Visual Differences
Telling a Oriental Shorthair from a Peterbald
Orientals wear a fine short coat in hundreds of colors. Peterbalds are hairless or near-hairless, developed in Russia by crossing Donskoy and Oriental Shorthair lines, and come in five coat types rather than one.
Oriental Shorthair Key Markers
- Long, tapering wedge-shaped head forming a triangle from the nose tip to the ear tips — the CFA standard calls for a wedge starting at the nose and flaring out in straight lines to the ear tips; the skull is flat, the nose is long and straight with no stop, and the chin is medium in size with the tip of the chin in vertical line with the nose tip
- Large, wide-set, almond-shaped eyes slanted toward the nose — set at an angle that follows the wedge lines; eye color is solid green in most colors (blue in whites, odd-eyed in bi-colors); the vivid green against a warm chestnut or ebony coat is one of the breed’s most striking features
- Very large, pointed ears wide at the base — set continuing the wedge lines so the face forms an equilateral triangle from nose tip to ear tips; the ears are one of the defining features of the breed, giving the head its extreme angular silhouette
Peterbald Key Markers
- Five coat types per the TICA standard — bald (completely hairless), chamois (fine suede-like down), flock (velour-like fuzz with no guard hairs), brush (short wiry or wavy hair), and straight (a regular coat); one litter can produce several types
- Long wedge head with a straight profile, the classic Oriental shape — a long muzzle and a strong chin
- Very large, wide-set, almond-shaped ears, set to continue the wedge lines
Temperament & Personality
Oriental Shorthair
- Extremely vocal and communicative — carries on conversations with owners in a loud, demanding voice identical to the Siamese; will "tell you about their day" and voice displeasure at closed doors or empty food bowls
- Intensely people-oriented — follows owners from room to room, sleeps on or next to their person, greets at the door, and hates being left alone; the breed is not suited to owners who are away from home for long hours
- Highly intelligent and curious — opens cabinets, turns on faucets, learns tricks, and solves puzzle feeders; needs significant mental stimulation or boredom leads to destructive behavior
- Extremely active and athletic — jumps to the highest perches, plays fetch, and stays kittenish well into senior years; needs cat trees, interactive toys, and daily play sessions
- Social with visitors and other pets — the wedge-head breeds are famously outgoing; Orientals greet strangers, get along with cat-friendly dogs, and enjoy multi-cat households
- Sensitive to cold — the short, fine single coat offers minimal insulation; Orientals seek warm spots, heated beds, sweaters, and under-the-covers sleeping
Peterbald
- Affectionate and people-oriented — follows owners, greets at the door, and wants to be part of everything
- Intelligent and curious — learns tricks, opens doors, and solves puzzle feeders
- Active and playful — enjoys interactive toys and climbing; stays kittenish into adulthood
- Dog-like loyalty — forms deep bonds and often walks on a leash
- Social with strangers, children, and other pets — rarely shy or territorial
- Heat-seeking — bare skin offers no insulation; Peterbalds want warm spots, sweaters, and laps
Health Notes
Oriental Shorthair
- Progressive retinal atrophy (PRA) — a retinal degenerative disease linked to the same rdAc mutation found in Siamese lines; affected kittens show night blindness as early as 8-12 weeks, progressing to complete vision loss over 2-4 years; DNA testing available and recommended before breeding
- Feline asthma and bronchial disease — the breed shows a higher incidence of chronic lower airway disease than most cats, likely inherited from Siamese ancestry; symptoms include coughing, wheezing, and labored breathing; triggers include dust, pollen, smoke, and aerosol sprays; diagnosis requires chest X-rays and bronchial washings; treatment involves corticosteroids and bronchodilators
- Amyloidosis — a condition where amyloid protein deposits accumulate in the liver, leading to progressive liver dysfunction; inherited from Siamese ancestry; common early sign is unexplained weight loss despite normal appetite; diagnosed through bloodwork (elevated liver enzymes) and liver biopsy; some cases respond to medication, but the condition is often progressive
- Dental disease — the long narrow muzzle structure contributes to tooth crowding, early gingivitis, and tooth resorption; the breed needs regular dental care and annual professional cleanings starting from young adulthood (as early as 2-3 years old)
- Sensitivity to anesthesia — all svelte-type breeds with low body fat percentage have a narrower anesthesia safety margin; pre-anesthetic bloodwork and a thorough veterinary assessment are essential before any surgical procedure
- Crossed eyes (convergent strabismus) — a harmless genetic trait inherited from Siamese ancestry where the eyes turn inward slightly; does not affect vision or quality of life but owners should be aware it can occur
Peterbald
- Progressive retinal atrophy (PRA) — a genetic eye disease documented in the breed that causes slow vision loss; DNA testing available and recommended before breeding
- Skin care needs — without hair, skin oils build up into greasy film, acne, and yeast issues; regular gentle bathing is necessary
- Sunburn and temperature intolerance — bare skin sunburns easily and offers no warmth; an indoor-only lifestyle with pet-safe sunscreen near windows
- Dental disease — some lines are prone to tooth issues; regular brushing and annual cleanings recommended
- Generally robust — beyond PRA screening and skincare, no breed-specific diseases are documented

Frequently Asked Questions
How can I tell a Oriental Shorthair apart from a Peterbald?
Orientals wear a fine short coat in hundreds of colors. Peterbalds are hairless or near-hairless, developed in Russia by crossing Donskoy and Oriental Shorthair lines, and come in five coat types rather than one.
Are Oriental Shorthairs hypoallergenic?
No — Oriental Shorthairs are not a hypoallergenic breed. Their short coat sheds like any other cat’s, and they produce normal allergen levels.
Are Peterbald cats hypoallergenic?
No — despite the lack of fur, Peterbalds are not hypoallergenic. Allergies are triggered by the Fel d 1 protein in skin oils and saliva, and hairless skin still produces both.
