Under normal feeding, Ragdoll cats generally mature at 3-4 years old, and can reach about fifteen kilograms when they reach adulthood. Published cats can grow up to about 20 kilograms, and some male cats may grow up to 10 kilograms at one year old. As mentioned above, an adult female cat is about 6-7 pounds, slightly smaller than a male cat, and a male ragdoll cat is heavier than a female cat. ​​​​​​

Ragdoll cats are one of the largest pet cats. Adult male ragdolls can reach 60 to 80 centimeters in length. The better the bloodline, the larger they will generally be. If you want the Ragdoll to grow well, you need to supplement it with enough nutrients. If possible, you can make homemade cat rice for the Ragdoll cat and feed it more meat. During the growth and development process, cats need to consume more nutrients, such as calcium, than small and medium-sized cats. Therefore, owners can feed Ragdoll cats some biotin, turtle egg powder, and egg yolk lecithin to promote their bone development and make Ragdoll cats larger.

Under normal circumstances, adult Ragdoll cats can reach more than 40cm, while male Ragdoll cats can grow to about 60cm. However, this data is not fixed, and some blood lines are better. For example, high-level Ragdoll cats with Australian and Polish blood lines can reach 80cm in length.
