Scottish Fold genetics
The folded ear of the Scottish Fold is produced by a dominant mutation in the TRPV4 gene (Fd). Because the same mutation affects cartilage development throughout the body, every Fold carries a degree of risk for a condition called osteochondrodysplasia (SFOCD).
Two important facts shape what responsible breeding looks like:
- The condition is dose-dependent. Homozygous cats (Fd/Fd) develop severe, painful skeletal deformity. Heterozygous cats (Fd/fd) have markedly lower expression.
- Heterozygous cats are produced only by pairing a folded-ear cat with a straight-eared cat — what we call Fold × Straight pairing.
Our breeding protocol
- We never breed two folded-ear cats together. Every Aurelian litter is a Fold × Straight pairing.
- Both parents are DNA-tested for PKD and screened for HCM by echocardiogram annually.
- Breeding cats receive annual orthopedic radiographs of the tail base, tarsal joints, and metatarsal region.
- Any kitten showing radiographic or behavioral evidence of skeletal abnormality is placed as a non-breeding companion with full disclosure and veterinary follow-up paid by the cattery.
Veterinary partnerships
Our practice is co-managed with Dr. Helena Whitfield, DVM, DACVS-SA (orthopedic surgery), and Dr. Marcus Lee, DVM, DACVIM (feline medicine). Both consult on every litter and provide independent oversight of our screening program.
Vaccination & nutrition
Kittens receive their first FVRCP vaccination at six weeks and a booster at nine weeks. Rabies is administered at sixteen weeks per AAFP guidelines. Kittens are fed a mother-and-babycat formula from weaning, with a transition to a joint-supportive adult formula at six months.
Ethical commitments
- Two litters per queen per year, maximum. Retirement at age five into a vetted family home.
- No sale to brokers, pet stores, or homes intending to declaw.
- Kittens placed no earlier than 12 weeks of age.
- Lifetime contractual right of return — we will always rehome rather than allow surrender to a shelter.
