Kittens grow up incredibly fast and with our little kittens, it's not always so noticeable as it happens before our eyes. The every day changes of your kitten are impawsible to notice at first.

Then one day your kittens have been growing at an exponential rate for so long you realize it: your kittens are now large and in charge. You no longer have tiny kittens, you have grown, adult cats.

Realistically, seeing your kittens become cats is a beautiful thing to witness. The best part of seeing your kittens grow up, though, is taking a photo of them as kittens and a photo of them grown up as cats, and comparing the two side-by-side.

Whether the photo of your kittens are from a few months ago or a few years ago, seeing your kittens as kittens and your kittens as cats next to each other is the sort of thing that shoots straight through your heart in the best pawsible ways.

The cats in the pictures below had the most beautiful glow-ups, they went from confused sleepy kittens to majestic grown cats who are ready to cuddle and cause trouble any second of the day.
