The legal minimum age is a lower limit, not an ideal target. Kittens need time with the mother cat and littermates to learn social behaviour, bite inhibition, grooming and normal cat communication. Leaving too early can increase stress and behaviour problems.

## Why many breeders wait longer

Many responsible catteries keep kittens until around 12 or 13 weeks. This allows more complete socialisation, vaccination planning and observation of health and character. A kitten that is eating independently at 7 weeks is not automatically ready for the world.

## Warning signs

Be cautious if a seller wants kittens gone as soon as legally possible, cannot show the mother cat, or says a very young kitten will bond better with you. Good bonding does not require early separation. It requires careful handling and a safe transition.

## What to ask

Ask the date of birth, planned collection date, vaccination schedule, parasite treatment and how the kittens are socialised. Combine this with [kitten socialisation](https://nestjes.nl/en/knowledge-center/kitten-socialisation) to judge whether the litter is being raised well.
