Health now and always

Kittenhood is a stage of massive physical and behavioural changes. Nutrition tailored to their specific developmental needs can help them grow from fragile young kittens to strong, healthy cats.

Kittenhood – An amazing transformation

During the first months of life, your kitten will go through an amazing transformation. Royal Canin Kitten formulas offer nutrition tailored to their unique needs at this vital time.

1.A sense of sight

It takes up to four weeks for a kitten’s sight and connected behaviour (spatial perception) to be fully developed.

2.Immunity and defence

In their first six months your kitten's immature immune system must help protect them from millions of germs.

3.Tripling their weight

At birth most kittens weigh around 100 grammes. Within a week they will double that weight, and triple it within 21 days.

4.Healthy bones

In the first year of life your kitten's bones must grow to become four times stronger than concrete.

5.Extraordinary growth

In the first six months of life a kitten will grow as much as a 10 year old adult child.

When kittens are born, they can barely move or hear, and their eyes are completely closed. At around five days old, they will begin to open their eyes. This is also the time when they start to gain between 10 g to 30 g each day.

By this time, their sense of smell is fully matured and their hearing is well-developed. Kittens begin to develop adult sleeping patterns, motor abilities and social interaction. Key social skills develop through interaction with littermates and their mother.

Understanding your kitten's health

It's important to understand your kitten's routines and behaviour, so you can quickly recognize the signs if something isn't right. It's also important to understand a few key milestones, such as vaccinations and booster injections.

Your kitten's behaviour

Kittens communicate with you in a number of ways. Reading body language and expressive behaviours, and listening to the sounds they make can tell you a lot about how they're feeling and what they need from you.
