Siamese Cat: Temperament, Size, Lifespan & Care

Siamese temperament and personality

The CFA describes the Siamese as affectionate, intelligent and clingy, a cat that wants to be with you or involved in whatever you are doing and can be insistent about it. VCA rates intelligence at 5 out of 5 and chattiness at 5 out of 5.

The voice is the defining trait. The CFA says Siamese are very vocal, with a large range of sounds, and protest loudly when they want something. For people who like a conversational cat, that is the appeal. For a quiet apartment or a light sleeper, it is worth thinking about before you commit.

How big do Siamese cats get?

The CFA describes a medium-sized cat that is long, slender and graceful, with fine bones and firm muscles, and notes males may be larger in proportion than females. VCA lists an adult weight of 5 to 8 pounds.

Siamese are naturally lean, so a healthy one looks long and fine-boned rather than thin. VCA notes that diet should be set with a veterinarian because needs vary with life stage. Run your hands along the ribs every few weeks, and ask your vet to score body condition at checkups.

Siamese lifespan and common health issues

VCA gives a lifespan of 12 to 15 years. The CFA says most Siamese are healthy, but names progressive retinal atrophy, an inherited eye disease with a DNA test, and amyloidosis, which affects the liver and has no genetic test yet. VCA notes that anxiety when left alone can lead to overgrooming and hair loss, and that young Siamese may suck wool or eat non-food items.

Ask a breeder whether the parents have been DNA tested for progressive retinal atrophy, and ask about amyloidosis in the kitten's lines, as the CFA advises. Ask your vet about dental care and what to do if your cat starts chewing fabric. Vomiting, not eating or straining in the litter box needs a vet promptly.

Exercise and activity needs

The CFA calls the Siamese active, and VCA describes a determined climber that needs a sturdy cat tree or shelves. Plan on daily play with wand toys such as a feather teaser wand, balls and puzzle feeders, and vertical space for climbing, such as a tall cat tree.

Short sessions two or three times a day keep a Siamese busy and less likely to find its own entertainment. Many learn to walk on a harness. Fetch is common in the breed, so try tossing a small toy and see whether it comes back.

Siamese grooming and shedding

The short, fine, glossy coat is easy. VCA says a quick weekly comb removes dead hair and that bathing is rarely needed because the breed is a fastidious self-cleaner. The CFA suggests stroking with damp hands or a rubber brush to lift loose hair, and VCA rates shedding at 2 out of 5.

VCA notes the coat darkens with age, which is normal for a pointed cat. Brush the teeth if your cat will accept it, trim the claws every couple of weeks and check the ears when you groom.

Training a Siamese

VCA rates the Siamese 4 out of 5 for ease of training. Many learn to come when called, sit, high-five, fetch and walk on a harness. Short sessions with small food rewards and a clicker work well.

Train the behaviors you want before the cat trains you. Reward quiet, and avoid answering demand meows instantly, or the volume rises. Teach the cat to use a scratching post and cat tree early with treats and play.

Are Siamese cats good with kids and other pets?

VCA rates the Siamese 3 out of 5 for being good with children and 3 out of 5 with dogs. Respectful, older children who play with wand toys rather than grabbing the cat usually make good companions for the breed.

VCA says Siamese often do well with another cat, ideally another Siamese, especially in homes where people are out during the day. Introduce new pets slowly, starting with scent swapping and short supervised meetings.

What a Siamese needs at home

Plan for height and company. A tall, sturdy cat tree or wall shelves, window perches, a scratching post, wand toys, puzzle feeders and a cozy bed in a warm spot are the basics. A second cat is worth considering if the home is empty all day.

For care, keep a fine comb or rubber brush, nail clippers and a cat toothbrush, and a harness if you plan to walk your cat. Keep cords, hair ties and fabric scraps out of reach of a young cat that likes to chew. Ask your vet about dental and eye checks.
