One unlucky postal worker has been dealing with a hyper-territorial feline on his route, so he decided to film his daily routine.

We wonder what exactly happened to this cat to make him so mail-aggressive. Maybe he's upset over the recent increase in postage, or his owner has trained the kitty to shred all bills on the spot.

At any rate, despite the daily battles, the mailman seems to have a pretty good attitude about the whole thing. The cat? We're not so sure about the cat.
