Visual Differences

Telling a Javanese from a Siamese

Siamese have a short, fine coat and are limited to seal, blue, chocolate, and lilac points. A Javanese is longhaired and pointed in red, cream, lynx, or tortie. The long silky coat is visible from across the room.

Javanese Key Markers

  • Semi-long, fine, silky single coat with no undercoat — lies flat against the body instead of fluffing out, with a full ruff in cold weather and long feathering on the tail
  • Color-point pattern in non-traditional colors — red, cream, lynx, and tortie points on a pale body, the same palette as the Colorpoint Shorthair; the body color deepens with age
  • Long wedge head with a straight profile, a fine long nose, and large pointed ears set wide to continue the wedge lines

Siamese Key Markers

  • Color-point pattern: pale body with darker ears, face, paws, and tail
  • Vivid blue, almond-shaped eyes
  • Short, fine coat that lies close to the body

Temperament & Personality

Javanese

  • Highly vocal — inherited the Siamese voice and uses it constantly, in a raspy, insistent meow
  • People-oriented to a fault — follows owners from room to room and is miserable when left alone for long stretches
  • Intelligent and curious — learns tricks, opens cabinets, and solves puzzle feeders
  • Active and playful — sprints, jumps, and climbs; stays kittenish well into its senior years
  • Affectionate lap cat once settled — curls up close, kneads, and purrs loudly
  • Social with other cats and gentle children — tolerant and outgoing, though it wants attention pointed its way

Siamese

  • Extremely vocal and communicative — will "talk" to owners constantly
  • Highly affectionate and people-oriented; hates being left alone
  • Intelligent, curious, and known for opening cabinets and doors
  • Social with other pets but demands human attention above all
  • Active and playful throughout life

Health Notes

Javanese

  • Progressive retinal atrophy (PRA) — an inherited retinal degeneration shared with Siamese lines, starting with night blindness and progressing over years; DNA testing available and recommended before breeding
  • Hypertrophic cardiomyopathy (HCM) — the most common heart disease in Siamese-derived breeds; annual echocardiogram screening recommended for breeding cats
  • Hepatic amyloidosis — a hereditary liver condition seen in Siamese-derived breeds, where amyloid deposits accumulate in the liver; unexplained weight loss with a normal appetite is the early sign
  • Asthma and bronchial disease — a higher incidence of airway sensitivity than most cats, shared with Siamese ancestry; keep dust, smoke, and aerosol triggers low
  • Dental disease — the narrow muzzle and crowded teeth raise gingivitis risk; regular dental care and annual cleanings recommended

Siamese

  • Progressive retinal atrophy (PRA) — an inherited eye disorder
  • Asthma and bronchial disease — more common in Siamese than other breeds
  • Amyloidosis — a liver disease with genetic predisposition
  • Dental issues — prone to gingivitis and tooth resorption
  • Sensitivity to anesthesia — discuss with your veterinarian

Frequently Asked Questions

How can I tell a Javanese apart from a Siamese?
Siamese have a short, fine coat and are limited to seal, blue, chocolate, and lilac points. A Javanese is longhaired and pointed in red, cream, lynx, or tortie. The long silky coat is visible from across the room.
Are Javanese cats hypoallergenic?
No — Javanese are not hypoallergenic. The single silky coat sheds less than a double coat, but they still produce normal dander and the Fel d 1 protein that drives most cat allergies.
Are Siamese cats hypoallergenic?
No — Siamese are not hypoallergenic. They produce normal levels of the Fel d 1 protein (the primary cat allergen found in saliva and skin oils) and shed dander like other shorthaired breeds. Their short coat may release slightly less airborne hair than longhaired breeds, but they are not considered a low-allergen breed. If you have cat allergies, spend time with a Siamese before adopting to test your individual reaction.

Breed Profiles & More Comparisons

Javanese

A Balinese in colors the Balinese standard does not allow. The Javanese pairs the long, silky, single-layer coat of the Balinese with the red, cream, lynx, and tortie points of the Colorpoint Shorthair. Despite the name, the breed was developed in North America, and it carries the same vocal, people-focused Siamese personality under all that silk.

Siamese

One of the oldest and most recognizable cat breeds, the Siamese is famous for its striking color-point pattern, vivid blue almond-shaped eyes, and vocal, people-oriented personality.
