Scottish Fold

The CFA describes the Scottish Fold as a calm, soft-voiced, people-oriented cat. It follows you around the house and enjoys attention without demanding it, and it doesn't do well when left alone for long periods. It's curious, too: when something catches its interest, it's known for sitting bolt upright on its hind legs to take a look. It can be reserved with strangers and other cats at first.

There's an important caveat here. Cats Protection points out that some of the Scottish Fold's much-praised "calm, laid-back" temperament may actually come from pain: a cat with sore joints jumps less, plays less and seems more sedentary. Cats are very good at hiding pain. So a Scottish Fold that seems "very calm" may be showing a health sign, not just a personality trait.

Ears are an important part of how cats communicate with each other. Cats Protection notes that folded ears can make it harder for a cat to signal its feelings to other cats, and the CFA mentions that other cats may read the folded ears as a sign of hostility.

This section is different from our other breed pages. UFAW, International Cat Care and Cats Protection say clearly that folded-ear cats should not be bred. In 2024, 12 organizations, including the GCCF, the RSPCA and the British Small Animal Veterinary Association (BSAVA), issued a joint statement objecting to the breed being featured in a film. That's why we don't recommend this breed if you're looking for a new cat.

Cats Protection also points out that Scottish Folds can be more expensive to care for and to insure because of their health problems.

According to the CFA, in 1961 a shepherd named William Ross spotted a white, copper-eyed female cat with forward-folded ears on a farm in the Tayside region of Scotland. Snooks, one of the kittens of this cat, Susie, was bred first to a domestic cat and then to a British Shorthair, laying the foundation of the breed. The folded ear is caused by a dominant gene change that arose spontaneously.

In Britain, the GCCF recognized the breed only briefly. According to UFAW, the GCCF had removed it from its list of recognized breeds by 1974 because of the severe deformities seen in the legs and tail. FIFe doesn't recognize the breed either: under its 2026 rules, cats with osteochondrodysplasia, or with such a cat in their ancestry, can't be registered, bred or shown with FIFe, and the Scottish Fold's breed abbreviations were deleted from its list in 2012.

Breeders in the United States kept the breed going. The CFA granted championship status to the shorthaired Scottish Fold in 1978 and to the longhair in 1992, and accepted straight-eared cats in 2022.

"Round" is the word most often used to describe this breed. The head is round, the eyes are big and round, the neck is short, and the body is medium-sized and well padded. The ears are small and fold forward like a cap.

• Ears: Kittens are born with straight ears. According to UFAW and the CFA, the ears start to fold at 3 to 4 weeks of age, so you can't tell in the first weeks whether a kitten's ears will fold.
• Straight-eared cats: When a folded-ear cat is bred to a straight-eared cat, about half of the kittens have folded ears. The straight-eared cats are called Scottish Straights or Scottish Shorthairs.
• Coat: Dense and plush in shorthairs; semi-long to long in longhairs.
• Colors: According to the CFA, any genetically possible color and pattern is accepted.
• Tail: The CFA standard calls for a flexible, tapering tail and disqualifies a tail that is thick, shortened or lacks flexibility. A stiff tail is one of the early signs of the joint disease described below.

Caring for a Scottish Fold should focus on protecting its joints and spotting pain early.

• Coat: According to the CFA, combing once a week is enough for shorthairs; longhairs need more frequent combing to prevent mats. Cats Protection notes that cats with joint pain struggle to groom, especially their back, tail and hind legs, so tell your vet if the coat starts to look unkempt.
• Ears: Cats Protection recommends checking the ears regularly for debris, odor and irritation. If cleaning is needed, use a product your vet recommends.
• Home setup: Ramps, low steps and cat trees help a cat that struggles to jump still reach its favorite spots. For ideas, see our article on why cats love high places.
• Easy access: Cats Protection recommends putting steps up to favorite resting spots and using a litter box with low sides for cats with joint pain. Starting to avoid a high-sided litter box can itself be a sign of pain.
• Tail check: Gently hold the tail and check its flexibility; if you notice stiffness or discomfort when it's touched, tell your vet.
• Play: Choose short games close to the ground that don't involve jumping.

A Scottish Fold doesn't need a special food; a complete, balanced cat food suited to its age is enough. Weight matters especially for this breed, though: every extra ounce means more load on joints that are already affected. The 2024 study by Teng and colleagues showed that cats whose weight was further from the median for their breed and sex lived shorter lives.

• Measure food, and set an ideal weight with your vet.
• Cats Protection recommends asking your vet about special diets or supplements that may help the joints; don't start supplements on your own.
• Weigh your cat once a month; a cat that moves less gains weight easily.
• Always have fresh water available.

