They say no good deed goes unpunished...and that's definitely the case for these two guys in Bolivia! When they come upon a bull with its head stuck in between two tree branches, they stop to help the animal out by pulling the branches apart. Once the bull wiggles free, it runs straight for the men and headbutts them. It's not exactly a "thank you," but we don't blame the big guy for being spooked.

Speaking of spooked animals, this cat is protecting its human's bed at all costs. When a friend tries to sit down, the cat marks the territory with a bold hiss. We don't speak cat, but we're pretty sure that translated to: "I said what I said!"
