From kittens to cats: How does the brain grow?

Kittens grow at an incredible rate, moving from tiny balls of fur into larger kittens in a blink of an eye. By the time they reach adulthood, they will be 40-50 times their birth weight! As well as experiencing rapid physical growth, kittens also undergo very fast sensory development by comparison to humans. Kittens are born blind with their eyes shut – by 2 weeks of age, their eyes open, and by 8 weeks they have already developed a broad field of both 3-D and night vision. Did you know that it takes them only 10 days after birth, to develop their tastebuds to identify the difference between bitterness, acidity, saltiness and savoury flavours? Finally, their brain and nervous system are also developing at an amazing pace, especially in the first few weeks, and within a short 3 months your kitten’s brain will be the size of an adult cat’s.

A closer look at this critical period of a kitten's life

You would be amazed to know that almost everything inside your kitten’s body develops at the same time. Apart from their brain, and their sensory systems, their muscles are growing and their bone structure is also changing, forming the locomotor system which helps your kitten move about. Their nervous system is becoming more efficient, improving and refining the messages between the brain and body – this is when they start to become less clumsy and start being more agile.

As they gain mobility, their curiosity grows. Through this period, they are constantly learning about their environment, such as how to navigate different surfaces, how to interact with people and other pets, and they quickly learn to identify safe areas of the home as well as threats. This window of learning peaks at about 8-9 weeks of age, so is the perfect time to begin exposing your kitten to many positive experiences, as well as socialisation, so they can develop into a well-adjusted adult cat. It is also a great time to kitten-proof your home to keep them safe as they play and explore!

What is the role of nutrition during this period?

The right nutrition not only feeds your kitten’s needs for a healthy development, but it’s also giving them the energy to grow and learn day after day. Always select a food with vital nutrients for healthy growth and optimal digestion. A diet with carbohydrates may assist in the development of the brain, the kidneys and red blood cells, while a food rich in Omega-3 fatty acids (DHA in particular) can help improve memory, hearing, vision and brain development.
