History & Origin
Siamese cats were the royal cats of Siam (now Thailand), depicted in 14th-century Thai manuscripts. The first pair reached the U.S. in 1878 as a diplomatic gift to President Hayes. Modern show Siamese have a more extreme wedge head than 'traditional' (apple-head) Siamese.
Temperament & Personality
Loud, social, intelligent. Siamese yowl persistently to demand attention, food and play. They form intense bonds with one or two humans and dislike being alone.
Health Watchouts
Top conditions reported by CFA/TICA parent clubs, AAFP, the Winn Feline Foundation, and the Merck Veterinary Manual. Discuss screening with your vet — especially before breeding or insuring.
Asthma
Elevated vs. mixed-breedChronic airway inflammation causing coughing and wheezing.
Screening: Annual physical with breath sounds; minimize household irritants
Amyloidosis
Inherited in some linesProtein deposits in liver causing late-life liver failure.
Screening: Pedigree review; annual senior bloodwork
Progressive retinal atrophy
Rare with screeningInherited blindness.
Screening: DNA test of parents
Periodontal disease
70%+ of cats by age 3Plaque hardens to tartar and inflames gums, leading to tooth loss and bacteremia.
Screening: Annual oral exam; daily brushing or VOHC-approved dental treats; professional cleaning every 1–2 years
Hypertrophic cardiomyopathy (HCM)
Breed-elevated riskThickening of the left ventricular heart wall — the most common heart disease in cats. Lower prevalence than other breeds; still recommended to screen.
Screening: Annual echocardiogram from a board-certified cardiologist; DNA test where available (Maine Coon, Ragdoll)
Enrichment & Play

Frequently Asked Questions
Why are Siamese cats so loud?
Loud, persistent vocalization is a defining breed trait. They use their voice to communicate every need. If quiet matters, choose a different breed.
Can Siamese cats be left alone all day?
Not well. They develop separation anxiety, over-groom and become depressed. Adopt in pairs or choose a different breed if you work long hours.
Are Siamese cats hypoallergenic?
They produce somewhat less Fel d 1 than average and shed minimally. Many mild allergy sufferers tolerate them well.
