Kittens typically reach a length and weight close to their full-grown size by 9 to 12 months of age. After the 1-year mark, most cats continue to grow at a much slower rate until at least 18 months of age. Large breeds, such as Maine coon cats, typically take even longer to grow to their full size. These cats may not be fully grown until they reach 2 to 4 years of age.
