Dublin Zoo

It's been over a year since a video of a tiger reacting angrily to being woken up from a (big) cat nap went viral but, clearly, the Internet just can't get enough. Originally posted to YouTube in April 2016, a video of the grumpy tiger was reposted to Twitter on July 1 and has many sleep-deprived tweeple relating hard to it.

India's only gorilla, Polo died at Mysore Zoo here due to respiratory infection and age related ailments.
