As the title states: All types of animals can be jerks.  I know this first-hand.  My
cat, Buster, pulled a stunt this morning (he was hell-bent and
determined to push all of my stuff off of my night stand--and almost
succeeded.  This video, uploaded by FRlKK on March 11, 2013, proves that animals--from cats to kangaroos--can be... well... jerks.

I have two favorites from the video above: 1) the squirrels and 2) the dog stealing the snow sled.

Yep.  They're jerks.
