About the Cornish Rex

The Cornish Rex originated in 1950 in Cornwall, England, when a curly-coated kitten named Kallibunker appeared in an otherwise normal litter on a farm. This small-to-medium breed weighs 5–10 pounds and has a distinctive greyhound-like body — arched back, tucked waist, and long, slender legs built for speed. Their coat is uniquely composed of only the soft, curly down layer — lacking the outer guard hairs and middle awn hairs that other cats possess — creating a washboard-like wave pattern.

Temperament & Personality

Cornish Rex cats are energetic, acrobatic, and endlessly entertaining — they retain their kitten-like playfulness well into their senior years. They are extremely social, love to be held and handled, and will seek out the warmest lap or blanket in the house. They thrive with children and other active pets, and their clownish antics make them natural performers.

Pros

  • Minimal shedding — soft, wavy coat produces less loose hair than most breeds
  • Extremely active and entertaining — loves to play fetch and perform acrobatic leaps
  • Warmth-seeking and cuddly — an ideal lap cat and bed warmer
  • Highly social and does well in busy, active households

Cons

  • Thin coat provides little insulation — sensitive to cold and drafts
  • Prone to hair loss (hypotrichosis) and skin oil buildup requiring regular bathing
  • High metabolism means they eat more relative to their size and can be picky eaters
  • Can be demanding of attention and may act out if bored or ignored

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
