Understanding Cat Growth Stages

During the initial months of life, kittens experience rapid growth akin to human babies. This period is marked by significant changes in size and development. Kittens are known for their playful antics and boundless energy during this phase.

Rapid Growth Phase: Kittens grow the most during the first few months of life. They may double or even triple their birth weight within a matter of weeks.

Adolescence (6-12 Months)

Around 6 months, kittens start transitioning into adolescence. Growth slows down during this stage, and cats become more independent.

.Slower Growth: While not as rapid as before, cats continue to grow during adolescence, albeit at a slower rate.
