When a Siamese kitten is born, it weighs between three and five ounces — less than half a pound. It measures about 3 inches long and is so tiny it will be able to fit in the palm of your hand.

Siamese Cats: 0 to 6 Months

Their growth is quite dramatic over the first few weeks of life. They usually double in size by the second or third week. When they’re one month old, they should weigh about one pound.

Even though they have reached their sexual maturity, these cats still have a bit more growing to do. At six months old, a Siamese cat will weigh between 2.8 lbs and 5 lbs.

Siamese Cats: 6 to 12 Months

Generally, Siamese cats stop growing when they’re between 10 months to 12 months. Although, in some cases, they may continue until they’re 18 months.

Siamese Cats: 12 Months to 2 Years

At full maturity, a male Siamese cat weigh between 10 and 15 pounds, and a female weigh between 6 and 10 pounds. They are usually 11.5 to 15 inches long and about 8 to 12 inches tall.

They‘ll be done growing by the time they’re two, but a Siamese cat can put on weight at any point in their life. Since they’re naturally thin and have a lean and slender body, It’s easy to see if your cat is putting on too many pounds.
