This Compilation Of Kittens Learning To Use Stairs Is The Most Adorable Video You'll See This Week

It's World Smile Day, and we can think of no finer compilation to celebrate it than this.

Because, as we all know, the only thing cuter than a video of a kitten is LOTS of videos of kittens. Preferably doing something ultra-cute like, ooh, I dunno, tackling stairs..?

Thank you, internet!
