Tonkinese

Key Visual Markers

• Mink coat pattern — a unique intermediate between the Siamese point pattern and the Burmese solid color; the body color is a warm, muted shade of the point color rather than a pale cream, creating a soft, harmonious contrast without the high-contrast point definition of a Siamese; recognized in 12 colors including natural mink (warm brown with dark brown points), champagne mink, blue mink, and platinum mink
• Large, expressive aqua-blue eyes — the breed signature; the eye color ranges from blue-green to green-blue, sitting in the middle of the color spectrum between the Siamese vivid blue and the Burmese gold; the color develops fully by 4-6 months of age and the depth and clarity of the aqua shade are judged in the breed standard
• Modified wedge-shaped head that is a gentle, rounded wedge — shorter and wider than the Siamese wedge with a visible break at the eye level and a rounded muzzle and forehead; the CFA standard describes it as "a modified wedge with a gentle curve from forehead to nose"
• Medium-sized ears with slightly rounded tips, set as much on the side as on the top of the head — blending into the modified wedge head shape without protruding; minimal inner-ear furnishings, with the ears continuing the line of the wedge
• Muscular, medium-sized body that is neither svelte like the Siamese nor cobby like the Burmese — the CFA standard calls it "intermediate in type with a well-rounded chest and medium-length legs"; the cat feels surprisingly solid when picked up, a middle weight between the fine-boned Siamese and the dense-bodied Burmese
• Short, fine, soft coat with a satin sheen that lies close to the body — minimal undercoat, similar to the Burmese coat in texture but without the solid color gloss; the coat is the shortest of the three related breeds and requires almost no grooming

Temperament & Traits

• Friendly and outgoing — more people-oriented than Burmese but less demanding than Siamese; greets visitors, wants to be involved in all household activities, and adapts well to new people and environments
• Playful and active without being hyperactive — enjoys fetch, puzzle feeders, and interactive play but settles happily for lap time and petting sessions; a good balance for households who want an engaging cat without the intensity of a Siamese
• Highly intelligent — learns tricks, opens doors, and responds to its name; needs mental stimulation to prevent boredom but is less destructive than wedge-head breeds when under-stimulated
• Social with other pets and children — the breed is known for its adaptability and rarely shows aggression; Tonkinese often become the "ambassador" in multi-pet households
• Vocal but moderate — communicates with a soft, melodious voice that is quieter and sweeter than the Siamese shout; family members report distinct vocal patterns for different requests
• Heat-seeking — the short single coat offers modest insulation; Tonkinese gravitate toward sunny spots, blankets, heated beds, and human laps; they often sleep under the covers in colder months

Health Notes

• Hypertrophic cardiomyopathy (HCM) — reported in the breed, inherited from both Siamese and Burmese ancestry; regular echocardiogram screening recommended for breeding cats; early detection through annual screening improves management outcomes
• Feline lower urinary tract disease (FLUTD) — some lines show predisposition; high-moisture diet and stress management are preventive measures; symptoms include straining to urinate, blood in urine, and urinating outside the litter box
• Dental disease — moderate muzzle length contributes to some tooth crowding; regular dental care and annual cleanings recommended; Tonkinese tend to have better dental alignment than brachycephalic breeds but worse than natural mixed-breed cats
• Gastrointestinal sensitivity — some Tonkinese have sensitive stomachs and react to abrupt diet changes with soft stool or vomiting; gradual food transitions (over 7-10 days) and consistent high-quality diet help manage this tendency
• Progressive retinal atrophy (PRA) — a retinal degenerative disease reported in the breed, inherited from Siamese ancestry; DNA testing available; affected cats develop night blindness that progresses to complete vision loss over several years
