When we adopt a cat or dog, we realize that very soon, they’ll grow up to be adults. But time flies by and they’re suddenly not that cute little baby that used to fit in your hand. Fortunately, we have before and after photos to help us see how much they’ve changed.

We at Bright Side adore impressive comparisons and love sharing them with you even more.

“Here’s my cat 2 years later.”

“I found my cat’s old photos on my PC and decided to share this comparison.”

“He still looks like a toy 1 year later but a bit angrier…”

“Wiggles and me 13+ years later!”

“8 weeks vs 5.5 years later and she’s still my little munchkin.”

“Our first Christmas together vs our fourteenth Christmas together!”

“An impressive difference!”

It’s hard to believe that they grow this much!

“A year later and 12 pounds heavier — it’s still Dobby’s favorite toy.”

Thanks to the litter box, you can see how much this cat has grown up.

“And now he can’t fit on that shelf.”

Who could’ve thought that it’d grow into such a big cat?
