About the Devon Rex

The Devon Rex appeared in 1959 in Buckfastleigh, Devon, England — just a decade after the Cornish Rex, though the two breeds' curly coats are caused by entirely different genetic mutations. This small-to-medium breed weighs 5–10 pounds and has an unmistakable pixie-like face with enormous, low-set ears, large oval eyes, and prominent cheekbones. Their short, soft, wavy coat can come in virtually any color or pattern and has a suede-like texture.

Temperament & Personality

Devon Rex cats are mischievous, high-energy clowns that love to perch on shoulders, steal food, and insert themselves into every activity. They are fiercely people-oriented and will follow their owners everywhere — including into the shower if given the chance. They get along splendidly with children, dogs, and other cats, and their playful, affectionate nature makes them impossible to ignore.

Pros

  • Low-shedding, wavy coat — often better tolerated by allergy sufferers
  • Clownish, entertaining personality provides constant amusement
  • Shoulder-riding and lap-sitting habits make them exceptionally affectionate
  • Compact size and adaptable nature suit apartment living perfectly

Cons

  • Prone to hereditary myopathy (a muscle weakness condition unique to the breed)
  • Thin coat means they are always seeking heat — can burn on radiators or heating pads
  • Food-motivated to a fault — will steal food from plates, counters, and even your hand
  • Fragile, curly whiskers often break off, which is harmless but can look unusual

About the Russian Blue

The Russian Blue is a naturally occurring breed believed to have originated in the port city of Arkhangelsk (Archangel) in northern Russia, arriving in Europe aboard trade ships in the 1860s. This medium-sized cat weighs 7–12 pounds and is renowned for its dense, plush double coat of uniform blue-gray with silver-tipped guard hairs that give it a luminous shimmer. Its vivid emerald-green eyes, wedge-shaped head, and enigmatic "Mona Lisa smile" complete an unmistakably elegant look.

Temperament & Personality

Russian Blues are gentle, reserved cats that are intensely loyal to their families yet cautious around strangers. They are creatures of habit who thrive on routine — eating at the same time, playing in the same spots, and sleeping in their preferred perch. Once bonded, they are affectionate and playful, often fetching toys and entertaining themselves with quiet grace.

Pros

  • Produces lower levels of the Fel d 1 allergen — better tolerated by some allergy sufferers
  • Dense double coat is low-shedding and virtually maintenance-free
  • Quiet and well-mannered — rarely destructive or excessively vocal
  • Long-lived breed with few genetic health issues — many reach 15–20 years

Cons

  • Shy and reserved with strangers — may hide during gatherings or parties
  • Sensitive to change — can become stressed by moves, new pets, or schedule disruptions
  • Prone to overeating and weight gain if food is left out freely
  • Can be slow to warm up to new family members or housemates
