You Hate Something?

So how about the animals: do they hate something too?

The best partnerships are undoubtedly those, in which both members benefit and although it can sometimes be difficult to decide whether partners support or exploit each other, there are some natural partnerships that leave no doubt as to whether there are winners or losers: in fact both are winners.
