Scottish Straight

According to the CFA's description of the Scottish Fold breed, these cats are sweet-natured, calm and happiest living close to their people. They are quiet and curious, usually patient with children, and can learn simple tricks. They may be reserved with strangers and with other cats, so it pays not to rush introductions.

The CFA also notes that they don't cope well with being left alone for long stretches. That makes them a great match for someone who is home a lot, or for a family that will set aside time for play and chat every day. If you're away most of the week, consider a second cat or a well-enriched home.

The Scottish Straight suits a calm home, with people who want time with their cat and don't expect a boisterous household.

The Scottish Fold story starts in 1961 in Scotland's Tayside region: according to the CFA, a white farm cat named Susie with folded ears was spotted there. Her daughter Snooks became the foundation queen, and breeders crossed this line with domestic cats and British Shorthairs. The folded ear comes from a dominant gene that appeared by spontaneous mutation.

The Scottish Straight is a natural result of those matings: some kittens born to a folded-ear cat and a straight-eared cat arrive with ears that never fold. For many years those kittens were treated as "off-type" and culled, or used only inside breeding programs. Today different organizations handle them differently:

• CFA: Moved straight-eared Scottish cats to championship status in 2022; the breed now has four divisions, shorthair and longhair, each with folded and straight ears.
• WCF: Lists the longhaired straight-eared variety (Highland Straight) as a recognized breed.
• FIFe: Does not recognize the Scottish Fold; cats with osteochondrodysplasia, or with such a cat in their ancestry, can't be registered, used for breeding or exhibited under FIFe.

For the longhaired line, see our Scottish Longhair (Highland) page.

A medium-sized, round-faced cat with full cheeks. According to the CFA, the Scottish Straight's ears are medium to small with rounded tips, set well apart; that looks a little different from the smaller, higher-set ears of the British Shorthair, though the two breeds are easily confused at first glance. Females can be somewhat smaller than males; the CFA gives no weight range.

• Coat: Dense and plush in the shorthaired variety.
• Colors: The CFA accepts every genetically possible color and pattern: solids, tabbies, tortoiseshells, bi-colors, smokes, shadeds, pointed patterns and more.
• Eye color: Tied to coat color; some white and bi-color patterns can have blue or odd eyes.

The CFA says both the short and long coat varieties get by with weekly combing, shed a little year-round and more in spring and fall. For a shorthaired Scottish Straight, an easy routine is enough.

• Combing: A comb or rubber brush once a week; more often during the shedding season. Check the skin, ears and nails while you comb.
• Nails: A scratching post is a must; trim nails the way your vet shows you.
• Ears: Check them regularly. International Cat Care says redness, itching, head shaking, discharge or odor means the ear should be seen by a vet; ask your vet for advice on cleaning, too.
• Play: Short daily hunting games (wand toys, balls) help with weight and fun; safe high places to climb are welcome.

We found no source suggesting the Scottish Straight needs a special food: a balanced, complete cat food suited to its age and lifestyle is enough. Calm, indoor cats gain weight easily; measure the food rather than eyeballing it, subtract treats from the daily amount, work out the daily amount with your vet and weigh your cat once a month. Needs can change after neutering.

Weight may matter for joints too; talk to your vet about your cat's ideal weight and how to keep it.

The fold gene and the Scottish Straight: the sources don't say exactly the same thing

A Scottish Fold's ears fold because of a dominant change in a gene called TRPV4, and the same change disrupts cartilage and bone development, causing a painful joint disease called osteochondrodysplasia. For details on the disease, see our Scottish Fold page. Whether the Scottish Straight carries it is a two-sided question:

• The expected situation: According to UFAW, straight-eared kittens from a mating between a fold-eared and a straight-eared cat don't carry the gene and don't show the disease; UFAW therefore suggests a straight-eared Scottish to anyone who wants a similar temperament. In a 2023 study in Italy, 17 cats were tested: none of the 5 Scottish Straights carried the gene, while all 12 Scottish Folds were single-copy carriers.
• But looks can fool you: In a 2026 study in Japan, seven cats born with folded ears had their ears straighten as they grew, and all seven carried the gene. The researchers call them "cryptic folds"; they made up about 12.7% of carrier cats. The conclusion: judging by ears alone isn't enough for breeding decisions, DNA testing is needed.
• A more cautious view: Cats Protection writes that even straight-eared cats bred from Scottish Folds may be at risk of progressive joint disease, and recommends veterinary checkups. The gap between the sources shows why testing for the gene itself matters.

So when you're getting a Scottish Straight kitten, ask the breeder for the parents' TRPV4 DNA test results and, if possible, the kitten's own result. A 2025 review in the journal Animal Welfare concludes that breeding cats with curled or folded ears should be avoided. A straight-eared Scottish may be a way to get a similar cat without supporting that breeding, but the chain still starts with fold-eared parents. Weigh that for yourself.

How can you spot joint pain?

Cats hide pain very well. If yours jumps less or climbs less than before, moves stiffly, has started going outside the litter box, hides more or gets grumpy when touched, show your vet. These signs aren't necessarily about the fold gene; age-related joint problems can happen in any cat.

• Polycystic kidney disease (PKD): In a large 2026 study in Japan, the gene change behind PKD was also found in Scottish Folds, and Cats Protection writes that Scottish Folds are at higher risk of this inherited kidney disease. We found no separate source on whether straight-eared Scottish cats carry the same risk; asking the breeder for the PKD test result makes sense.
• Heart: We found no evidence of a breed-specific heart disease for the Scottish Straight. Since heart disease can occur in cats of any breed, regular vet checkups are a good start.

We found no breed-specific lifespan study for the Scottish Straight, so we're not giving a number. In general, ideal weight, regular vet checkups, neutering and a safe home affect lifespan the most; to cut down on inherited risks within the breed, it makes sense to choose a kitten from DNA-tested parents.

• Consider a shelter too: Purebred cats and look-alike mixes end up in shelters and rescues. If you want a straight-eared, short-coated, round-faced cat, look there as well.
• If you buy from a breeder: Ask to see the parents. Ask for the TRPV4 (fold gene) DNA results, the PKD test and vaccination records. Stay away from breeders who mate two fold-eared cats or advertise that "fold kittens may turn up"; even the CFA recommends pairing fold-eared cats only with straight-eared ones.
• Red flags: Sellers who won't show the mother, always have kittens, offer no paperwork, rush you to buy now, or "guarantee" a straight-eared kitten will be problem-free.
• Legal registration: In Türkiye, microchipping and PETVET registration are mandatory for cats. Details in our PETVET registration and microchip post.
• First days: Prepare one quiet room for the new cat; International Cat Care advises starting a new cat in a single room, leaving a hiding place it can retreat to, and letting it come to you rather than forcing contact. Our first week with a new cat post walks you through it.
