I have never seen a litter of kittens quite like these tiny ones. They are the craziest, springiest foster babies I've seen! And those butt wiggles!!!

"Out of all the kittens we've fostered over the years, I can't recall a crazier lot than these four! They came in pretty shy, but as you can see, have quickly turned it around!" the Itty Bitty Kitty Committee wrote.

I could watch this all day! Riveting entertainment!

Kitties go vertical! The ending made me literally laugh out loud.
