WATCH: Tigers get into a heated argument at Dublin Zoo - and it's not pretty
Catching a glimpse of the big cats in Dublin Zoo can be difficult at times - but this family got more than they bargained for on their visit.
At the beginning of this clip, one of the large tigers can be seen trotting up and along the spectator window much to the delight of the watching children.
But the striped feline ignores his adoring crowd and makes a beeline for his oblivious resting companion, slapping him with a huge paw.
Being rudely awakened is not nice for anyone - and this roaring animal showed his pal just how peeved off he was.
Take a look at his reaction here.
