No one is born knowing that cats can be rather temperamental playmates. Indeed, that's a bit of knowledge that often must be learned from scratch — or scratches.

This kangaroo, for example, recently got an unforgettable lesson on the fickleness of felines. In a video uploaded to YouTube, the friendly 'roo named Hop is seen simply trying his best to cozy up to a napping cat, offering a few friendly head pats, when things suddenly get a little nasty.

The cat basically loses his chill. After the incident, Hop is left to wonder: Was it something he did?


Yes, but don't feel too bad. We've all been there. Fortunately, relations between Hop and the mercurial cat aren't always so hostile.
