1General appearance and body structure
The Sphynx is a medium-sized, strong and well-muscled cat. Despite its seemingly delicate appearance, it should be surprisingly heavy for its size. Its body is medium in length, well proportioned and solidly built, without appearing cumbersome.
A broad, rounded chest and a full, distinctly rounded abdomen are characteristic features. This does not mean that the cat should be overweight. A Sphynx should be firm, muscular and physically fit.
The neck is of medium length, well muscled and slightly arched, particularly strong in adult males. The legs are in proportion to the body, with the hind legs slightly longer than the front legs. The wide-set forelegs emphasise the characteristic shape of the chest.
The paws are oval, with long, slender, prominent toes. Thick paw pads give the impression that the cat is walking on small air cushions.
The tail should be slender, in proportion to the body, broader at the base and gradually tapering towards the tip. A small tuft of fur at the tip is permitted and is known as a lion tail.
2Head, profile, ears and eyes
Head and muzzle shape
The Sphynx head is a modified wedge with rounded contours. It should be slightly longer than it is wide, with a gently rounded skull and a flat forehead.
Prominent cheekbones are particularly important, giving the head its characteristic expression. The muzzle should be strong and rounded, with a firm, well-defined chin.
Profile and stop
Viewed from the side, the Sphynx should have a straight nose bridge and a slight to moderate stop, the change in the profile line where the forehead meets the nose.
Ears
Large ears are one of the Sphynx’s most recognisable features. They should be broad at the base and open, with gently rounded tips. They should be set at a slight angle to the head, without flaring excessively outwards.
The inside of the ears should be hairless. A small amount of hair is permitted on the lower outer edges and on the backs of the ears.
Eyes
Sphynx eyes are large, characteristically lemon-shaped and slant towards the outer edges of the ears. The distance between them should be slightly greater than the width of one eye.
The standard permits various eye colours, which should harmonise with the skin colour.
3Sphynx skin: suede, not rubber
This is one of the most important and most frequently misunderstood elements of the breed standard.
The Sphynx should give the impression of being hairless, but its skin should have a characteristic suede-like texture. It may be covered in very short, fine down that is almost invisible to the naked eye. When stroking some cats, a slight resistance can be felt, rather like running a hand over soft suede.
Is a more hairless Sphynx a better Sphynx?
No. Some breeders use the term ‘rubber’ for cats with exceptionally smooth, almost entirely hairless skin. Some regard this degree of hairlessness as a particular advantage, but the FIFe standard does not reward the greatest possible absence of hair.
The official standard describes a suede-like skin texture and allows fine down. In her webinar ‘Naga prawda o sfinksach’ (‘The Naked Truth About Sphynx Cats’), international FIFe judge Anna Wilczek also points out that a distinctly rubbery skin texture is undesirable.
This does not mean that every Sphynx must have visible hairs. Conformity to the standard depends not only on the amount of hair, but also on the quality and texture of the skin. A cat does not become a better representative of its breed simply because it is more hairless than others.
Where may a Sphynx have hair?
The FIFe standard permits short, soft, fine hairs on the paws, nose bridge (often described as ‘peach fuzz’), cheekbones, backs of the ears, tail tip and, in males, the scrotum.
Natural hair should not be removed to make a cat look more hairless. FIFe states that any evidence of hair removal precludes the award of a show certificate.
4Wrinkles, whiskers and colour
Wrinkles
Wrinkles are a desirable Sphynx feature, particularly around the muzzle, between the ears and on the shoulders. They are often most visible in kittens, whose skin is relatively loose.
This does not mean that more folds are always better. The standard states that wrinkling must not be so pronounced that it interferes with the cat’s normal functions. Excessive skin folds should not be a breeding goal.
Whiskers
Canadian Sphynx cats usually have rudimentary, very short whiskers, and some have none at all. This is one of the breed’s characteristic features.
Colours and patterns
FIFe permits all colours and patterns provided for in the Sphynx standard, including any amount of white.
