Our kitten ageing chart helps you to tell how old a kitten is at a glance
Whatever their age, there’s no denying that kittens are adorable. But figuring out how to tell how old a kitten is from pictures is a useful way to ensure you’re caring for your cat as it develops. While it can be tricky to work out a kitten’s age just by looking, our at-a-glance kitten ageing chart is here to help you out.
Remember, it is important that kittens stay with their mother for at least the first eight weeks of life. Removing them before this time can have dire consequences for their behaviour, health and survival.

- Wondering when do kittens open their eyes? The answer is anytime between five-14 days. After birth, a kitten’s eyes remain closed, their ears are folded and they are unable to stand
- They’ll still have an umbilical cord – this will fall off by day three
- Kittens suckle from their mother every two hours
- They need help with toileting too. They’ll need their mother to lick their perineal area to stimulate toileting
