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 Siamese

The Siamese is one of the most iconic and ancient cat breeds, originating in the kingdom of Siam (now Thailand) and first documented in the Tamra Maew ("The Cat-Book Poems") dating to the 14th century. This sleek, muscular cat weighs 6–14 pounds and is immediately recognizable by its striking colorpoint pattern — a pale cream or fawn body with darker coloring on the face, ears, paws, and tail. The four traditional point colors are seal, chocolate, blue, and lilac, all paired with vivid sapphire-blue almond-shaped eyes.

Temperament & Personality

Siamese cats are among the most vocal and opinionated cats in the world — they will narrate their day in a loud, distinctive raspy voice and expect you to listen. They are fiercely loyal, deeply social, and form intense bonds with their owners, often becoming a one-person cat. Intelligent and active, they need constant stimulation and do best with a companion — whether human, feline, or canine.

Pros

  • Strikingly beautiful with mesmerizing blue eyes and elegant lines
  • Exceptionally intelligent — can learn tricks, walk on a leash, and solve puzzle toys
  • Deeply bonded and loyal to their chosen person
  • Short, fine coat requires almost no grooming

Cons

  • Extremely vocal — constant loud meowing is not for everyone
  • Prone to severe separation anxiety and can become destructive when left alone
  • Susceptible to amyloidosis, asthma, progressive retinal atrophy, and crossed eyes
  • Demanding of attention — may become jealous of other pets or family members