Scottish Fold osteochondrodysplasia

Osteochondrodysplasia is an inherited disorder that affects the development of cartilage, and with it bone, throughout the body. According to UFAW, it's also why the ear folds: the ear cartilage can't support the ear's weight. The same disorder has far more serious effects in the leg bones, joints and tail. A genome study in 2016 linked the folded ear and osteochondrodysplasia to a single change in a gene called TRPV4, which plays a role in how cartilage cells respond to pressure and movement.

• Which cats are affected? According to UFAW, in cats carrying two copies of the gene, the disease starts early and is severe; in cats with one copy it progresses more slowly and ranges from mild to severe. There are no unaffected carriers: every folded-ear cat is affected to some degree.
• When does it start? According to Cats Protection, changes can be seen on X-rays of kittens as young as 7 weeks, and signs such as limping can begin at 4 to 6 months. The condition worsens with age and doesn't go away.
• What does it cause? Short, thick legs, a thick and inflexible tail, swollen ankles and wrists, bony growths and painful joint inflammation (arthritis).

There is some debate around the details. A 2023 study of Australian veterinary records found a confirmed osteochondrodysplasia diagnosis in only 1.1 percent of 1,131 Scottish Folds and a suspected one in about 5.7 percent, though the authors note that the records may be incomplete. In a small 2023 study in Italy, only one of 12 Scottish Folds carrying the gene showed clinical signs. So severity varies a great deal from cat to cat. But because cats hide pain well, not seeing signs doesn't mean there's no pain, which is why welfare organizations agree the breed should not be bred.

There's no cure. Your vet can discuss options for reducing pain; Cats Protection mentions that a vet-supervised trial of pain relief can show whether a cat becomes more active.

How can you tell if your cat is in pain?

According to Cats Protection, cats are very good at hiding joint pain and are less likely than dogs to limp obviously; changes start subtly. Watch for:

• Jumping less, avoiding high places or struggling to get up
• Stiffness after rest that eases with movement
• Grooming less, with an unkempt coat on the back and tail
• Avoiding the litter box or going next to it
• Hiding more, playing less or getting irritable when touched
• A stiff tail or swollen ankles

Other health issues

• Polycystic kidney disease (PKD): According to Cats Protection, Scottish Folds are at greater risk of this inherited kidney disease, and there's a test for the gene that causes it. In a Japanese study published in 2025, 70 of 300 cats carrying the PKD gene were Scottish Folds.
• Flat-face problems: According to Cats Protection, some Scottish Folds have short noses, which can lead to breathing, dental and eye problems.

There's no reliable lifespan data for the Scottish Fold. In a 2024 VetCompass study of more than 7,900 cats that died in the UK in 2019, the Scottish Fold wasn't among the 12 groups with at least 15 recorded deaths that could be analyzed separately (the GCCF doesn't register the breed in the UK).

For this breed, the real question isn't "how long does it live?" but "how does it live?" Osteochondrodysplasia doesn't kill a cat directly, but lifelong pain and limited movement can deeply affect quality of life. UFAW notes that some severely affected cats are euthanized at a young age for welfare reasons. Regular checkups, pain management, a healthy weight and a cat-friendly home setup are the most concrete things you can do to help your Scottish Fold live more comfortably.

• Think twice about buying a kitten: UFAW, International Cat Care and Cats Protection want the breeding of folded-ear cats to stop. According to studies cited by UFAW, if no folded-ear cats were bred from, the disease would disappear within a generation.
• If it's the temperament you want: UFAW cites researchers who suggest that people who want the same gentle temperament consider straight-eared cats that don't carry the gene. Shelter cats come in every temperament, too.
• Banned in some countries: Breeding folded-ear cats was already illegal in the Netherlands, and since January 1, 2026 keeping them is banned as well. Cats born before that date and microchipped may live out their lives but can't be shown; violations can bring an administrative fine of €1,500. According to Cats Protection, breeding Scottish Folds in Scotland likely breaches the conditions of breeding licenses.
• Registries: The GCCF and FIFe don't register the breed; the CFA does, and advises breeding folded-ear cats only to straight-eared cats, along with DNA testing. Rules vary by country.
• If you already have a Scottish Fold: Get your cat spayed or neutered (Cats Protection notes this stops the gene being passed on), schedule regular checkups and learn the signs of pain.
• Registration: Rules vary by country; many places require or recommend microchipping. In Türkiye, owned cats must be microchipped and registered in the PETVET system.
