Cats.

Cats are like rats, They taunt you and haunt you, And make you feel bad, Disclaiming the things you almost once had, The mirror that you hung on your front bedroom wall, The vase from your great grandmothers vault, The big giant claws are never at rest, You throw it outside and hope that it dies, Feel bad though and turn, Only to see your big furry friend, The one you knew, The cute and cuddly one, You let it in, It meows and says thank you, Rubbing against you, Giving you one last kiss before he goes, And destroys the house.
