When assembling a lighthearted video gallery of animals who look like they could prod some serious buttock, it's important to remember a few things: one, no animals who could actually destroy someone with a bite - sorry sharks - and two, cats always take priority.
This is why our '11 Animals That Can Kick Your Ass' video collection we've got for you below has so many felines, be they of the ninja variety, the kung fu kind or the plain ol' despicable brand.
Elsewhere we've got ethically questionable penguins, rather possessive geese and bear cubs that swing a stick well. In other words, you have been warned...