In the EMS system, Sphynx cats use only code 21 for tabby, without distinguishing individual tabby patterns. The codes for silver (s) and golden (y), and pattern codes 11, 12, 22, 23, 24 and 25, are not used. These designations are used in pedigrees and feline registration documents; I explain their meaning in more detail in the article ‘Sphynx colours and FIFe EMS codes’.
Because Sphynx cats lack a conventional coat, identifying their colour can be difficult. In my breeding experience, this is particularly true of some shades of red and cream. A kitten may initially look cream, but develop stronger pigmentation as it grows and turn out to be red.
This is a practical observation from breeding, rather than a separate rule in the breed standard.
5How does the Canadian Sphynx differ from the Peterbald and the Don Sphynx?
The Canadian Sphynx, Don Sphynx and Peterbald are three separate breeds. The table below compares their physical features based on the 2026 FIFe standards, with practical breeding observations added to the description of whiskers. These descriptions concern the typical appearance defined by the standards; they do not replace a pedigree or an individual assessment of a cat.
| Feature | Canadian Sphynx | Peterbald | Don Sphynx |
|---|---|---|---|
| Body | Medium in length, strong and muscular; broad, rounded chest and full abdomen | Slender, elegant, elongated oriental-type body, well muscled | Medium in length, muscular, with a broad chest, strong shoulders and broad hips |
| Head | Modified wedge with rounded contours, slightly longer than wide | Long wedge with straight lines, widening towards the ears | Wedge, slightly longer than wide, with prominent brow ridges |
| Eyes | Large, lemon-shaped and slanting | Almond-shaped and slanting | Medium-sized, almond-shaped and slightly slanting |
| Profile | Straight nose bridge; slight to moderate stop | Long, straight nose; slightly convex skull in profile | Medium-length, straight nose, with a defined transition to the forehead |
| Coat | Suede-like skin texture; fine down, including possible hair on the nose bridge (‘peach fuzz’), and short hair in specified areas | Various coat types, from hairless to coated varieties | Wrinkled skin; hairless varieties and various coat types |
| Whiskers | In practice, often very short, rudimentary or absent; FIFe describes them as whole or broken, coarse | Curled, coarse and of varying lengths; may be rudimentary or absent in hairless varieties | Coarse and curled; may be long or broken |
One characteristic feature of the Canadian Sphynx is the fine hair on the nose bridge, often called ‘peach fuzz’. However, it is not present in every individual and cannot, by itself, reliably distinguish the Canadian Sphynx from other hairless breeds. The clearest difference is in body type: the Canadian Sphynx has a strong, muscular body with rounded proportions, while the Peterbald is slender, elongated and oriental in type.
6FIFe and WCF: comparing Canadian Sphynx standards
The following table compares the requirements stated in the FIFe and WCF standards. It highlights differences in their descriptions; it does not establish which organisation judges cats more strictly.
| Feature | FIFe | WCF |
|---|---|---|
| Head | Modified wedge with rounded contours, slightly longer than wide | Rounded modified wedge, only slightly longer than wide |
| Muzzle | Strong and rounded, with a defined chin | Short, strong, clearly defined and rounded |
| Profile | Straight nose bridge; slight to moderate stop | Slight stop at the base of the nose |
| Whiskers | Whole or broken, coarse | Desirable |
| Ears | Large, broad at the base and open; upright, set at a slight angle, without pronounced outward flaring | Exceptionally large, broad at the base and set wide apart |
| Eyes | Large, lemon-shaped, slanting towards the outer edges of the ears | Large, lemon-shaped and slightly slanting |
| Body | Strong, well muscled and medium in length, with a broad chest and a full, rounded abdomen | Medium-sized, muscular and stocky, with relatively fine bone structure |
| Skin | Suede-like texture; folds particularly around the muzzle, between the ears and on the shoulders; fine down and hair in permitted areas | Fine down and skin folds, particularly on the forehead, neck and legs |
| Tail | Slender and in proportion, broader at the base and tapering towards the tip | Long, slender and whip-like |
| Faults listed in the standard | Under ‘Faults precluding the certificate’: any evidence of hair removal. | Under ‘Faults’: a strong resemblance to the Devon Rex or Cornish Rex is a serious fault. |
Table sources: FIFe SPH, DSP and PEB standards (2026) and the WCF Canadian Sphynx standard dated 1 January 2010. Descriptions of appearances encountered in breeding supplement the standards’ requirements.
