The Oriental Shorthair is generally a healthy, long-lived breed. According to The International Cat Association (TICA), Orientals "can live longer than other cat breeds, reaching an above average life expectancy and have been known to live 20+ years." Most well-bred Orientals live 15-20+ years with reasonable veterinary care. But the breed does have two specific medical considerations every owner should know about: amyloidosis and anesthesia sensitivity.
Per TICA's official breed page, Oriental Shorthairs have a 10+ year minimum life expectancy and routinely reach 20+ years. The breed's longevity is partly attributed to its lean body type and a relatively narrow genetic founder population that has been carefully expanded through outcrossing rather than line-breeding.
TICA officially identifies amyloidosis as a condition Oriental Shorthairs "can be susceptible to." Amyloidosis is a metabolic disease in which abnormal protein fibers (called amyloid) deposit in organs — most commonly the liver and kidneys in cats — eventually compromising organ function.
TICA states directly that "to date there is no test available to detect Amyloids." Research is ongoing — multiple veterinary schools have active research programs — but as of TICA's published guidance, no consumer DNA test can predict which cats will or won't develop the condition.
Until a reliable test exists, the responsible breeder approach is: track parent and grandparent health histories carefully, retire any breeding cat that shows clinical signs of amyloidosis, and partner with owners on early-warning vet checks. Buyers should schedule comprehensive annual senior vet exams from age 8 onward.
Clinical signs to watch for: increased thirst and urination, weight loss despite normal appetite, lethargy, vomiting, jaundice. If you notice any of these, schedule an immediate vet visit including bloodwork and urinalysis.
TICA explicitly flags anesthesia sensitivity as a breed-specific concern: "They have a tendency to be sensitive to anesthesia. It is important to make the veterinarian aware of this before any type of surgery. This includes routine surgeries such as neutering, spaying and dental cleanings."
In practical terms: every Oriental Shorthair veterinary visit involving sedation needs explicit pre-notification. Tell the vet "this is an Oriental Shorthair, Siamese breed group — please use breed-appropriate anesthesia protocols and lower doses." Most experienced veterinarians know to use isoflurane or sevoflurane rather than older injectable agents.
HCM is the most common heart disease in cats overall — not specific to Oriental Shorthairs, but documented in the breed. For Orientals, HCM screening is done primarily through annual or biennial cardiac ultrasound (echocardiogram) by a veterinary cardiologist for breeding cats.
At Royal Oriental Cattery, every cat used for breeding is screened by veterinary cardiac evaluation prior to producing a litter, and we offer a 2-year HCM guarantee on every kitten — if HCM presents within 24 months of go-home date, we work with the family on replacement or refund.
PRA is a group of inherited eye diseases that cause gradual degeneration of the retina, eventually leading to blindness. Commercial DNA tests for feline PRA mutations are available, including markers relevant to breeds in the Oriental/Siamese genetic group that share ancestry with Abyssinian and Russian Blue outcrosses from the 1950s.
Royal Oriental breeding parents are DNA-tested for PRA-related markers before any planned litter — this is standard for every breeding pair in our program. PRA DNA testing on individual kittens is available on request as an add-on service (additional fee passed through to client at lab cost). Most pet families don't request it because both parents are already tested; serious breeder-buyers sometimes do.
Known genetic disease markers: PRA, PKD, and a broad panel of recessive disease markers shared across feline breeds.
Color and pattern verification: coat color genetics, pattern genes (agouti, dilute, etc.).
Coat type verification: shorthair vs longhair.
Parentage verification: confirms the documented sire and dam are biologically the parents — critical for TICA registration accuracy.
What we cannot DNA-test: amyloidosis (no commercial test available per TICA), and HCM specifically in Oriental Shorthairs (no breed-validated genetic test — we use echocardiogram instead).
If your kitten develops a diagnosed congenital or genetic disease within 12 months of the go-home date, we will work with you on replacement of equivalent value OR refund (your choice). Documented vet diagnosis required.
If a board-certified veterinary cardiologist diagnoses HCM in your Royal Oriental kitten within 24 months of go-home, we provide replacement or refund per contract terms.
For the entire lifespan of your Royal Oriental kitten — whether 1 year or 20 — we're available by phone, email, and text for breed-specific questions. Your kitten remains part of our extended cattery family.
Three kittens from our December 2025 litter are ready now. $4,500 flat, includes TICA registration, DNA panel results on both parents, 1+2yr guarantees, lifetime breeder support.
