On Tuesday, actor Tom Hiddleston and Silicon Valley's Thomas Middleditch were guests on The Late Late Show with James Corden where they got to hang out with a couple of two-month-old clouded leopard cubs. Try not to lick your computer screen when you see the handsome actor (and the other guy) (just kidding, he's cute, too) snuggle the tiny baby kitty.

Hanna explained that the leopards are endangered (there are only about 200 or 300 left in the world, according to him) and that leopards are the only cats that spend 90 percent of their lives in trees (because they think they're birds. Stupid cats).

And then, just when you think it can't get any cuter, BOOM—penguin. 

"Deal with it."
"Deal with it."

Good to see Jack Hanna is still wearing the traditional "exotic animal handler on late night talk show" uniform (as seen here on Will Ferrell).
