what animal is most likely to be able to take over the world, other than humans?
Cockroaches.
I think we all know :D 
I think these two will be here forever ! Roaches and Twinkies !
I think we all know who will rule world! Me and my clansmen!
It will all be made into soylent green for us to eat!! Yummy
Instantly thought of the serie: Zoo regarding this question.
So I have to go with that they all will form into a collaborating furry army to take us down once and for all.
At first we thought it might be the bees,
however humans are killing them off with pestisides.
Might be this one :)
