Good and evil in the animal kingdom

Make a list of animal adjectives - how many are good and how many are bad?

The foxy wife and her beefy beau,
with their boy like eagle and girl like doe,
look down upon their neighbours - terribly so!

That porky man and his mousey lady
two elephantine kids and a crabby baby
shout 'You cow!' 'You pig!' 'You bitch!' - you see?

But there's something fishy, I smell a rat!
How can fox and cow better mouse and cat?
To all animals I sheepishly apologise for that.
