Visual Differences

Telling a American Wirehair from a Devon Rex

Devon Rex have short, soft waves and a pixie face with oversized ears set low on the head. American Wirehairs have a harsh, springy coat, a round face, and medium ears set wide apart. The Devon Rex coat is downy; the Wirehair pelt is unmistakably coarse.

American Wirehair Key Markers

  • Wire coat — every hair is bent, hooked, or crimped at the tip, including the whiskers, which curl and hook; the coat is coarse and springy to the touch, denser and harsher than a normal shorthair coat, with the wiry texture most obvious on the back, sides, and tail
  • Round head with a slight whisker break, full cheeks, and a gentle concave curve in profile; the nose shows a gentle concave curve per the CFA standard, with no deep nose break
  • Medium to large, well-muscled body with medium-length legs and firm, full, rounded paws with heavy pads

Devon Rex Key Markers

  • Large, bat-like ears set wide and low on the head — broad at the base with rounded tips and minimal inner fuzz; the most distinguishing feature of the breed, giving the face its characteristic pixie expression
  • Short, soft, wavy coat with a distinct marcel wave pattern — the waves are most prominent on the back and sides; the coat is fine and delicate, with some Devon Rex cats having bald patches, especially on the top of the head and neck
  • Short wedge-shaped head with prominent cheekbones, a short muzzle, and a defined whisker break — the CFA standard calls it a pixie face with a gentle curve from forehead to nose; the whiskers are crinkly and short

Temperament & Personality

American Wirehair

  • Even-tempered and adaptable — takes new people, homes, and routines in stride
  • Playful but not hyperactive — enjoys games and toys, then settles in for a nap
  • Affectionate with family, calm around strangers — friendly without being demanding
  • Good with children and other pets — patient and rarely aggressive
  • Quiet — communicates with soft meows and purrs rather than persistent vocalizing
  • Intelligent and observant — learns routines quickly and responds to its name

Devon Rex

  • Extremely people-oriented — wants to be involved in everything you do, follows from room to room, and sits on your shoulder or keyboard given the chance
  • Mischievous and playful — opens cabinets, steals small objects, and invents games; stays kittenish well into senior years
  • Excellent jumper — routinely reaches the highest perches in the house and watches household activity from above
  • Social with strangers, children, and other pets — rarely shy or territorial, greets visitors at the door like a dog
  • Moderate vocalization — chirps and trills rather than yowling, but will voice displeasure at closed doors
  • Heat-seeking — the short, fine coat offers little insulation, so Devon Rex cats gravitate toward warm spots, sweaters, and under the covers

Health Notes

American Wirehair

  • No breed-specific diseases documented — the CFA breed profile states that despite the close line breeding behind the unique coat, no health problems are characteristic to the breed
  • Hypertrophic cardiomyopathy (HCM) — the most common heart disease in domestic cats, worth screening in any breeding program
  • Obesity — the moderate activity level and hearty appetite make portion control important
  • Dental disease — regular brushing and annual cleanings, as with any cat
  • Coat care caution — the wiry coat should be groomed sparingly; heavy brushing or bathing strips the natural curl and spring, so most owners just run damp hands over the coat weekly

Devon Rex

  • Hypertrophic cardiomyopathy (HCM) — genetic heart disease affecting Devon Rex; echocardiogram screening recommended for breeding cats
  • Congenital myasthenic syndrome (CMS) — a neuromuscular disorder causing generalized muscle weakness, head-bobbing, and easy fatigue in kittens; DNA test available through UC Davis VGL
  • Patellar luxation — kneecap dislocation more common in Devon Rex than many breeds, likely due to fine-boned hind legs
  • Skin sensitivity and dermatitis — the delicate single coat offers minimal skin protection; avoid harsh grooming brushes and over-bathing
  • Dental disease — the narrow muzzle shape contributes to tooth crowding and gingivitis risk; regular dental care particularly important
