When Does A Cat Reach Full Size?

Many kitten owners may ask, “When does a cat reach full size?” Kittens have different growth rates and reach maturity of different times depending on the cat breed of the kitten.

American shorthair kittens typically reach full size within the first three years and often within the first two years. Several cat breeds mature faster or slower than American shorthair kittens.

A cat breed that has kittens that mature fairly quickly is the Singapura cat breed. Singapura kittens are between fifteen and twenty-four months old when they reach full size.

Chartreux kittens reach full adult size when they are about three years old. Kittens of the Somali cat breed are about eighteen months old when they reach full size.

Most Bengal kittens reach full size by the time they are three years old, but some take slightly longer. Savannah kittens typically reach full adult size in two to three years.

The Chausie cat breed is a hybrid of domestic cats and jungle cats. Chausie kittens reach full size when they are two to three years old. American Bobtail kittens also take up to three years to reach adult size.

Ragdoll kittens may take up to five years to reach full size. However, most Ragdoll kittens will reach full size when they are from three to four years of age.

Kittens of some cat breeds reach full size in the same timeframe as Ragdoll kittens. Maine Coon kittens typically take three to four years, but may take up to five years to reach full size. Turkish Van kittens can take up to five years to be full size.

The Norwegian Forest Cat is a slow-maturing cat breed. The kittens often take four to five years to reach full adult size. Siberian cats can also take up to five years to reach full size.

Some cat breeds go through other physical changes besides size while they are kittens. Egyptian Mau kittens may be born with amber eyes, but the eyes turn green by the time the kitten is about eighteen months old. Many cat breeds experience changes in their coats and coloring as they mature.

A kitten does not need to reach adult size before being spayed or neutered. Waiting too long to spay or neutor a cat can lead to some undesirable consequences such as spraying in males or an increased risk of mammary cancer in females.
