At What Age Do Cats Stop Growing?

Kittens are basically living, breathing, fuzzy cuteness. We love seeing their adorable eyes, and we love hearing their sweet little mews. But one of the main things that we cant get over is a kittens adorable size. We know they cant stay that way forever, but we love seeing how adorably tiny baby cats are. Yet no matter how much we may want them to stay small, a kitty has to grow up. But how long does it take? And how will we know when our cat is fully grown? Here is the guide you need to understand how your feline grows.

Most experts agree that cats reach adulthood at 12 months old, which means this is the age where their personalities have matured and solidified into how theyll behave throughout their adult lives. Around 16 weeks, kittens growth starts to slow as they pass their quickest development and most impressionable stage.

Kittens need to consume a massive amount of daily calories during their first stages of life to reach their proper size. However, if cats arent fed properly , then their growth can be stunted, which is why many shelter kittens are smaller in size than their re-homed counterparts. In addition to diet and breed, the age at when a cat is spayed or neutered also affects the growth rate.

While it is true that cats can continue to grow after the first year, their growth rate will slow down significantly afterwards.
