear shape and large, expressive eyes, Curls are often compared to elves or forest sprites.
• Two Coat Varieties – One Breed: Unlike many other breeds where longhair and shorthair varieties are registered separately, the American Curl is recognized as a single breed with two coat types. Longhaired and shorthaired Curls can be born in the same litter.
• The First Recognized Breed with an Ear Mutation without Health Defects: Unlike the Scottish Fold, whose gene is linked to bone and joint problems, the American Curl gene has no known negative health consequences.
• Not Just an American Breed: Despite the name, American Curls have gained popularity in many countries worldwide, including Europe and Asia.
• Comparison with Other Breeds: They are sometimes compared to another American breed, the American Wirehair, which also originated from a spontaneous mutation, but one that affected the texture of the coat rather than the shape of the ears.

Do American Curls’ ears hurt because of their shape?

No, the curled shape itself does not cause the cats pain or discomfort. The cartilage is only firm at the base, and the tips remain flexible. However, due to the unique structure, the outer ear may be more prone to earwax buildup, requiring regular cleaning to prevent infections.

Are all American Curl kittens born with curled ears?

No, kittens are born with straight ears. The curling process begins at 3-10 days of age and stabilizes by four months. Additionally, since the Curl gene is dominant but not all breeding cats are homozygous for it, a litter may contain kittens with both curled and straight ears (known as “Curl-straights”).

Do American Curls shed a lot?

Shedding in Curls is moderate. Thanks to their minimal undercoat, they shed less than many other breeds, especially longhaired ones. Major shedding is seasonal, occurring in spring and fall. Regular brushing helps control the amount of hair in the house.

Are American Curls suitable for apartment living?

Yes, American Curls adapt well to apartment life, provided they are given enough space for play, plenty of toys, scratching posts, and most importantly, attention and interaction from their owners. Their need for activity must be met with daily playtime.

Can I leave an American Curl alone for a long time?

This breed does not handle solitude well. They are very attached to people and need companionship. If you are regularly away from home for extended periods, a Curl may get lonely, stressed, and even develop behavioral problems. In such cases, it would be better to get another companion animal or choose a less socially dependent breed.

Are American Curls hypoallergenic?

No, American Curls are not a hypoallergenic breed. Allergies in people are caused by the Fel d 1 protein, which is found in a cat’s saliva, skin oils, and urine, not the fur itself. Although Curls have a minimal undercoat and shed moderately, they still produce this allergen. People with cat allergies should spend time with representatives of the breed before getting a Curl to test their reaction.

The American Curl is a truly unique and charming cat breed that wins hearts not only with its unusual ears but also with its wonderful personality. Playful, gentle, smart, and endlessly devoted to their humans, they become ideal companions for active families and individuals who are ready to give them attention. Their relatively robust health and simple care make them even more appealing. If you’re looking for a cat with a vibrant personality that will remain a playful kitten at heart for life and give you a sea of love and positive emotions, the American Curl might be your perfect choice.