FIFe identifies a feature that precludes a certificate, whereas WCF lists a serious fault. These are different assessment categories and should not be treated as equivalent.
The comparison is based on the FIFe SPH standard (2026) and WCF Canadian Sphynx standard (version published by WCF).
FIFe specifies head proportions and ear placement, while WCF emphasises exceptionally large ears and a short, strong muzzle. Both documents set detailed requirements for anatomy, skin and proportions, although they describe them differently.
The organisation of shows is a separate issue: FIFe has four breed categories, while WCF has five, including a hairless category. Depending on entries and the applicable rules, this changes the group of competitors in Best in Show selection. A separate article explains the details: ‘How to read cat show results’.
7How is the modern Sphynx type changing?
Although the basic principles of the standard have remained similar for many years, I have observed that some breeders prefer a slightly shorter, more rounded muzzle and a more pronounced stop. These features give the Sphynx head a stronger, more distinctive expression.
This does not mean that the official standard has changed. FIFe still requires a modified-wedge head, slightly longer than wide, with a slight to moderate stop.
Crucially, shortening the muzzle must not lead to exaggerated anatomical changes. A correct bite, healthy eyes and the ability to breathe and eat freely remain paramount.
A good breeding type should combine the Sphynx’s distinctive appearance with health and sound anatomy.
8The breed standard and show assessment
At a show, the judge compares the cat with the official breed standard. Each group of features is allocated a number of points, allowing the judge to assess how closely the cat’s appearance matches the standard.
| FIFe feature group | Points | WCF feature group | Points |
|---|---|---|---|
| Head, including eye shape | 25 | Head | 30 |
| Ears | 10 | Eyes | 5 |
| Body, neck, legs, paws and tail | 35 | Body | 35 |
| Quality and texture of skin and coat, wrinkles | 25 | Hairlessness and wrinkles | 25 |
| Condition | 5 | Condition | 5 |
| Total | 100 | Total | 100 |
The federations group features differently. In FIFe, the head comprises five elements worth 5 points each: shape, profile, muzzle and chin, cheekbones, and eye shape. Ears have a separate allocation. WCF lists eyes separately but does not give ears their own category.
The overall structure and appearance are assessed. A Sphynx with exceptionally large ears but incorrect body proportions will not automatically be better than a cat with a more balanced body.
I describe the detailed rules for judging, awarding certificates and titles, and the differences between FIFe and WCF shows in a separate article: ‘How to read cat show results’.

10Frequently asked questions (FAQ)
Does a Sphynx have to be completely hairless?
No. The standard allows very fine down. The most important requirement is the characteristic suede-like skin texture.
Is a Sphynx with rubbery skin better?
No. Complete hairlessness does not earn extra credit. In her training materials, Anna Wilczek identifies a rubbery skin texture as undesirable.
Can a Sphynx have whiskers?
Yes. They may have short or broken whiskers, although in my breeding experience I also often encounter Sphynx cats with none at all.
Should a Sphynx have a great many wrinkles?
Wrinkles are desirable, particularly around the head and shoulders, but excessive wrinkling must not interfere with the cat’s normal functions.
Does a shorter muzzle mean better conformity to the standard?
Not automatically. Correct head proportions, prominent cheekbones, a strong chin and a slight to moderate stop are the most important features.
Is a cat with a show title always suitable for breeding?
No. Show assessment primarily concerns conformity to the breed standard. Health, preventive screening, genetics, pedigree and temperament are equally important in breeding.
Summary
The Sphynx standard describes a medium-sized, muscular cat with balanced proportions, a distinctive head, large ears and suede-like skin. Although the absence of a conventional coat is the breed’s most recognisable feature, it should not overshadow the importance of its other characteristics.
Responsible breeding aims to preserve the characteristic Sphynx type without compromising health, physical function or welfare.
