About the Korat

The Korat is one of the oldest natural cat breeds — originating in Nakhon Ratchasima (historically called "Korat") province of Thailand and documented in the Tamra Maew as early as the 14th century. This small-to-medium breed weighs 6–10 pounds and has a semi-cobby, muscular body with a distinctive heart-shaped face and large, luminous green eyes. Their single coat is exclusively silver-tipped blue — each hair is lighter at the root and tipped with silver, giving the entire cat a shimmering, halo-like appearance.

Temperament & Personality

Korats are gentle, intelligent cats that form extraordinarily strong bonds with their families and prefer quiet, stable environments. They can be shy with strangers but are deeply devoted to their people — often choosing one person as their absolute favorite. They do well with respectful children and calm companion cats, though they tend to assert dominance over other pets in the household.

Pros

  • Stunning silver-blue coat with a unique shimmering "halo" effect
  • Naturally healthy with a long lifespan — often living 15–20 years
  • Extremely loyal and forms deep, lasting bonds with their owner
  • Single coat sheds very little and requires minimal grooming

Cons

  • Prone to GM1 and GM2 gangliosidosis — fatal genetic storage diseases (testable)
  • Startles easily and is sensitive to loud noises and sudden movements
  • Can be possessive of their owner and jealous of other pets
  • Very low body fat — sensitive to anesthesia and temperature changes

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
