Siamese Cat Breed Information

Also known as: Royal Cat of Siam, Modern Siamese

Slender, blue-eyed colourpoint cat from Thailand. Among the most vocal and people-bonded breeds in the world. Smart, demanding, and a poor fit for households where the cat is alone all day.

A highly affectionate, highly trainable, great with young children cat. On the practical side: low grooming demands and minimal drool. The trade-off is vocal.

About the Siamese.

The Siamese is the loudest, most demanding, most trainable cat most NZ households will ever consider. It is colourpoint, blue-eyed, slender to the point of looking lanky, and bonded to its people in a way closer to a small dog than a typical cat. NZCF and Catz Inc both recognise the modern wedge-headed type, with the older apple-headed cats now registered separately as Thai.

Siamese live a long time, often 15 to 20 years, and the breed comes in seal, chocolate, blue, lilac and a growing range of newer point colours.

Personality and behaviour

A Siamese is in every conversation in the house. They follow their humans from room to room, talk constantly, and dislike being on the wrong side of any closed door. The voice is loud and distinctive, often described as crying or yelling. The breed is highly people-bonded, openly affectionate, and intolerant of being alone for a working day.

They are the most trainable cat on this site. Clicker work, harness walking, fetch, recall and even simple agility sit comfortably within the breed’s mental stimulation needs. The flip side is that an under-stimulated Siamese is destructive and noisy, opening drawers, shredding paper, and yelling at 3am.

The surprise for new owners is how dog-like the Siamese turns out to be. Greeting visitors at the door, riding on shoulders, and following the household around the house are all normal Siamese behaviours.

Care and grooming

Coat care is among the lightest of any pedigree cat. A weekly wipe with a damp chamois or rubber grooming mitt removes the small amount of shed and is enough for show condition. Bathing is rarely needed.

Where Siamese are demanding is in mental routine. Plan on 30 to 45 minutes of structured play and training daily, plus puzzle feeders, vertical space, and rotation of toys. A bored Siamese finds its own entertainment, usually loudly.

Dental care matters more than for most breeds. The slender Siamese jaw produces crowded teeth and a higher rate of dental disease. Brush teeth weekly, schedule annual dental checks, and budget for occasional cleans under anaesthetic.

Indoor vs outdoor in New Zealand

Indoor or catio. The Siamese is a moderate prey-drive hunter, which adds to the standard NZ case for keeping cats contained. The bigger arguments here are theft and traffic. The breed is friendly to strangers, conspicuous, valuable, and not street-aware. SPCA NZ guidance to keep cats contained applies cleanly to Siamese.

The breed handles indoor life better than most active cats because it is so people-bonded. A Siamese will follow you around an apartment all day rather than seeking outdoor stimulation. Pair this with a catio or window perch and the breed thrives.

Living arrangements

Two-cat households work better than single-cat households for Siamese, especially if the household is empty during a working day. Common pairings are two Siamese siblings, a Siamese with a Burmese or Tonkinese, or a Siamese with another active social breed. Avoid pairing with a cat that wants to be left alone (a senior British Shorthair, for instance), as the Siamese will harass.

Vertical space matters. Cat trees, shelving, window perches and a clear running circuit through the house keep Siamese happy. The breed is athletic and climbs.

Where to find a Siamese in New Zealand

The NZCF and Catz Inc breeder directories list NZ-registered Siamese breeders (NZCF Siamese breeders, Catz Inc Siamese). Expect a three to six month waitlist for kittens, with prices typically NZD 1,200 to 2,800. Ask whether the breeder works with traditional or modern type, what point colours their lines produce, and whether parents have been screened for breed-typical heart and kidney conditions.

Adult Siamese do appear at SPCA NZ and at all-breed cat rescues, often surrendered when their vocal habits or attention needs prove too much for the original household. Adoption costs NZD 150 to 350 and the cat is desexed, vaccinated and microchipped.

Insurance and lifetime cost

The Siamese claim profile is dominated by dental disease, asthma and bronchial disease, occasional cancers in middle to late life, and breed-line amyloidosis. Reputable breeders screen parents for known heritable conditions. Ask insurers about cover for hereditary conditions and ask whether asthma is covered as a chronic condition or only acute episodes. Lifetime cost is mid range for a pedigree cat, with food and parasite control being unremarkable, but dental and chronic condition costs adding up over the breed’s long lifespan. Plan on $250 to $450 a month all-in.

The Siamese in NZ.

  • Popularity: One of the most established pedigree breeds in NZ, with a long Catz Inc and NZCF history. Ranked among the top six cat breeds in NZ by Companion Animals NZ pet survey data.
  • Typical price: NZ$1200–2800 from registered breeders or rescues
  • Rescue availability: occasional
  • NZ climate fit: Lean coat and slender frame mean cooler regions need warm sleeping spots. Auckland and Northland summers are well within tolerance; central Otago winters need a heated bed or indoor warmth.
  • Living space: Apartments work well if the household is home a lot or runs two cats. Vertical space, puzzle feeders and scheduled play are essential.

Who the Siamese is for.

Suits

  • Owners home most of the day, or with a second cat for company
  • People who want a vocal, interactive, dog-like cat
  • Households happy to clicker-train and harness-walk

Less suited to

  • Long-hours-out single-cat households
  • Owners who want a quiet cat
  • Households intolerant of late-night vocal demands

Common questions.

Are Siamese really that vocal?
Yes. The breed is among the most vocal cats in the world, with a loud, low-pitched voice used regularly to demand food, attention, conversation and door opening. Households sensitive to noise, particularly at night, should pick another breed.
Should a Siamese be left alone all day?
No. Siamese suffer from separation stress more than most cats and develop destructive or self-grooming behaviours when isolated for long stretches. Either be home most of the day, work from home, or commit to a second cat for company. A Burmese, Tonkinese or another Siamese pairs well.
Are modern Siamese different from the cats my grandmother had?
Yes, often markedly. Mid-20th century Siamese had rounder heads and stockier bodies, closer to the Thai. The modern show Siamese is slender, with a wedge-shaped head, very large ears and almond eyes. Both types are recognised by NZCF and Catz Inc, but you have to ask the breeder which they work with.

If the Siamese appeals, also consider.
