Tigers are like all cats in that they need to squeeze in eighteen plus hours a day of beauty sleep, and they really don't like to be disturbed while they're catching some z's.
But unlike most other cats a tiger will launch a furious attack at anyone who dares disturb their sleep, even if that attack leads to an awkward tension between bros in a shared enclosure.
Is that the tiger from The Hangover? Looks like Mike Tyson has taught him some moves!
