Tennessee Rex

The cat world has several curly-coated breeds — the Cornish Rex, the Devon Rex, the German Rex, the LaPerm, the Selkirk Rex, the Skookum — each with its own specific mutation producing curly or wavy hair of varying texture. The Tennessee Rex adds one more to this list, but with a quality that distinguishes it from every other Rex breed: the satin sheen. The Tennessee Rex’s coat does not merely curl — it shimmers. The individual hairs, described by breeders and observers as having a metallic, glass-fiber quality, catch light in a way that gives the coat a visual luster unlike anything produced by any other domestic cat mutation. In good light, a Tennessee Rex’s coat appears to glow from within. This combination of curl and satin light-play, found in no other cat alive, makes the Tennessee Rex one of the most visually distinctive coats in the entire domestic cat world — if, that is, you can find one to look at. The breed is extraordinarily rare.

1. History and Origins: Franklin Whittenburg and Satin Ringo

The Tennessee Rex has a specific, documented origin story that begins with a feral cat in Tennessee in 2004.

Franklin Whittenburg

In 2004, Franklin Whittenburg of Tennessee found a feral male cat with an unusual curly coat that showed a distinctive metallic sheen unlike any Rex cat he had encountered. The cat — named Satin Ringo by Whittenburg — had a coat that was wavy and curly in the Rex manner but with an additional quality: the hairs appeared to have a translucent or reflective inner structure that produced the satin shimmer visible in good light.

Whittenburg, a cat breeder, recognized the potential significance of a Rex mutation with this satin quality and began a breeding program to establish the trait as a heritable foundation for a new breed.

The Satin Gene

The mutation responsible for the Tennessee Rex’s coat is believed to involve not only the hair shaft structure (which produces the curl, as in other Rex breeds) but also the medulla — the inner core of the hair shaft — in a way that produces the distinctive light-reflecting quality. Normal cat hair has a medulla that absorbs light; the Tennessee Rex’s mutation appears to affect the medulla in a way that reflects or transmits light, creating the metallic, glass-fiber shimmer.

This is genetically distinct from all other known Rex mutations. Crossing Tennessee Rex cats with Cornish, Devon, or German Rex cats does not produce the satin quality — confirming that this is a unique mutation rather than a variant of an existing one.

TICA Registration

TICA accepted the Tennessee Rex for experimental new breed registration. The breed remains extremely rare, with a very small breeding population concentrated in Tennessee and a handful of other U.S. states.

2. Appearance: The Satin Shimmer

The Tennessee Rex’s appearance is defined by the specific quality of its coat — a quality that photographs struggle to capture and that requires direct observation in good light to fully appreciate.

The Satin Coat

The coat is curly to wavy in the Rex manner — short, soft, without the protective outer guard hairs of a normal cat coat. In texture, the Tennessee Rex coat is similar to other short Rex coats: soft, plush, and slightly springy. In appearance, it is different from all of them.

The satin quality is a sheen — a metallic, reflective luster visible particularly in direct or angled light — that observers consistently describe as unlike any other cat coat. Descriptions vary: “like glass fiber,” “like liquid metal,” “like the sheen on a piece of raw silk,” “like the cat is lit from within.” The effect is most pronounced in darker coat colors — black and dark brown Tennessee Rex individuals show the satin quality most dramatically — and is visible but less extreme in lighter colors.

The whiskers are also typically wavy or curly, as in other Rex breeds.

Body

The body is medium-sized and well-proportioned, with no structural modifications beyond the coat mutation. The Tennessee Rex is intended to be a normally proportioned domestic cat whose distinction is entirely in the coat. Males weigh approximately 9 to 12 pounds; females 7 to 10 pounds. All colors and patterns are accepted.

Head and Eyes

The head is a moderate wedge with a rounded forehead, medium muzzle, and medium-large ears. The eyes are large and oval and can be any color.

3. Personality: Tennessee Warmth

The Tennessee Rex’s personality has not been as extensively documented as that of established breeds, but consistent reports from Whittenburg and the small community of breeders describe a gentle, affectionate cat.

Gentle and Calm

The Tennessee Rex is described as a gentle, even-tempered cat — not the high-energy assertiveness of some Rex breeds, but a calm, comfortable warmth. It handles its household with equanimity and interacts with its people with a soft, consistent affection.

Affectionate

The breed is described as warmly affectionate — seeking physical contact and enjoying the proximity of its people with the active, gentle sociability characteristic of Rex breeds generally.

Social and Adaptable

Tennessee Rex cats are described as broadly social — comfortable with other animals and adaptable to varying household circumstances. The breed’s temperament reflects the naturally diverse genetic background of its feral foundation cat.

4. Care and Maintenance

The Satin Coat

The Tennessee Rex’s coat requires the same minimal maintenance as other Rex coats — weekly gentle handling or bare-hand stroking, with bathing every four to six weeks to manage skin oils. The satin quality is maintained by the natural coat oils; over-bathing can temporarily diminish the shimmer.

The coat sheds less than standard domestic cats and produces fewer airborne allergens, though the Tennessee Rex is not formally hypoallergenic.

Warmth

As with other Rex breeds, the absence of guard hairs reduces the Tennessee Rex’s cold tolerance. Warm indoor environments and supplementary sleeping warmth are recommended.

5. Health and Lifespan

The Tennessee Rex has an estimated lifespan of 12 to 15 years. As an extremely rare breed founded on a single individual, formal health data is very limited.

Small Gene Pool

The Tennessee Rex’s greatest health vulnerability is its tiny breeding population and the risk of inbreeding that accompanies extreme rarity. Responsible breeders use carefully selected domestic cat partners to maintain genetic diversity.

General Rex Health Considerations

The absence of guard hairs increases skin sun sensitivity and cold vulnerability, as with other Rex breeds. HCM screening is recommended.

6. Is a Tennessee Rex Right for You?

Ideal for:

• Those fascinated by coat mutations and specifically by the satin sheen quality
• Rex cat enthusiasts who want a genuinely unique coat variation
• People willing to support a critically rare breed through responsible acquisition
• Those who want a gentle, calm, warmly social companion

Less ideal for:

• Those who need a widely available breed
• Very cold households without supplementary heating
• People who cannot engage directly with a small, specialist breeder community

Conclusion

The Tennessee Rex has a coat that no other cat alive has — not just curly, but satin-curly, light-reflecting, shimmering with a metallic quality that photographers try to capture and rarely quite succeed in rendering accurately. Satin Ringo brought this quality out of a Tennessee feral colony and into the documented cat world in 2004. The breed that has grown from him since is extraordinarily rare and extraordinarily specific: a cat defined by a visual quality that must be seen in person to be properly understood, possessed by a personality of quiet warmth, living in the hands of a very small community of breeders who are keeping something genuinely unusual alive. The Tennessee Rex is, in the most literal sense, a rare light.
