If you grow up with a cat over the years, it goes without saying that it will feel like a member of your family – nothing less. These before and after pictures of cats growing up remind us that, no matter for how long you live with your furry friend, they're parts of our families that grow and age with us.

People and pets share lots of wonderful moments while growing up or growing old together. Pets grow at such a fast pace that you may not even notice how your little friend, whom you just brought home in a little box, doesn't fit in that box anymore.

We’ve created a post of cute before and after dogs, so now it’s time for cats. If any cat lovers have their own before-and-after photos that show their kitties growing up, we'd love to see them added to this list!
